I was reading some facts about the Universe, and I cant wrap my mind around how huge it truley there are more stars in the sky then there are grains of sand on earth. The sun is 3300,3300 times bigger then the earth. Or something like that. I mean WOW!! It said if you took all the matter in the universe, and compared it to all the space it would be like a grain of sand in a room 20 miles tall 20 miles wide, and 20 miles long. It allmost dosnt sound possible. There are two hundread billion stars in our galaxy, and there are over 100 billion diffrent galaxys. Ill try to find the web page I was on its real cool.
yep, it’s the kind of thing that will drive you crazy 
“The Star Alpha Herculis is twenty five times larger than the circumference described by the earth’s revolution around the sun. This means that twenty five diameters of our solar orbit would have to be placed end to end to equal the diameter of this Star.”
wow, this one is really wow.
That’s just more stuff for our kind to conquer!!! Mwahahaha.
But yes, it is pretty cool how big the cosmic things are. Now imagine how small you are compared to all those.
If you have an awfully large ego, your head will have blown up by now. Good riddance and I hope you burn in the hot place 
.
How could we know that its a fact that the universe is this big? Then again what else would be there certanly not a brick wall. So it would have to be pretty huge, but at the same time it seems impossible. The universe might as big as we could ever reach with a telescope, or sattalite. We could never really know could we. I dont think it is fact, because in ordor for it to be fact you woud have to count every star right? Which reminds me. Has anyone heard an update on the super colider expirament. Did they do it?
Well lets see, first of all the sun’s diameter is only about 100 earths making it’s volume over 1,000 earths.
The thing I find amazing is that statistically, there’s a very large probability that there are other intelligent lifeforms in the universe. Unfortunately there’s a very low probability that we’ll ever get to them or even communicate with them since it would take light over 4 years to get to the next closest solar system. We’ll certainly not be exploring the galaxy any time soon.
Has anyone played Spore? The space age in it really had a large impact on me as to how big our galaxy really is… took me hours to find earth but I did it.
We’ve seen pretty far into the universe and trust me; it’s big
Yes. The universe is big. And if you believe what the scientists say, than it is growing by the second. Expanding and expanding until all the stars and galaxies are so far from each other that if you’d look in the sky at night, you’d see absolutely nothing 
.
Those scientists sure are no optimists are they? Unless you consider their plan to travel to another universe optimism… I doubt there will be many people volunteering to jump in the nearest black hole just because he might end up in a newer universe.
well it’s not just the universe thats amazing, as a biology boff i think that WE are truly amazing. did you know if you took our nerves out of our bodies and stretch them into one big line it would go rouns the sun and back 5 times, and thats true. theres more but i will wait before posting more
If the sun was an orange, the earth would be a grain of sand 11 big footsteps away.
It’s so far away, I can’t imagine it. I mean, the light takes 8 minutes and 20 seconds to reach the earth! And our star isn’t even big.
Universe is fantastic.
I know some of the facts myself.
The biggest thing we can see in the universe is a wall of galaxies, 1,37 billion light years long.That’s a lot.
The biggest diamond found in the universe is 4000km long. That is also the width of Europe.
The furthest quasar we are able to see is called SDSS J11 48+5251(yeah, i know it 
).It is 13 billion light years away from earth.
i can’t remember more facts now…
Looking at something 13 billion light years away, it’s like seeing 13 billion years in the past. If someone was near the quasar looking back, they’d see our solar system before humans existed.
Freaky
It’s kinda like we exist, but in someone else’s reality, we don’t - yet.
So our future is really written in the stars already. -makes you think don’t it.
So if the sunlight takes 8 minutes to reach earth couldnt that allmost mean that we are seeing 8 minutes into the past, because sunlight is allways traveling right?
Yes, but this light is from the surface, the light from the core takes over 1000 years to rech the surface. The reason is that the sun is very compact which makes the light go a few millimeters per second 
I heard an astrophysicist talked about travelling in time. I don’t remember the exact words, but it was something about jumping straight up for … was it 59 years? and back to the eart again, you will land 172 millions of years in the future.
He also said that theres a tiny difference in time between the airplane and us on the ground. Not a big difference, though. But difference, is difference, right?
And the time is different closer to a black hole than farther away. I don’t remember if it goes faster or slower when you get closer to it. But the “biological clock” works fine. A minute will feel like a minute, and not an eternity.
He’s so enthusiastic, that I quite didn’t get what he was saying. Knut Jørgen Ødegård, the astrophysicist, is so awesome.
This is interesting, because sometime in the future, it’s said that anyone can travel to the moon. The astrophysicist said we could do it by 2020, but I don’t know. What if the time is different on the moon? If it’s diffrent in an airplane, it must be a bigger difference on the moon. What if someone travel from the moon to the earth, and end up in the future?
Or am I just being silly now
who knows??? it could be possible 
Why would time be different on the moon? There is a difference in sensing time on a plane because it moves very fast. When on a rocket and flying to the moon, that could make a difference. But just standing on the moon? No, I don’t think so.
Besides, time may not exist after all.
From what I understand, the difference in time you were probably talking about comes from Einsteins theory of relativity which states that the speed of light in a vacuum is the same for all observers.
Now think about that, if you have one person traveling half the speed of light in a spaceship and he flies past another person standing still, both of them would see a beam of light travel at the same speed (relative to each of them). This goes against most people’s intuition. The funny part about this is that the components of speed, ie time and distance, are not constant. To the person going half the speed of light, time moves slower so light traveling a farther distance will result in the constant speed of light. And vice versa for the person standing (relatively) still.
It can be a difficult idea to wrap your mind around and I hope I explained it well; I’m not a physicist. As I understand it all normalizes when you accelerate or decelerate.
ps the moon is moving relative to us
I heard time doesn’t exist in the black hole.
If you were pulled into a black hole (and somehow kept yourself from being ripped apart), you wouldn’t notice any difference in time. However, you would be traveling very very fast. If you could compare with a clock far away from the black hole, you would notice that clock speeding up (or you slowing down(time wise)). Once you slow down(speed wise) (or come to a screeching, bone-crunching halt at the point of the singularity) your time-frame would normalize and the clock far away from you would appear to show correct time.
At least, that’s my theory.
If its true that all the matter compared to space would be a grain of sand in a 20mile square room how is it even possible that we would see any starts? I mean once that grain of sand has been split up… I mean danm. And too think a star is the 25 times bigger then the circonfrence of the rotation around the sun. Holy shit!! I am so fassinated with this stuff. I love it. I mean we are are nothing compared to the universe.
