PREFACE

 

For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that, if it were possible, they shall deceive the very elect.

Matthew 24:24 — King James Version Holy Bible

 

2 Thessalonians 2 — King James Version Holy Bible

The Man of Sin

Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him, That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand. Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition; Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God. Remember ye not, that, when I was yet with you, I told you these things? And now ye know what withholdeth that he might be revealed in his time. For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way. And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming: Even him, whose coming is after the working of Satan with all power and signs and lying wonders, And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved. And for this cause God shall send them strong delusion, that they should believe a lie: That they all might be damned who believed not the truth, but had pleasure in unrighteousness.

Stand Firm

But we are bound to give thanks alway to God for you, brethren beloved of the Lord, because God hath from the beginning chosen you to salvation through sanctification of the Spirit and belief of the truth: Whereunto he called you by our gospel, to the obtaining of the glory of our Lord Jesus Christ. Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.

Now our Lord Jesus Christ himself, and God, even our Father, which hath loved us, and hath given us everlasting consolation and good hope through grace, Comfort your hearts, and stablish you in every good word and work.

 

Daniel 12 — King James Version Holy Bible

Michael’s Deliverance and the End Times

(Revelation 1:1-3)

And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book. And many of them that sleep in the dust of the earth shall awake, some to everlasting life, and some to shame and everlasting contempt. And they that be wise shall shine as the brightness of the firmament; and they that turn many to righteousness as the stars for ever and ever. But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased.

Then I Daniel looked, and, behold, there stood other two, the one on this side of the bank of the river, and the other on that side of the bank of the river. And one said to the man clothed in linen, which was upon the waters of the river, How long shall it be to the end of these wonders? And I heard the man clothed in linen, which was upon the waters of the river, when he held up his right hand and his left hand unto heaven, and sware by him that liveth for ever that it shall be for a time, times, and an half; and when he shall have accomplished to scatter the power of the holy people, all these things shall be finished. And I heard, but I understood not: then said I, O my Lord, what shall be the end of these things? And he said, Go thy way, Daniel: for the words are closed up and sealed till the time of the end. Many shall be purified, and made white, and tried; but the wicked shall do wickedly: and none of the wicked shall understand; but the wise shall understand. And from the time that the daily sacrifice shall be taken away, and the abomination that maketh desolate set up, there shall be a thousand two hundred and ninety days. Blessed is he that waiteth, and cometh to the thousand three hundred and five and thirty days. But go thou thy way till the end be: for thou shalt rest, and stand in thy lot at the end of the days.

 

I have included the following two articles because I believe God’s people, those renewed of mind and spirit obeying and serving Jesus Christ the Lord and God our Father need to be aware of events occurring which coincide and reinforce Scripture.

There are and will be many signs and wonders.

Knowledge has and will increase. At a pace that man cannot keep up. We’re already at this point in the last of the last days.

Also, as regular readers of A Crooked Path know I have always written and continue to write how the war between God’s people and science ought not to exist since Almighty God and Jesus Christ are The Master Scientists and created all. Including all the laws of science, of physics. To compare God and Christ’s knowledge to man’s, for lack of better comparison for some semblance of comprehension which still does not to adequate comparison — God and Christ’s knowledge could be seen as all the water on earth. In all the oceans, seas, lakes, rivers, streams, underground aquafers, in every drop of water on this earth. And man’s knowledge in comparison would be like one neuron of one atom of one molecule of one solitary drop of water on all the earth.

Many true believers balk at proving or testing all things as they can’t help but have one solitary verse speaking to them in their heads, especially since the world uses it against Christians continually, and that is Matthew 7:1 — “Judge not, lest ye be judged.” If taking this one verse out of context as the world does, and many professed believers also do guilt comes over the individual with regard to “judging.” However, as I’ve written many times previous, and have the following quote permanently on the home page of A Crooked Path;

“It shall greatly help ye to understand the Scriptures if thou mark not only what is spoken or written, but of whom and to whom, with what words, at what time, where, to what intent, with what circumstances, considering what goeth before and what followeth after. ” ~ Miles Cloverdale

We need to look at all Scripture to discern wisely and more completely. The world stops at Matthew 7:1 and goes no further because that fuels their deceptive argument. They serve their master, the devil and he does not want discernment, understanding and the truth of the Scriptures to be revealed. He wants people confused. At each others throats. Rebellion, anger, animosity, warring among people. But if we even read the next few verses in Matthew 7 we discover;

For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured to you again. And why beholdest thou the mote that is in thy brother’s eye, but considerest not the beam that is in thine own eye? Or how wilt thou say to thy brother, Let me pull out the mote out of thine eye; and, behold, a beam is in thine own eye? Thou hypocrite, first cast out the beam out of thine own eye; and then shalt thou see clearly to cast out the mote out of thy brother’s eye.

Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you.

Matthew 7:2-6 — King James Version Holy Bible

Examining Scriptures, all Scriptures and not taking something out of context, we come to the understanding, or should, that Jesus is not saying we are not to judge, but rather Christ is teaching us HOW WE ARE TO JUDGE — we are to judge all things, test all things but mercifully and according to the Word of God. We need to humbly submit the thing in question to the Lord and ask Him to show us if it is of Him, His Spirit, of God or if the thing, the sign or wonder is from satan and the world. We need to go to the Word of God in prayer and humility and seek the answer in the Bible where all answers to any question can be found and revealed to us for our instruction and help. If the sign or wonder is from Jesus Christ the Lord and God our Father it will bear true witness within our spirit, we who have the Spirit of Truth within us will be able to witness and hear that truth. If we are uncomfortable about a sign, a thing — anything — could be any sign, wonder, apparent miracle, anything at all including what a person might be saying, writing or preaching, what we might hear along our way in this fleshly life — this could be and most likely is the Holy Spirit warning us to TEST THAT THING.

Man imagines himself a god and man of the world strives to make himself a god through increased knowledge. The quest for eternal life. To create Utopia. To prove various theories.

God will permit man’s knowledge to increase to a certain point. For many things to be revealed.

One, such as this gravitational waves, or bends, ripples in the time space continuum which Albert Einstein wrote of in theory but could never prove — to worldly man they miss the point of this discovery. What this discovery reveals is that our knowledge is as described above and that God and Christ, creators of all things including all science, have made it possible to bend time, to cause ripples in time and space through cataclysmic events — just through Their will.

I include this also so those in the faith of Jesus Christ the Lord increase in their faith through their knowledge of what is occurring daily in this evil sin-filled world where man does not give God or Christ the honor, the glory, the praise, the credit and refuses to believe, to bow humbly before God and Christ and acknowledge Them in their learning of these things man learns along the way which God allows man to learn.

To increase faith and obedience in God and Christ, to God and Christ so as to not be led astray. To not fall prey to the signs and wonders man brings forth.

For example, what the massive experiments at CERN might eventually reveal.

What these experiments at the Laser Interferometer Gravitational-wave Observatory (LIGO), mentioned in the article below might reveal.

What the signs and wonders of the coming Antichrist and his false prophet might reveal.

Do not be deceived or swept up and away in any or all of this.

Do not permit any of this to consume you, frighten you, lead you away from the faith — instead may knowledge of these things draw you ever closer to God our Father, Christ our Saviour and to the life, truth and instruction of God’s inerrant word, the Holy Bible.

This New AI Program Could Speed Up the Search for Gravitational Waves

A new software program that uses artificial intelligence can help rapidly detect and analyze gravitational waves — ripples in the cosmic fabric of space-time — from catastrophic events such as collisions between black holes, a new study finds.

The new technique, called deep filtering, can help researchers see cataclysmic events that current software might not detect, such as titanic mergers in the hearts of galaxies, according to the authors of a new paper describing the work.

Gravitational waves are ripples in the fabric of space and time. They are generated when any object with mass moves, and they travel at the speed of light, stretching and squeezing space-time along the way.

Gravitational waves are extraordinarily difficult to detect, and the ones that scientists can detect are from exceptionally massive objects. Although the existence of gravitational waves was first predicted by Albert Einstein in 1916, it took over a century for scientists to successfully detect the first direct evidence of gravitational waves, using the Laser Interferometer Gravitational-Wave Observatory (LIGO) to spot the gravitational aftermath of two black holes smashing together.

The discovery of gravitational waves earned three scientists the 2017 Nobel Prize in physics in October 2017. Since then, researchers have also detected gravitational waves from a colliding pair of dead stars called neutron stars — findings that might have helped solve the decades-old mystery of how some of the universe’s heavy elements were created.

