decelerated aging whilst traveling at the speed of light?

Question

i have been told that if one were to travel at the speed of light, one would age ( realitive to people not traveling at the speed of light ) much slower. in fact there is a popular anecdote explaining this, a twin brother gets on a space ship that travels at the speed of light , and upon returning moments later, his sister is an old woman.

ok, it defies all intuition about the nature of time to say that your physical movement through space effects the passing of time. if 3 seconds have passed, it shouldnt matter how fast you were traveling during that time, you still just 3 seconds older. but apperently i dont understand something. help me!

Answer 1

While it has not been ever tested we cannot find this question out, but I do believe that if you travel at 50 mph for 30 second and come back at the same speed, would your dog be 60 secs older or 62?

Answer 2

It's a difficult concept to grasp, because it doesn't seem to make sense on the face of it, does it? Probably the best way to get an understanding of why it (supposedly) would work that way is to read some of the science fiction that deals with time travel. In a story form, with a good author, you get to absorb the science in a pleasurable form.

"Time For the Stars" by Robert A. Heinlein is (in my opinion) one of the best at explaining while entertaining. The story is very much like your anecdote -- twin brothers, one who stays on Earth and another who travels in space.

Answer 3

Nowadays, a twin brother could get on a space ship and come back finding that his brother is now an old women.

Seriously, this is Einsteinian relativity, the relation of time to velocity relative to the speed of light.
time = k (v^2/c^2). Of course, we haven't been able to transport anything the size of a person at a high velocity, so while the concept of time slowing is reasonable, its effect on a biological being, which you are really concerned about, is not proven. Of course, relativity doesn't address biological consequences.

Answer 4

The "speed" isn't the subject so as plenty simply by fact the 'acceleration" to realize it. the gap holiday generates approximately 3g in the time of launch; and people can tolerate as much as 9g for a quick era. long tale short -- it would require months of continuous acceleration in the obstacles of human tolerance to get close to the linked fee of sunshine. and then there is the entire rely of a gas source,..., blah, blah, blah Jesus did not even understand approximately electrical energy or indoor plumbing, so that is uncertain he substitute into carrying out any experiments regarding the linked fee of sunshine.

Answer 5

Non -sense..
