# If the faster I go, the slower time becomes for me, then does that mean the slower I go the faster time becomes?

Disclaimer - I’m not a trained physicist. I just have an interest in the subject so this question is probably going to come across really confusing but I’m trying my hardest to explain.

So firstly, this is my assumption of how time dilation works. So say, you travel in a spaceship at almost the speed of light for one day. You might only spend 1 day at that speed, but because time passes slower for you than people on Earth, so then that 1 day is actually 10 years in Earth time and when you might come back, everyone is 10 years older while you’ve only aged a day.

So given this, how would I achieve the opposite? How could I slow myself down in comparison to everyone else on Earth that me spending 10 years at that speed is actually only 1 day for everyone else?

I ask because there really isn’t an absolute velocity that everyone is travelling at right? We are stationary right now but the Earth is moving around the Sun which is moving around the Milky Way and who knows where that’s orbiting. How can I go slower than how fast I’m travelling currently?

• It is not about absolute speed, but about relative speed, and both see that the other observer's clock is slower. Only the observer that has to accelerate/decelerate ends up "younger". And you cannot easily accelerate earth like you do with a spaceship. See en.wikipedia.org/wiki/Twin_paradox – user126422 Mar 13 '17 at 14:27
• If you move away from Earth at a specific speed, and then you turn around and return to Earth at that same speed, and in turn age only 1 day compared to Earths 1 year, three things could have happened. 1) Time slows down for you and equally so in both directions. 2) Time for you sped up on your trip away from Earth, but slowed down on you return trip. 3) Time for you slowed down on your trip away from Earth, but sped up on your return trip. other. – Sean Mar 13 '17 at 22:30
• I forgot to mention - I did the calculations and found that the 1 day outcome occurs in all three cases, so there is no way to tell which of the three events had occurred. ( disregard word "other" at end. it's an edit booboo.) – Sean Mar 13 '17 at 22:37
• @sean what about instead of going somewhere and back, you just did orbited the earth at the increased speed – RoboShop Mar 14 '17 at 6:23