However, the software that currently analyzes the signals that gravitational-wave observatories detect can take several days to narrow down what kind of event might have generated those gravitational waves, study co-author Eliu Huerta told Space.com in an interview.

Moreover, this software is specialized to detect mergers between objects that are in roughly circular orbits with one another and relatively isolated from their surroundings, according to Huerta, a theoretical astrophysicist at the University of Illinois at Urbana-Champaign’s National Center for Supercomputing Applications. The software will likely fail to detect gravitational waves from objects in areas where stars are densely packed together, such as the nuclei of galaxies, where the gravitational pulls of nearby stars can distort orbits from circular to more “eccentric” or oval in shape, Huerta said.

Now, the study authors suggest that artificial-intelligence software could help greatly speed up the analysis of gravitational waves, as well as “[enable] the detection of new classes of gravitational-wave sources that may go unnoticed with existing detection algorithms,” Huerta told Space.com.

The new AI software involves artificial neural networks, in which artificial components dubbed “neurons” are fed data and cooperate to solve a problem, such as recognizing an image. A neural network then repeatedly adjusts the connections between its neurons and sees if these new connection patterns are better at solving the problem. Over time, this process of trial and error reveals which patterns are best at computing solutions, mimicking the process of learning in the human brain.

Whereas conventional techniques might take several days to narrow down the features of gravitational events from detector data, cutting-edge neural networks known as “deep convolutional neural networks” could do so within a second, the scientists found. Moreover, whereas conventional methods would need thousands of CPUs (the central processing units of computers) to perform this task, the new technique worked “even with a single CPU — that is, with your smartphone or a standard laptop,” Huerta said.

In addition, the researchers found that this new technique could also quickly analyze mergers that are more complex than current software can analyze, such as mergers involving black holes in eccentric orbits. The new software also had lower error rates and was better at spotting glitches in the data.

Huerta and Daniel George, a computational astrophysicist at the University of Illinois at Urbana-Champaign’s National Center for Supercomputing Applications, detailed their findings online Dec. 27 in the journal Physics Letters B.

How gravitational waves will change everything we know about the universe

As far as big deals in astronomy go, the confirmation of the existence of gravitational waves is likely to change our understanding of the universe in ways we never thought possible before.

After almost a century trying to prove Einstein’s theory of the existence of gravitational waves, the evidence turned out to be right under our noses.

Using the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO), one of the most powerful of its kind in the world, the faint traces of the ripples caused in space-time from cataclysmic events were recorded for the first time in September 2015, with significant fanfare.

While we can hardly describe the astronomy we have conducted for hundreds of years as ‘being in the dark’ (despite the murky depths of space), the official confirmation of gravitational waves has been described by astronomers as the equivalent of us throwing open a curtain to see how the universe really works.

A new door opens

Until now, astronomers have only been able to view the cosmos either directly using space telescopes, or by analysing objects in deep space using instruments that measure ultraviolet light.

While you, me and everyone you know creates ripples in space-time simply by, say, dancing around with another person, this rippling is practically insignificant and undetectable.

However, with major cosmic events – like the collision of two black holes, or the birth of a supernova – huge ripples expand into the universe over vast distances that, eventually, strike our planet, but very faintly.

LIGO, the L-shaped telescope, consists of two 4km, highly-sensitive laser beams that can detect even the faintest of these changes.

When a gravitational wave hits Earth, LIGO and advanced monitoring systems can detect the smallest stretching or squeezing of space-time between two points of each laser.

And so it was in September last year that such a warping of space-time was detected at a frequency of 100Hz.

This discovery allows us to throw open the door and view the first one trillionth of a second of the Big Bang.

“In short, this is a really, really difficult experiment.” Those are the words of Dr David Reitze, the man who announced to the world last September: “Ladies and gentlemen, we have detected gravitational waves. We did it.”

First steps with LISA Pathfinder

A California Institute of Technology physicist and the executive director of LIGO, Reitze was at the heart of this major breakthrough, and is one of those who will help determine where we go from here in terms of actually using the phenomenon to unlock previously-kept secrets.

Speaking with Siliconrepublic.com, Reitze spoke of how surprising the breakthrough had been in the first place, not only because it was discovered earlier than he had anticipated (he had predicted 2017), but also by how ‘loud’ the signal was.

