Faster than the speed of light

Click For Summary
The discussion explores the implications of traveling faster than the speed of light, particularly regarding time dilation and the theoretical existence of tachyons, which are particles that would always move faster than light. It is noted that while the speed of light acts as a barrier in Special Relativity, superluminal speeds can occur in the context of General Relativity, especially due to cosmic expansion. The conversation also addresses the confusion surrounding observations of objects receding faster than light, clarifying that such observations are possible due to the expansion of space rather than violations of relativity. Participants emphasize the importance of context when discussing speed limits in physics to avoid misconceptions. Overall, the thread highlights the complexities and nuances of relativistic physics and the ongoing debates within the scientific community.

Well that simply goes back to my question regarding quantum tunneling. Whether or not it is a transposition of a particle, or one "wormhole-like" surpassing time.

There was another study that I can't locate regarding separated entangled electrons and their spins, in that reversing a spin of one, will also reverse that of the other. Are these electrons communicating at a certain speed, such as c, taking 1 second to change if they are 300,000km apart? Or does it surpass time, happening immediately regardless of distance? If so how, but if it takes time, and we supposedly had an atom where two electrons would be such a distance apart, what effect does it have on the atom if for 1 second the electrons in the orbital are spinning in the same direction? Then we can apply thisw to the microscopic scale, where for an unimaginably but existent small period of time, the 2 electrons spin in the same manner. Does it possibly change the interaction of one atom with another, or does anyone have an idea onto what'll happen within that period of time?

Well my own question was answered by a friend of mine. For those of you unaware, it is Bell's theorem.

It states that due to the uncertainty of the position of an electron, it could be a light year away, and not affect any delay in a reaction, Einstein calling it "Spooky Action At A Distance."
