Outer Space....and....who are you...

I'll never forget me dad talking about mind boggling / blowing things and one that sticks in my mind to this day was....where does space end, is there a brick wall, but what's on the other side ?

If you actually think deeply enough about it your brain simply can't take it in, well mine can't anyhow and I get a little dizzy or light headed trying to imagine it.

Anyone got any suggestions where space does end?... no daft answers please, any pratt can do that.

It does seem too much to comprehend, what is out there beyond what us little earthlings can see.

 

We think we have a bit of understanding about the vast "universe" that surrounds us, but does it go on forever without end?

 

If there is an end to it all, what's after it?

 

Are we part of a vast plan run by an all-powerful creator?

It really is too much for our minds to comprehend isn't it !

 

It's like going into your own mind and trying to think who the hell or what the hell you actually are, seriously strange feeling!

Space is big. You just won't believe how vastly, hugely, mind- bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.

Douglas Adams, The Hitchhiker's Guide to the Galaxy

or

The contemplation of celestial things will make a man both speak and think more sublimely and magnificently when he descends to human affairs.

Marcus Tullius Cicero, c. 30 BCE

Quotes aside, here's an idea that will really bake your noodle:

If our universe is about 13.7 billion years old, then the most distant celestial objects we can possibly see are those whose light has traveled 13.7 billion years to reach Earth. However, because the universe is expanding, those celestial objects are actually over 13.7 billion light years away as we speak.

Furthermore, we can only see the part of the universe that's centered around our Earth in a gigantic imaginary sphere, with light coming in from every direction. Put another way, the part of the universe we can see is solely within our cosmic light horizon. We can't see anything past this horizon because light has not reached Earth from beyond the cosmic light horizon, since the time required for this would be greater than the present age of the universe. With time, more light from more remote places will reach Earth, and the size of our observable universe will increase. All of that helps to partially explain the darkness of our night sky.

Spacetime is weird. Strictly speaking, if you put the observable expansion of the universe into reverse and start winding the clock back, you get back to a point known as the singularity and if Einstein was right, there is no "when" before that and more weirdly, there is no "where" outside of it for it to expand into.

This is all well and good as an expression of relativistic physics, but it does start to sound like the old theist argument that their god was always there.

“The Cosmos is all that is or was or ever will be. Our feeblest contemplations of the Cosmos stir us -- there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, of falling from a height. We know we are approaching the greatest of mysteries.”

You can't get anywhere near theism from mathematics though.

The problem isn't what people don't know, it's what they know that just ain't so.

He obviously didnt get out much

Believe NOTHING anyones says or writes unless you witness it yourself and even then your eyes can deceive you

None of this "the enemy of my enemy is my friend" crap it just means i have at least two enemies!

 

There is only one opinion i listen to ,its mine and its ALWAYS right even when its wrong

 

Its far easier to curse the darkness than light one candle

The universe is (as far as we can work out) a 4-dimensional toroid (think doughnut* with extra timey-wimey stuff). The observable universe (the bit we can see) is a 3-dimensional circle on the surface of the 4-dimensional doughnut. How big the observable universe is in relation to the whole universe is a moot point, it could be a couple of % or it could be as much as 10%, some say more than that.

 

What happened before the Big Bang? That is something we will probably never know, simply because our physics came into being at the moment of the BB itself. What we do know is that at the moment of the BB, for every 1,000,000,000 atoms of anti-matter, there was 1,000,000,001 atoms of matter. Since matter and anti-matter don't get on very well together, the birth of the universe was (if you could hear it) very noisy as the matter/anti-matter annihilated each other. Our universe is made up of the extra 1 atom of matter per billion.

 

What boggles my mind is that the iron in your body, gate, manacles or anything else once led to the death of a star.
