This one is likely a hard question. If you put one half of an entangled pair on a space ship going fast enough for time dilation to set in, could time travel be possible?

This is indeed a complex question, and unfortunately, the answer is no. While the concept is fascinating, entanglement and time dilation don't directly lead to time travel.
Here's a breakdown of why:
Entanglement: Entanglement is a quantum phenomenon where two particles become inextricably linked, sharing properties instantaneously, regardless of the distance between them. However, entanglement doesn't allow for sending information faster than the speed of light, which is a fundamental limitation in the universe.
Time Dilation: Time dilation is a consequence of Einstein's theory of relativity. It states that time passes more slowly for an object moving at a high velocity relative to a stationary observer. While a traveler on a fast spaceship would experience time passing more slowly compared to someone on Earth, they wouldn't be traveling backward in time.
Why it's tempting to think so:
The allure of connecting these two concepts lies in the fact that they both seem to defy our everyday understanding of space and time. However, the mechanisms behind them are fundamentally different. Entanglement involves the strange interconnectedness of quantum particles, while time dilation is a consequence of the geometry of spacetime.
Current Research:
While time travel remains firmly in the realm of science fiction, research into the implications of entanglement and time dilation continues to push the boundaries of our understanding of the universe.
Let me know if you'd like a deeper dive into either entanglement or time dilation!
