Wait...its giving birth to stars, that are only a few million years old? Well, how do they know that its the one making them? Last i checked, humans werent around a few million years ago, so who would they possibly know this thing is the cause of them???

When we look into outer space, we're actually looking back in time. Some of the stars that you see in the sky have already died out, but since it takes so long for their light to travel to earth, we're actually seeing them as they existed millions of years ago. So when we look out in the sky, we can actually see a star being created, as if it were happening today, even if it happened millions of years ago.

LMAO! I never knew shit about space and time either. I just picked up Astronomy for Dummies two months back. It's a pretty easy read if you don't know anything about space.

ralphie may on joe rogan podcast breaks down stars and "time travel" and such yall should peep it. he basically says if we went light years away from earth and had a powerful enuff telescope we can see the past as it unfold. pretty mainy stuff.*passes blunt*

If you are interested in learning more I would highly recommend "The Fabric of the Cosmos"

It is the best book I have read on space-time, general relativity, special relativity, theoretical physics, string theory, cosmology, etc, etc.

i never watch the sci channel but the other night that hawkins guy had time travel show on and it was talking about how once you hit the speed of light you are going into the future basically

if someone was in a train going close to light speed for so long ( i forget) when they stop it could be 100 years for everyone else but only two weeks for them

It's also interesting to note;

Special relativity incorporates the principle that the speed of light is the same for all inertial observers regardless of the state of motion of the source
Meaning that if you are traveling, 300,000 miles an hour and you shine a light in the same direction you are traveling, it will travel away from you at the speed of light - even though you are already traveling in that direction at 300,000 mile an hour.
