Big question? You need kurzgesagt
the speaker asked us to visualize a billion, a billion anything, a billion pinto beans, housing units angel dancing on the nose of black-backed Jackal?
I can visual 10 and 10 fingers and toes, 6 guitar strings, 88 piano keys, a partridge in a pear tree
1 year with out looking at a calendar? nope, 70,000 cheering fans at a Jets football game ugh-uh no way that's never gonna happen, driving from Fresno Ca. to Akron Ohio 768,433 times, nope
The other end?
You can't get there from heah...
The edge of the Universe is not 'out there'.
But, it is a common misconception, I understand your dilemma.
There's about 10g of 'air' inside a football. And one mole of hydrogen has a mass of 2g. That means it takes about 5 moles, or .005 kmol, to fill a football.
That means that we would have to throw a football across 30,109,598,940 universes to fill a football with the hydrogen necessary to fill it, give or take.
Well, to get to the edge of the universe from here, you'd have to go through Oildale. If you decide to take that trip, I'd advise you to pass through there while it's still daylight.
If that's what it takes for Tom Brady to be happy with his the inflation pressure of his footballs, then it will happen.
Well, it might as well be Northern VA/DC because I sure as hell ain’t driving there anymore if I can help it.
The smallest and farthest zeppelin.
multiverse, yes - many worlds interpretation, no
our perfectly-tuned-for-life universe that is poised like a pencil balanced on it's point, seems to lend itself to the reasoning that because of the many things that come together for life to have happened, the other infinite number of universes that DO NOT have life must be there - pretty frickin' strange.
the dark energy is also expanding the size of our universe
light has a speed limit , space itself does what it wants - as fast as it wants - for as long as it wants, without limit. cool.
what a time to live in - where we know this...!
Pretty far out man!!!
"mathematics tells us they're there..."
And we were sure there was "the ether" until a new paradigm of understanding rendered it unnecessary and obsolete. @Obsessed had it right. We need to grow up before we can grab the brass ring. Breakthroughs in physics come in big, bold, upsetting revolutions as we continue to grasp how the limitations of our thinking drawn from our senses and daily lives have led us astray.
A 10K run under 30" and you're there!!
There is another view of the edge of the universe. Some physicists see reality as a hologram on the edge of the universe. That either means that the edge has thickness or our Euclidean understanding of the three spatial dimensions in our daily experience is incomplete. And space-time is warped by gravity. No single concept is too difficult to visualize by itself. A synthesis where all are valid stretches my mind to the breaking point. And who said physics isn't fun.
And don't stare into the sun looking for answers.
