what is the difference between time dilation and time travel?
Answers
Answer:
Time dilation and time traveling are completely different concepts, in the sense : time traveling : AS i know it , it is a hypothetical phenomena which involves in moving frome one space-time to another , it also includes moving to a different time from the starting point (future or past) irrespective of speed or mass of the object moving.
time dilation: using a very famous exapmle as i remember it of twin , one of the twin takes off from the Earth with the speed of light ,and returns say after one year . for the twin who took off , time remained constand and when he returns ...he will be a year younger than the twin who stayed . (relativity)
Time dialation is just slowing of time(like we will feel 1sec as more than 1 sec), when we move really fast like near the speed of light but, time travel means moving back in time or vice versa. It is known as time distortion and it can happen when one moves faster than light which is not possible.
