Now Playing Tracks


after my procedure at the hospital today my doctor tried to explain all of the medications he’s putting me on and i was kind of out of it on pain meds and he goes, “and i’m going to be putting you on some serious steroids, do you have any problems with that?” 

and apparently i looked at my mom and whispered, “i’ll never play major league baseball” and started crying

Why isn’t it possible to time travel?

Actually, it is possible to travel into the future. Of course, we’re all moving into the future at the “regular” speed. But if you want to move into the future at a rate faster than everyone else, you simply need to move (physically) very, very quickly. Because of the time-dilating effects of Relativity, the faster you move, the slower time will flow for you. Moving sufficiently quickly would allow you to travel hundreds or even thousands of years in the future (while you remain young).

However, taking this concept of time dilation to its logical conclusion, if you were to travel at the speed of light, time would stop. And, if you were to travel faster than light, you would travel backwards through time. That’s not possible though because (again, due to the effects of Relativity) as you approached the speed of light, your mass would approach infinity which would require an infinite force. An infinite force cannot exist. So, as far as we can tell, you’re stuck moving forwards through time.
