Anyone interested in this topic? or matters concerning the universe? I find it endlessly interesting to think about gravity and the Big Bang, expansion of the universe, all those things related to astronomy. (not astrology)

I like finding out why the earth has an atmosphere and the moon and many planets do not. (molten iron core sets up magnetic force-field that shields solar wind which would strip atmosphere if mag field not present.) Stuff like this.

Black holes and worm holes. Theories of space texture and shape. All this stuff tends to make you feel completely insignificant. For some reason this appeals to me.

Einstein and his thoughts, parallel universes, time-space continuum. Time travel. Endless possibilities of other earth-like planets, even a Pandora.

I never liked TV Star Trek or Star Wars but I like the subject of astronomy.

I like it all. Where do you want to start this here conversation?
Gravity. It's not yet understood fully. Some attribute it to the "weight" of space fabric pressing objects to larger objects and others like to think larger bodies (planets) have an almost magnetic property all their own and pull other things in.

The biggest problem I have discussing these topics is a lack of proper vocabulary or jargon as related to this subject. I can see things related to planets and space in my mind's eye but can not easily articulate them. I'm sure you can relate. This subject is best discussed with a chalk board handy to draw pictures and diagrams.

Although one of the four forces that unify nature to our current understanding gravity could be an expression of the three other forces and the interaction on mass, and the matter that is there in contained.
If you really want to go into it ,Gravity has a minimal effect on the micro yet a significant effect on the macro. It leads back to the theory of gravity as opposed to a law because the three other forces have a definite effect on mass regardless of it's size.
It could be that gravity is only an explanation for planetary physics and not the explanation of the actions of the universe as a whole.

Okay, it looks like you could beat the crap out of me in a gravity fight. I'm a bit lost. Sorry to lead you into thinking I actually know something about this subject. How about the moon? I say it's not green cheese. (don't hurt me)

fun, dark energy. The expansion of space and the need for energy to do so. Where does this energy come from? It did not all come from the Big Bang because the expansion is speeding up. Once a body is set in motion, like a bullet, it can not gain speed on its own. If you expand air on earth, you cool it. This is the opposite of dark energy. Energy is motion or heat. Yet space expands and needs energy to do so. Where does it come from and how is it manifest? This is beyond me.

You me and most everyone else. This is the point of the Hadron Collider . The issue is whether or not the materials were present before the big bang. The Big bang isn't the beginning. The expansion of space isn't based on energy. Think of it like butter on toast energy being the butter and the toast being invisible. The further we can spread the butter the more toast we know is there, but that doesn't mean the toast was never there. It just means we couldn't see it.

funetical, the thing I like most about thinking about the cosmos and all the distances involved, all the unanswered questions, is the way it makes me (and all my earthly issues) feel completely insignificant. I'm not a religious person at all. Can't say I really believe in a supreme being, but I sure can understand how a person could after contemplating the universe and all that is in it. All that we can imagine is in it. There must be so much beyond our scope to comprehend.

Our comprehension of the universe is only relevant to our place in it. Which unfortunately right now is small. The farther we progress in space the more questions we will have but also more will be answered.I feel connected to everything and that makes me wonder.
Curiosity is what gives me hope for mankind.

For the longest time now I've wanted to buy a quality telescope. Someday!
I have a brass naval model that was given to me. I have never pointed it above the apartment building's roof opposite where I live. (The place is crawling with young women.) Night time is the best for observing celestial bodies of all kinds.
