For a long time, people thought that Astronomy was basically 'dead.' The stars and galaxies had been discovered, we had been to the Moon and it was pretty boring, we had robots cruising around Mars, and after the excitement wore off, it was pretty boring too.
But a few things happened that told us that Astronomy was making great breakthroughs. We saw things that changed our ideas of reality.
One biggie is the Hubble Space Telescope. One day, they decided to look at a little black piece of sky that was, well, empty. When we had looked there from Earth based scopes, in was just - empty.
So, the HST (Hubble Space Telescope) took a long long look at that little empty place in the sky. A 1 million seconds long exposure to see if it could detect something - anything.
It found in that little spot of sky, about 1/10th the diameter of the Moon, thousands of galaxies! Look at the link. When this number of galaxies is multiplied by the area of the sky I estimated that - in the whole sky - in the BLACK part between the stars we can see form Earth - that there are 2.83824E+17 galaxies that could be seen from Earth, if we spent the time (1 million years) to photograph all of the sky.
;-D That is: 283,824,000,000,000,000 galaxies! In the dark sky beyond what we can see from Earth!
For the last 40 years, Astronomers and Solar Physicists have been studying the Sun. They are putting together a theory about how the Solar System was formed that is far different than what I was taught in school. It will cause an uproar in the science community as more and more people hear of it, and can not accept it: The Sun is what is left of a Super Nova that occurred 5 billion years ago.
Most astronomers will doubt it. It seems like a good theory to me. Some call it bunk or rubbish. But it is not a 'off the top of the head' theory. The latest data has been used to formulate the theory. I hope you read all about it when the argument starts!
;-D I just want them to invent anti gravity so I can float to where I want to go! ha ha!

This is not a matter of point of view. The religious idea of an everlasting immutable universe is simply not true. it's dynamic ever changing and as to the infinity of it...well...it depends on the definition of infinity. Again the religious concept is not true. The scientific one depended on whether the universe will keep on expanding or will gravity finally prevail and the whole thing would collapse again in to a singularity in a big crunch and then bang again. The expanding one will, at some given time trillions of years from now , freeze to 0 degrees absolute. The end of all motion. the ultimate death. In both scientific views time is does not exist alone it's part of the time-space continuum. One does not exist without the other. So no infinity.

At the moment, science can prove only very much limited stuff. Like the great Newton said, we are only children licking pebbles on the shore while the ocean of Knowledge is in front of us. Time will solve a lot of questions for us - bit for the moment, I personally don't think that the universe is for ever and ever, there definitely is an end, where I do believe starts another universe and there are millions of other universes etc. Black holes for me are gravity holes that pulls everything around it. These are scientific views that I believe in.

I don't think our universe in infinite.
I do think that from our point of view it will always look that way though. There is a limit to the amount of our universe we will ever actually be able to see The "horizon" for what we can see is so far away that it will not change to us even in the life cycle of our sun. Depending on what data you are using there are estimates that our Universe is between 46 and 76 Billion light years in radius. They estimate the Universe to be 13 plus billion years old and our solar system to be less than 5 billion years old. The outer edge, if there is one would then be at least 25 or 30 Billion light years from us and traveling away.
Maybe the whole universe has already used itself up and we just aren't going to know about it for a few billion years.

I think that the Universe is either infinate or wraps around. It makes no sense to me that it would have a definite border. That sounds so 'flat earth' to me. I also think that physics might be different in different parts of the Universe, and this is not an accepted view. Black holes? They are so massive that not even light escapes from them, right? Maybe they account for the calculated Dark Matter that the Universe is supposed to have but we haven't yet found. The black hole may be a 'hole in reality'. If this is so, then there may be layers to reality and the physical is but one part of existance. That Dark Matter that they can't find may exist slightly beneath the 'surface' of physical reality, just enough to influence it, but not 'there' enough for us to see at this point.

This is a bit of a tangent, but using words such as "infinity" is a bit delusional. It gives the feeling that we have a real grasp on the subject when the subject is beyond any grasping and any definition.
Another such term is nothingness. It's completely unpicturable, because it implies the complete absence of pictures (and everything else.) But we can throw the term around as if we've got a good picture of what it means.
Such terms still come in handy as a practical matter. And their relevance reflects the inherit illogic of there being a universe at all.
Ok. That's all for now.

I think allot of things are happening in the world and universe but NASA all-ways hides reality of theories and same like about UFO,s about AREA 51 etc ,all scientific concepts are based on old research and coz of NASA and MIR monopoly all concepts are still same like be for 50 years so how we can accept about universe still we are not confirmed how much Planets in our Solar system , and we know about Black Holes but now also we have new concept of White Holes there we see stars are come out .

I accept that the universe could be infinitely big...but I believe the way that we define that infinity will change with time...We aren't at the stage where we can really make educated guesses like that, same with black holes, the theories they have now will almost certainly be challenged and probably some of it will be proven wrong...

It's true. Believe me - man is understanding the nature and intepreting. He may not be right all the time but true in fundas.

i maybe smart, i like to listen to these scientists arguing about the this and that of the universe, but sometimes, its far easier to believe in religion.
