Hypothetically, if someone did manage to develop a faster-than light spaceship (like Star Trek), you would be able to look back through a powerful telescope and see yourself launching from Earth. “In our theory, if you go back to the early universe, there’s a temperature when everything becomes faster. Pertinence. Log in Sign up. 11 réponses. « Last Edit: 16/06/2017 11:38:30 by puppypower » or Perhaps there is another way, suggests Magueijo. “Light sources, however, may move faster than the speed of light when their speed is not associated with the physical motion of matter. Faster Than Light Beyond the expansion of the universe, several other theoretical and observed phenomena are thought to be faster than the speed of light. Then, when I look at my original correlation matrix (not the PCA matrix's) I see that these two variables correlation is, in fact, only moderate at best. Of course, light is even faster. For generations, physicists believed there is nothing faster than light moving through a vacuum — a speed … The duo tested this idea against the universe’s Cosmic Microwave Background (CMB), which is the radiation created shortly after the Big Bang that fills the universe. Gravity. faster. Jason Daley is a Madison, Wisconsin-based writer specializing in natural history, science, travel, and the environment. But this idea is often criticized because it requires the creation of a set of conditions that would only exist in the universe's infancy—something that cannot be easily tested. This fixes a value called the spectral index, which describes the initial density ripples in the universe, at 0.96478—a value that can be checked against future measurements. Where do they get their charge from? But what if we switched the rules a little? An electromagnetic wave requires a powerful transmitter and huge receiving antenna antennas to bridge the distance. Recently scientist discovered neutrinos traveling faster than the speed of light. If we can fly faster than speed of light, could we see images of past in space? Speed of light is constant. Faster-than-light (also superluminal or FTL) communications and travel are the conjectural propagation of information or matter faster than the speed of light.. 17th Annual Photo Contest Finalists Announced. I loved reading this news article: Was the Speed of Light Even Faster in the Early Universe? What is your view? Atoms are neutral while electrons and protons are charged particles. Hypothetically, if someone did manage to develop a faster-than light spaceship (like Star Trek), you would be able to look back through a powerful telescope and see yourself launching from Earth. Terms of Use How I should structuring my input data. Einstein and his partner, the Dutch astronomer Willem de Sitter, admitted only one way this could happen: with repulsive gravity. Travelling thousand times faster than the present speed of light should be possible, and require less energy than a spaceship who has reached 90 percent of the 300 000 km per sec of today. Privacy Statement Suddenly there was talk of all kinds of bizarre concepts, from time travel to parallel universes. But why does that matter? shares. You would be seeing what for you is the present in your immediate surroundings. For example, if you point a laser dot at an extremely distant object you can move the laser such that the dot will move faster than light. I know that some statisticals test exist but I don't know which one I should use. This is light energy released as these particles spontaniously cease to exist as particles! The varying speed of light theory solves some of the most intractable problems in cosmology, and could have major implications for the study of physics. And what if the speed of light was a million times faster than it is today, instead of much slower. Now my question: Why does model.predict() in keras produce the same output for any input when training a LSTM? Faster-than-light (also superluminal or FTL) communications and travel are the conjectural propagation of information or matter faster than the speed of light.. His work has appeared in Discover, Popular Science, Outside, Men’s Journal, and other magazines. Theoretical physicist Magueijo presents the idea that light traveled faster in the early universe than it does today. We would see this impact in our sediment layers and … A common young earth argument for a young earth is that the velocity of light has been decreasing exponentially since the creation of the universe. If the speed of light is current time, wouldn't traveling faster than it only bring you in front of current time and not behind it, which would bring you into the future? Nov. 5, 2018 — Scientists have produced an extremely bright spot of light that can travel at any speed -- including faster than the speed of light. Interesting query. 340 meters per secons. Light travels at a blistering 670 million mph — a speed that’s immensely difficult to achieve and impossible to surpass. What happens to radiation trapped inside the Faraday cage? The speed of light was known to be about 186,000 miles per second, so the orbital speed of the Earth is about .01% the speed of light. This thread is archived. One of the key insights that Albert Einstein used to develop his theory of relativity was that light in a vacuum always moves at the same speed. You would see all the photons from the past in rapid succession so that remote objects would approach the present of the traveller heading toward them. hide. Is it true to make the input as (m,n,1) and output targets as (m,L)!. Some say that when finish conv, it will generate 3 feature maps when the sample is RGB,and then 3 feature maps will add up and turn into 1 feature map.What is the process mean. reberac. These exceptions involve exploiting the properties of waves and are both theoretical and actually observed. Why is it that traveling faster than the speed of light would take you to the past, and not to the future? If a person could travel faster than the speed of light,would he go into the past? It's a well established fact that nothing can travel faster than light, so as a speed limit it cannot be broken. So if you change the speed of light you would also have to change how strong the electric and magnetic forces are. To understand how waves allow this apparent break in the laws of physics, imagi… This isbecause, in the past, the speed of light would have been much faster, meaning thatlight would have traveled much farther, making the universe appear old eventhough it were young. If speed of light was 1 mile per second then thats what the speed of light would have been. Write. According to some scientist when something reaches to 99.99% of light and if it tries to accelerate further to attain the velocity of light it starts traveling in time and time slows down for it so as it could not travel faster than the light as it is the speed limit and you have to follow traffic rules.

