In essence how does time travel relate to space?

In summary, the possibility of looking back at yourself traveling to Mars is dependent on the existence of the right method of time travel. There is a theoretical possibility of this with the assumption of faster-than-light travel and application of Lorentz transformations, but it raises concerns about causality. Some argue that causality can be violated through quantum entanglement, but this is a topic currently under moderation.

So basically if you were on Mars, you cool look back and see yourself traveling to mars?

With the right way of time travel (if this is possible), this would be possible.

If we could just figure out the "right way".

I'm confused into how this theoritically would be possible?

I think that was mfb's point.

If you assume FTL travel and applied your lorentz transformations you would find that you arrived at your destination before you actually left and you can visualize this better if you plot it on a space - time diagram. It is however a violation of causality.

Thread locked temporarily pending Moderation...

isnt causality actually brought down by quantum entanglement which effect its been verified to be instantaneous happening cause and effect at the same time?
 

1. What is the relationship between time travel and space?

Time travel and space are intricately linked in the concept of spacetime, which is a four-dimensional continuum that combines the three dimensions of space with the dimension of time. This means that any movement through space also involves movement through time.

2. How does time travel affect the laws of physics in space?

The laws of physics remain consistent in both time and space, regardless of whether time travel is involved or not. However, the effects of time travel on space may lead to paradoxes or alternate timelines that challenge our understanding of the universe.

3. Can we travel through time without also traveling through space?

No, due to the nature of spacetime, any movement through time also involves movement through space. This is because space and time are inseparable dimensions, and one cannot exist without the other.

4. How does the theory of relativity explain the relationship between time travel and space?

The theory of relativity, proposed by Albert Einstein, explains the relationship between time travel and space through the concept of spacetime. According to this theory, the fabric of spacetime can be bent or warped by massive objects, which can then affect the flow of time and the movement of objects through space.

5. Is time travel possible in our current understanding of space?

While time travel has been a popular topic in science fiction, it is not currently possible according to our current understanding of space and time. The laws of physics, particularly the principle of causality, make it improbable for time travel to occur without causing paradoxes. However, ongoing research and advancements in our understanding of the universe may eventually lead to a better understanding of time travel and its potential feasibility.
