17 Φεβ 2000 · Time travel has been a staple of science fiction. With the advent of general relativity it has been entertained by serious physicists. But, especially in the philosophy literature, there have been arguments that time travel is inherently paradoxical.
- Quantum Mechanics: Retrocausality
In Bohmian mechanics the dynamics is time-symmetric, but the...
- Quantum Mechanics: Retrocausality
Relativity means it is possible to travel into the future. We don't even need a time machine, exactly. We need to either travel at speeds close to the speed of light, or spend...
Time travel to the past is theoretically possible in certain general relativity spacetime geometries that permit traveling faster than the speed of light, such as cosmic strings, traversable wormholes, and Alcubierre drives.
26 Απρ 2023 · According to Einstein’s special theory of relativity, time’s flow depends on how fast you’re moving. The quicker you travel, the slower seconds pass. And according to Einstein’s general...
24 Φεβ 2024 · General relativity might also provide scenarios that could allow travelers to go back in time, according to NASA. But the physical reality of those time-travel methods is no piece of cake.
11 Οκτ 2024 · How do we know that time travel is possible? More than 100 years ago, a famous scientist named Albert Einstein came up with an idea about how time works. He called it relativity. This theory says that time and space are linked together.
17 Φεβ 2000 · Time travel can occur in general relativistic models in which one has closed time-like curves (CTC's). A time like curve is simply a space-time trajectory such that the speed of light is never equalled or exceeded along this trajectory.
