I just caught that last guy in a huge error, he said this wave of energy was coming from the center of our galaxy and would take 22 million years to
reach us at the spend of light. Uhhh the galaxy is only 100,000 or so light years across so what he just said was WRONG.
Say the galaxy is a gigantic treadmill and you are light. If the gigantic treadmill is moving toward the center of the galaxy at 10 mph and you are
running away from the center of the galaxy at 8 mph, how long will it take you to go 100,000 miles?
Now, even more accurately, imagine the galaxy is a gigantic treadmill that is moving. At the center of the galaxy, the treadmill drops off and goes
under at the event horizon. Right at the event horizon, the treadmill is going at an incalculable speed. The further away from the center of the
galaxy, the slower the treadmill is going. Now imagine you started at the center of the galaxy and ran towards the outside of the galaxy. How hard
would you have to run your ass off before you finally broke away from the center enough to even gain a calculable difference in distance? Sure, after
you finally broke away well enough, you'd gain speed, but now imagine that the treadmill is not only moving towards the center, but that the whole
treadmill itself is spinning. Now, let's see you keep your current vector and keep your speed up!!!
A light year means a light year in perfect conditions. We all know that light has a harder time getting away from a black hole. In fact, I'm
intrigued by that guy's statement because most people would forget this kind of thing and would go solely on common knowledge (i.e.- the galaxy is
100,000 light years across...).
Now, I didn't look up the distance from the center of the galaxy to earth, but I'm guessing that it probably takes light a decent amount of time
just to get away from the center of the galaxy.
I noticed that I made an interesting error according to my own thinking. In the first example, change the speeds around. You are running at 10 mph
and the galactic treadmill is moving inward at 8 mph, so to speak. I think my original statement might be more accurate for an object caught into the
event horizon...? Feel free to correct me (as I am sure someone will).
