when you travel 25,000 miles an hour in space for 1 year straight how much time will go by on earth?

Question

while your traveling you never stop or slow down.

Answer 1

There would be no significant difference in time between someone on earth and on a spaceship. 25,000 mph is the speed required to leave earth's gravitation field. Some of the spacecraft that have been sent to the outer planets and beyond are traveling at 36,000 miles per hour. Time dilation only occurs to a significant amount when you are traveling near the speed of light which is 669,600,000 miles per hour. The speed you mention is not even 10% the speed of light.

Answer 2

It will still be about a year, since 25,000 mph is nowhere near the speed of light. If you do the calculations in the denominator of the time dilation equation: Square 25,000, then divide by c^2 (in mph), subtract it from 1, then take the root of it. It'll be extremely close to 1.

Answer 3

I don't know the exact number but, according to Einstein's Theory of Relativity, the faster you go, the slower time moves for you. A test was conducted with a plane that flew around the world, I think, and the time was a millionth of a second off. I'm thinking that maybe a couple of days more than a year would have gone by. Like I said, I don't know the actual number.

Answer 4

The equation for this is Δt = ∆T * sqrt(1-v^2/c^2)

Where ∆t is the amount of time experienced by a stationary object, ∆T is the amount of time that is experienced by the moving object, v is the velocity, and c is the speed of light.

So, this give us:

Δt = 1 year * sqrt(1-25,000 mph^2/670,635,729 mph^2)
Δt = 0.9999999993 years.

In other words, the difference in the amount of time experienced by the moving object as opposed to something sitting at rest is 0.02 seconds.

Answer 5

Several Decades would have passed,
when you return. You will find a new earth
with no acquintances around.

This question is based upon the
Great Theory of the Relativity
of Albert Einstine, the greatest
physicist.

The speed of light and outer
space is a wonderful subject and
is mind boggling.

186000 miles per second X 1 day
x 12 months and a space clock
in the Space shuttle will give you
the details of years passed on the
earth on return.

Answer 6

One year. It is only as one approaches the speed of light that time slows down according to Einstein's theory of relativity. The speed of light being something like 669,600,000 mph, 25,000 mph isn't enough to make a measurable difference.

Answer 7

You're apparently looking for the relativistic time dilation effect?

OK, the answer, using sqrt(1-(v/c)^2) is:

1 year+22 milliseconds.

The reason is that 25,000 mph may sound fast, but it's only about 7 mi/s, while speed of light is 186,000 mi/s.

Answer 8

It depends where on Earth you mean! At the poles or at the equator! At the top of Mt. Everest or at the bottom of the Marianas trench! It depends on your height! It depends on the thickness of your shoes! It depends on whether you have wavy hair or are bald! Are we talking nominal or what? It depends where the Earth was at the time you left the Earth,was it at apogee or not? There are many varibles to take into account when you answer this one!

Answer 9

About a year and 1/1000 of a second. 25,000mph isn't fast enough to get much time dilation.

Answer 10

it has been proven scientifically that traveling in space you dont age as fast as you do on earth. This is tought in modern physics I think they showed us how but that was college 15 years ago.
