Time Dilation as Future Travel
- According to Einstein's special relativity, moving close to light speed slows your time relative to someone stationary.
- This means traveling at near light speed could let you journey into the future faster than others.
Wormholes Could Enable Time Travel
- Time is another dimension like space, and physics suggests we can move through it.
- Wormholes, predicted by general relativity, could connect distant space points and potentially different times.
Wormholes' Practical Challenges
- Wormholes lack evidence and require negative energy to keep open, which we have also never observed.
- Traveling back in time with wormholes would need extreme conditions like near black holes or near light speed.
