Does information travel faster than light

In summary, the conversation discusses the concept of signals traveling faster than light and how it relates to Einstein's theory of relativity. While some experiments have shown the possibility of these signals, they are considered "hidden influences" and do not violate relativity unless they can be used for communication faster than light. Mainstream science has chosen to preserve microcausality and reject the idea of faster-than-light communication, instead explaining quantum correlations as arising from outside of spacetime.

Usable or not this seems to be a spooky statement can this 10000 be falsified?.

Experiments have already shown that if you want to invoke signals to explain things, the signals would have to be traveling faster than light -- more than 10,000 times the speed of light, in fact. To those who know that Einstein's relativity sets the speed of light as a universal speed limit, the idea of signals traveling 10,000 times as fast as light already sets alarm bells ringing. However, physicists have a get out: such signals might stay as 'hidden influences' -- useable for nothing, and thus not violating relativity. Only if the signals can be harnessed for faster-than-light communication do they openly contradict relativity.

Look at https://www.physicsforums.com/threa...-bohmian-mechanics.899967/page-2#post-5664597 from a parallel thread, where the same choice that the article you linked presents in a confusingly hyped mode is spelled out. Mainstream science in the form of QFT has already chosen to discard FTL communication and preserve microcausality, and what is sensationalistically described in the article as "that quantum correlations somehow arise from outside spacetime, in the sense that no story in space and time can describe them" is formalized with this microcausality that has spacelike separated operators commute and therefore being causally independent.

1. Does information really travel faster than light?

No, according to the theory of relativity, the maximum speed at which any object or information can travel is the speed of light, which is approximately 299,792,458 meters per second.

2. Can anything travel faster than light?

As of now, there is no evidence to suggest that anything can travel faster than light. The speed of light is considered to be the ultimate speed limit in the universe.

3. What about quantum entanglement? Doesn't that allow for instantaneous communication?

Quantum entanglement does not allow for instantaneous communication. While two entangled particles may seem to communicate faster than light, they are not transmitting information. Any changes in one particle are random and cannot be controlled or used to transmit information.

4. Is there any evidence of anything breaking the speed of light barrier?

No, there is no scientific evidence of anything breaking the speed of light barrier. Some experiments have shown particles appearing to travel faster than light, but these are usually due to experimental error or misinterpretation of the data.

5. What would happen if something did travel faster than light?

If something were to travel faster than light, it would violate the laws of physics as we currently understand them. It would also lead to a breakdown in causality, as an effect could occur before its cause. This would have significant implications for the fundamental laws of the universe.
