You will find that if you previously thought you were able to create a paradox, then necessarily one of the directions of time in your “signaling” diagram disagrees with the arrow of time. Violating causality and going against the arrow of time is the same. Therefore what you are saying now is correct, but in contradiction to what you said in the blog post. You are now making the standard argument, that you deemed “complete nonsense” in your blog post. I “believe” that the present is a kind of a mirror (made out of fast-as-light particle), were faster-than-light particle and slower-than-light particle actualize. What I am saying is simply that as long as you have a consistent arrow of time, you cannot “signal” in any meaningful sense of the word.
- When the prisms are in contact, the light passes straight through, but when there is a gap, the light is refracted.
- First off, it won’t experience an immediate change in momentum or energy, as the electric and magnetic forces acting on it — which change its momentum over time — are negligible compared to the amount of momentum it already possesses.
- I think that the sun has a few billion years of life in it.
- Lentz is currently exploring existing energy-saving schemes to see if the energy required can be reduced to a practical level.
- The logical inference of this discovery is that light is a constant.
Now imagine continuous light coming from the moving spaceship. Imagine that you have a spaceship moving at twice the speed of light as it zooms past the Earth. What would this look like to a stationary observer on the Earth? Remember, that in order to see this fast object, you have to have light travel from the object to the observer .
But Faccio https://top10ten.co.uk/northern-ireland/belfast/981-1-belfast-guided-tours.html and his colleagues realized that if Rayleigh’s predictions held true, the same effect would occur in other types of waves, such as light waves. Light travels much, much faster than sound, at 670 million mph (1.1 billion km/h). And the wavelengths themselves are tiny, meaning the time reversal can be demonstrated in a normal-size room. Given the right technological advancements, is it theoretically possible for us to travel faster than the speed of light, and thus, like superman, travel in time.
Similarly, a shadow projected onto a distant object can be made to move faster than c. In neither case does any matter or information travel faster than light. In 1977, a controversial paper on Heim theory theorized that it may be possible to travel faster than light by using magnetic fields to enter a higher-dimensional space, and the paper received some media attention in January 2006.
This is just the standard argument as given by Einstein, et al. Why the heck do you see the need to tell me an utterly trivial fact of special relativity, especially after I explicitly mentioned it in my video. Seriously, why can you not at least for a second consider that I have thought about what I am telling you. Of course you can change forward and backward in time relative to some ARBITRARY coordinate time.
Breaking The Speed Limit Of The Universe
If you’re standing on the platform, a passing train might appear to be traveling at 100 miles per hour relative to you. But the train would appear stationary to a passenger on the train, provided they don’t happen to be looking out of the window. Quantum entanglement is the strange phenomena where two particles are inexplicably linked and communicate even though they may be separated by distances as far as thousands of light years. Your arguments against conventional BB cosmology have some basis in logic..

In fact, this is even easier to see in GR because most space-times have a preferred foliation already . Also, you can circumvent the problem with the negative energies if you travel faster than light by using wormholes because in this case you can use entirely normal particles. Instead of taking the long way from here to Andromeda, you could hop into one end of a wormhole and just reappear at the other end. Unfortunately, there are good reasons to think that wormholes don’t exist which I talked about in an earlier video. Say you’ve got two objects, A and B, that are moving away from point O in opposite directions.
Light always travels at the speed of light, regardless of the velocity of its source, and regardless of your frame of reference. It’s trippy and hard to wrap your head around, but it’s true. No matter how fast you throw that light, everyone in any frame of reference will clock the light coming off of it at light speed. This may all sound like science fiction, but it’s very real, and doesn’t violate the laws of physics.
Going faster than that speed, according to physics as we know it, is simply impossible. Try as you might, there’s just no way to make it go that fast. However, the satellites are also orbiting Earth about 12,550 miles above the surface. This actually speeds up GPS satellite clocks by a slighter larger fraction of a second.
The closer you get to light speed, the less time you experience and the shorter a distance you experience. You may recall that these numbers begin to approach zero. According to relativity, mass can never move through the Universe at light speed. Mass will increase to infinity, and the amount of energy required to move it any faster will also be infinite. But for light itself, which is already moving at light speed… You guessed it, the photons reach zero distance and zero time.
