Does time slow down as speed increases?

Answer 1

yes. and then again, no. try reading some Einstein, getting a physics degree and then you still won't be able to understand. but, I'll try to explain. if you are the one travelling at the speed. no. if you're not, yes. sorry best i can do without a 15,000 word essay.

Answer 2

If you go whizzing past me at a high speed, then I'll notice that your wristwatch

looks like it's running slow, and the pitch of your voice has dropped. I'll think to

myself, "Hey ! I'm OK, but his time has slowed down."

At the same time, you'll notice that my wristwatch looks like it's running slow, and

the pitch of my voice has dropped. You'll think to yourself, "Hey ! I'm OK, but his time

has slowed down."

We'll both be correct.

Another contributor added:

When something goes past you at high speed, it takes longer for the light bouncing off of that thing to reach the observer. This also goes in reverse, say, if you are traveling at high speed and you see that someone standing still has slowed down. To the observer (you) the person standing still is traveling away from you and you are standing still.

This doesn't mean that after the traveler stops, everyone's time will be back in synch. If you start off on earth and accelerate to near the speed of light and you travel for a significant length of time according to earth observers, when you return LESS TIME will have passed for you; you will be younger (relative to your velocity and time away) than the twin brother you left on earth. You will literally have experienced less time.

Answer 3

According to the theory of special relativity, time dilation occurs as speed increases. This means that time appears to move slower for an object in motion compared to one at rest. This effect becomes more pronounced as the object approaches the speed of light.
