I love reading about outer space.It will completly blow your mind.I mean the speed of light is something around 140,000 miles per second.Thats right, I said a second.
Black holes are also very interesting to learn about.The force of gravity is so strong in them because it is like shoving the mass of ten of our suns into the same space as the earth and the sun is like seven times the size of the earth.(those numbers are not exact but you get the idea).Their force of gravity will suck in anything around them including light.Now thats crazy,so much gravity that it sucks in light.Black holes will also distort the time around them.Meaning there is an area around the black hole where if you could orbit in that area time would actually slow down.Everything is relative you know.

Actually, the moon is getting farther and farther away from the earth. It's also interesting to know that as the moon drifts away, the earth's days are getting longer because of it. It has to do with circular motion, but it's kind of cool that we can actually calculate almost exactly the effect the moon has on our days. I'm a huge nerd, sorry.
But in 100 years it will only be 2 milliseconds longer.
You are right about it getting farther and farther away...I knew that too, I don't know why I said closer and closer. My bad. I saw a documentary on this not too long ago about the effects of the moon.

Yeah, it's insane to realize exactly how gifted Einstein was. He predicted that gravity bent light well before anyone had any experimental evidence to prove so.
It wouldn't take long for his theory to be put to the test, because according to Einstein during a solar eclipse, we would see that the stars observed behind the sun would be out of position in relation to where the stars should be from previous observations.
Sure enough, during the solar eclipse, it was observed that the star near the sun was actually observed to be closer to the sun than it should have been.

That is nuts. I've never seen that before.
Cool shit.

I just don't see how this can work. I saw previews for this, saying it would take like 3 months to travel on it.
Speaking of, do you plan on seeing this?

Space Week rocks, I wish they would release all of those as a DVD collection. Have you been watching it?

I think this is the most efficient way to transport cargo outside of our atmosphere. An achievement like this could change the world as we know it. Currently, I think the cost of space transport is about $10K per pound (please correct me, if I'm wrong). With something like this, it could be incredibly cheaper -- making space exploration and development much more feasible. I could see this happening within the next 20 years.

Not as much as I would like
The one about the sun was very cool, and I watched a few last night, one about Mars and another one about Saturn. Saturn was very interesting.
