| Mar 7 at 21:18 | comment | added | Roghan Arun | I know that the fundamental forces don't violate the speed of light rule but what about quantum tunneling? What if a photon tunnels from a flashlight to a spot one light year away and then there happens to be a detector one light year away?Wouldn't there be a measurement which can be stored until the person reaches the measurement device? | |
| Mar 7 at 6:59 | comment | added | safesphere | Both gravitational and electromagnetic interactions are instantaneous, but this does not mean that gravity or electromagnetism propagates faster than light and does not allow the superluminal transfer of information. For example, the Earth is pulled by the Sun toward the actual position of the Sun in the sky 4 Sun’s diameters ahead of where we see the Sun with the 8-minute delay for the speed of light: physics.stackexchange.com/questions/364427 - arxiv.org/abs/gr-qc/9909087 - physics.stackexchange.com/questions/492870 | |
| Mar 7 at 6:46 | comment | added | safesphere | You may find this study interesting: bigthink.com/starts-with-a-bang/hawking-radiation-black-holes - It claims the horizon is not needed, compares the Hawking radiation to the Schwinger effect in electromagnetism, and explains that most radiation is created at 25% above the Schwarzschild radius. The latter is because the radiation is proportional to the tidal forces that fall as the third power of the radius, but the time dilation that affects the energy depends on the distance to the horizon. Combining both formulas explains the result. | |
| Mar 7 at 6:31 | comment | added | Ghoster | information can be sent faster than light through this process No. When you reach that conclusion, it means that you’ve reasoned incorrectly. This is non-mainstream physics, and a personal theory, and both are off-topic here. | |