Most watched News videos. Moving at the Speed of Light . When training a CNN,how will channels effect convolutional layer. If the shell observer could sit at the event horizon (they can't without an infinitely powerful rocket) they'd see the stone pass at the speed of light. Suddenly there was talk of all kinds of bizarre concepts, from time travel to parallel universes. The Markarian galaxy no.501 has been observed on a series of plates taken between years 1967 and 1976 at Asiago Observatory. This may all sound like science fiction, but it's very real, and doesn't violate the laws of physics. *BONUS more subjective (and hard) question:*. The decoder is trained as a language generative model with the key-phrases as input and the next word as output at each time-step. To explain this discrepancy, physicists developed the inflation theory, which suggests that the early universe was much smaller, allowing temperatures to even out. The speed of light. “Many scientists regard inflation as a simple and elegant explanation of the origin of galaxies in the universe.”. Since most nuclear processes are mathematically related to the speed of light, a faster ‘c’ might well mean a faster rate of radioactive decay, thus explaining much of the evidence used to justify the billions of years of geological hypothesizing. Log in Sign up. Based on the researchers model, the CMB acts as a sort of timeline for universe fluctuations, recording how the speed of gravity and the speed of light change with variations in temperature, reports Michael Brooks at New Scientist. At the opposite, the specialist may elaborate and check the consistency of any new theory on the speed of light. The shell observer sees the stone fly past at a velocity less than the speed of light, and the nearer the shell observer gets to the event horizon the faster they see the stone pass. According to some scientist when something reaches to 99.99% of light and if it tries to accelerate further to attain the velocity of light it starts traveling in time and time slows down for it so as it could not travel faster than the light as it is the speed limit and you have to follow traffic rules. An energy beam that stabs out of galaxy M87 like a toothpick in a cocktail olive is pulling off the ultimate magic trick: seeming to move faster than the speed of light. These strings feature a fixed emission duration that does not depend on the frequency of the photon. From the perspective of someone on Earth they are seeing the past, but no matter how fast you travel their past is not yours. It was a claim that contradicted more than a hundred years of scientific orthodoxy. https://www.smithsonianmag.com/smart-news/was-speed-light-even-faster-early-universe-180961233/, New Light on the Structure of the Galaxy Gained in 1952, The optical variability of the galaxy Markarian 501, The Effect of Possible Errors in the Light Extinction on the Determination of the Parameters of the Spiral Structure of the Galaxy. Advertising Notice Join ResearchGate to find the people and research you need to help your work. 75% Upvoted. Il y a 1 décennie. But now it is debunked. The object shows a slow variation on light between the B magnitudes 13.6 and 14.5 with a probable minimum on the years 1972-1973. In September 2011, an international group of scientists has made an astonishing claim - they have detected particles that seemed to travel faster than the speed of light. If going faster than the speed of light is how one could conceivably travel into the past, what measurable of speed must an object be slower than to achieve travel into the future?