While the reading that preceded the discovery of gravitational waves was measured at this cosmic shot of 100Hz, a typical gravitational wave measures a much lower frequency of between 0.1MHz and 1Hz.

In order to find these more elusive frequencies, we needed a very special piece of equipment called the Laser Interferometer Space Antenna (LISA) Pathfinder.

LISA Pathfinder

Developed by the European Space Agency (ESA) LISA Pathfinder was a testbed for future gravitational wave observatories and, in June 2016, recorded gravitational wave measurements five-times more accurate than anyone anticipated.

Having reached its operational orbit 1.5m km from Earth, the experimental craft internally released a pair of identical, 2kg, 46mm gold–platinum cubes.

By monitoring the smallest of fluctuations in the relative positions of the cubes, LISA Pathfinder could detect gravitational waves free of the seismic, thermal and terrestrial gravity noises that limit ground-based detectors.

“Ground-based detectors are sensitive to certain classes of astrophysical objects, particularly stellar mass binary black holes or neutron stars,” Reitze said, “but eLISA will widen the gravitational wave spectrum to be able to probe more massive astronomical objects such as intermediate-mass black holes.”

eLISA: a space project like no other

What Reitze is referring to in eLISA – the ‘e’ standing for evolved – will be a full-scale working space-based gravitational wave observatory.

With a planned launch in 2034, eLISA will be the largest instrument ever built by humanity and will act as a space-based gravitational wave detector measuring the smallest of space-time distortions.

That’s not to say there won’t be other possibilities for those without access to such a powerful device.

Even now, new research is beginning at a number of other LIGO-like observatories, including Virgo in Europe, the Kamioka Gravitational Wave Detector (KAGRA) in Japan and the recently-approved Indian Initiative in Gravitational-wave Observations (INDIGO).

This will not only help us “better pinpoint in near real-time the location of gravitational wave events in the sky,” Reitze said, but “will enable an entire new field of transient astronomy in which joint gravitational wave and electromagnetic observations of the same event can reveal vastly more than independent observations”.

With multiple observatories trawling the night’s sky both on Earth and in space, Reitze and many of his colleagues will hope that we could soon answer one of the greatest questions of our time: how did it all begin?

“The big payoff will come when we see gravitational waves produced during the Big Bang for the first time,” Reitze said. “These primordial gravitational waves carry information from the moment of Big Bang and, in fact, are the only way we can derive information from the first moments of the universe. A detection of primordial gravitational waves will be huge for the field of cosmology.”

AI in gravitational waves’ future

This huge amount of astronomical data obtained from eLISA and all the other LIGO-like observatories on Earth will require a digital toothcomb like no other.

To give an example of the amounts of data astronomers can expect to deal with, the Large Synoptic Telescope (LSST) expected to begin operations in 2019 will map sections of the night’s sky on a daily basis.

During a night’s activity, it has been estimated that the LSST will generate 30TB of images, requiring a database capable of handling 150 petabytes of storage.

This is simply more than a whole team of astronomers can ever attempt to handle manually, but now and in the future, perhaps AI and machine-learning techniques can make the entire process much more efficient.

“With its wide field, LSST will collect an unprecedented amount of image data in a very short time. Millions of astronomical objects need to be identified and classified on timescales shorter than hours.  That’s a problem that’s tailor-made for machine learning,” Reitze said.

Even now, early attempts are underway to use machine learning and the internet to help sift through huge amounts of astronomical data.

Perhaps the most famous example being SETI@Home, which allows thousands of people at home to bind together to form a supercomputer to search through data in the hope that one of its millions of users could find evidence of an extraterrestrial signal.

AI has already played a significant part in making the breakthrough that led to the recording of the September gravitational wave and will likely do so again in the future.

With so much ‘noise’ generated by the world around us, it was up to AI to help astronomers filter out irrelevant signals and hone in on the minute fluctuations that make up a gravitational wave.

This was achieved by comparing the signals in the gravitational wave channel with other channels, and the coupling of frequencies helped rule out irrelevant ones.

Author and computer scientist Michael Yuan said about the technology behind detecting gravitational waves: “With proper physics models in place, the AI could learn to fit the data against the models and quickly predict astronomical events associated with new signals.”

With another two decades before eLISA begins orbiting Earth, astronomers still have time to perfect that technology that will open a new window into the origins of the universe.
