What goes up but never comes down but slows up if you travel to outer space?

Answer 1

in order for time (which I think is the answer you're looking for) to "slow up" (or "slow down", rather), you'd have to be going pretty darn fast:

"As the speed of any object increases, its properties, as measured by an observer at rest, change. Its mass increases, its length in the direction of travel decreases and time slows down. At ordinary Earthbound speeds, even those of a jet plane, the changes are infinitesimal.
At very high speeds, however, the changes become extremely important. An astronaut travelling at 90 per cent of the speed of light, for instance, would not feel any different from his twin on Earth. But the mass of his spacecraft would be more than double, its length would be less than half and a clock on board would take an hour to record 25 minutes because time had slowed - and he would therefore be ageing at less than half the speed of his brother.
At the speed of light, the mass of his spacecraft would become infinite, its length would shrink to nothing and time aboard it would slow to a complete stop. Since this is impossible, nothing, other than light, can travel as fast as, nor faster than light."

but it really only APPEARS to "slow up":

"The twin paradox: It's all relative(s)

Einstein came up with an example to show the effects of time dilation that he called the "twin paradox." It's a lot like the Time Traveler game you just played. Let's try it out with a pair of pretend twins, Al and Bert, both of whom are 10 years old in their highly futuristic universe.

Al's parents decide to send him to summer camp in the Alpha-3 star system, which is 25 light-years away (a light-year is the distance light travels in a year). Bert doesn't want to go and stays home on Earth. So Al sets out on his own. Wanting him to get there as quickly as possible, his parents pay extra and send him at 99.99 percent the speed of light.

The trip to the star and back takes 50 years. What happens when Al returns? His twin brother is now 60 years old, but Al is only 10 and a half. How can this be? Al was away for 50 years but only aged by half a year. Has Al just discovered the fountain of youth?

Not at all. Al's trip into space lasted only a half year for him, but on Earth 50 years passed. Does this mean that Al can live forever? Nope. He may have aged by only half a year in the time it took 50 years to pass on Earth, but he also only lived half a year. And since time can slow down but never goes backwards, there's no way he could grow younger."

Answer 2

Gravitational time dilation states that factor is going slower in bigger gravitational fields. the way i see it (please spectacular me if i'm incorrect) is that a community of area without gravity could retract whilst extreme gravity is unexpectedly latest. Therefor in case you have been in area, you may witness a similar section frames of area being retracted close to Earth. to place it much less complicated, in the adventure that your physique in area grew to become right into a million kilometre long and you travelled at a million kilometre an hour, of course you may commute the area in a million hour. Your chum on earth could witness precisely a similar concern together with his physique. a million kilometre long, a million kilometre an hour. the version between the two separate frames from a 0.33 attitude is that the physique close to Earth has slightly retracted (reduced in size or bent), which contains the human (the human has been born right into a community of gravity, technically the only in area could boost). meaning that the two people does no longer be conscious something diverse however the cases could be. you may desire to undergo in ideas a number of issues that folk forget. a million: Clocks are synthetic and sturdy therefor they gained't retract with area as area is merely vacuum. people interior the area station strengthen taller as much as six centremetres each twelve months (approx). 2: area suits are worn by way of people, if no longer the human could boost and clearly die. Spacesuits are greater dense than area. 3: each thing retracts in the direction of gravity why could area be diverse? a guy on the age of 18 is taller than years later whilst he's eighty one. we are experienced to renowned that he shrinks with age yet why? via fact gravity over the years has retracted him. wish that's smart as that's a complicated subject rely to talk approximately. you will locate greater in concept of Relativity.

ur age...duh
