One application I can think of is that if I had an incurable disease I could go on a one week ride in a spaceship, on return 50 years have passed on earth. Of course if there wasn't a cure I could just go on another trip.

Quite possible, though not a week. Even if we had a starship that could go 0.9999999c you'd still need to accelerate to that speed at an acceleration that wouldn't kill the crew. Unfortunately us flesh bags can only stand around a couple g's for extended periods of time so it'd take quite a while to get up to speed.dshea said:One application I can think of is that if I had an incurable disease I could go on a one week ride in a spaceship, on return 50 years have passed on earth.

EDIT: I guess the term I'm looking for is human cryonics.
Einstein's theory of relativity states that time is relative and can be affected by an object's speed and gravity. As an object's speed approaches the speed of light, time slows down for that object. This means that as we approach the speed of light, time travel becomes possible as we can travel to the future at a faster rate compared to someone who is stationary.
According to Einstein's theory of relativity, objects with mass cannot travel at the speed of light. As an object's speed approaches the speed of light, its mass increases infinitely, making it impossible to reach the speed of light. However, we can get close to the speed of light, which would still result in time dilation and allow for time travel.
Einstein's theory of relativity also affects space travel as it explains the concept of space-time. As an object's speed increases, it experiences time dilation, which means that time passes slower for that object compared to a stationary object. This also affects the distance traveled, as the faster an object travels, the shorter the distance appears to be.
No, according to Einstein's theory of relativity, faster-than-light travel is not possible. As an object's speed approaches the speed of light, its mass increases infinitely, making it impossible to accelerate to the speed of light. Additionally, as an object's speed increases, the energy required to accelerate it further also increases, making it impossible to reach the speed of light.
Einstein's theory of relativity has greatly impacted our understanding of the universe. It explains how gravity works and how space and time are intertwined. It also allows for the possibility of time travel and has been used to make predictions about the behavior of objects in the universe, such as black holes. Overall, it has revolutionized our understanding of the universe and continues to be a fundamental theory in modern physics.
