Perhaps now. But you're looking at a moment in time. Who's to say that one day we (or earth based life anyway) will not be as far advanced from us as we are from say an earthworm. Or even an amoeba.

What's wild and scary is that the universe is expanding at an alarmingly accelerating rate...and we don't know why.
Clearly, the answer is climate change...

So how did space itself come into existence?

Cosmologists still claim the only remaining hypothesis is the Big Bang.

^^That's great and all, but what is the black stuff around the universe? That has always been the stumper to me.

Animation of two galaxies colliding

IMO it's just space not yet inhabited by matter. But with an ever expanding universe (though slowing, still expanding), it may be inhabited at some point.

Not slowing, accelerating. There's redshift in all directions.

I wonder how many years are compressed into that 2 second animation?

I think that's the stumper for everyone.
If the universe is so big, what was there before the big bang. Nothing? what is nothing? makes my brain hurt.
would you give up your life on earth this second, if by doing so you would know every answer you could possible ask about the universe, and even the ones you wouldn't even know to ask? This assuming if you don't choose this you live out your life and die and know nothing.

I don't think humans can survive long to get to that point but even so, even that kind of growth is still simplistic and miniscule compared to the size and complexity of the universe. And when I say universe I mean whatever started it, is outside the barriers of it, multiple/parallel universes, etc. I just highly doubt a human brain, the organ itself, can figure out what the hell is going on.

"Belief" has always been one of the biggest problems facing science. You have no basis for thinking something, but you think it anyway, call it "belief" and hold it out there as something that is perfectly reasonable when it is, in fact, the opposite.

No, it's estimated there are at least a billion times more grains of sand on Earth than stars in the Milky Way. What you're saying is thought to be true for stars in the Universe.

and there are more galaxies than the stars in the Milky Way.
That appears to be the current thinking, perhaps by a factor of 10.

I found an article that talked about grains of sand in the sextillions, which is 10^21. Combining with your article, 10 million to over a billion times as many grains of sand on Earth as stars in the Milky Way. What's a factor of 100 anyway?

I knew what he meant, just making a correction....all are staggering numbers.
