That's pretty common knowledge man. In fact it's not even close...the number of stars in the observable universe well exceeds grains of sand on earth. And since our star alone has 8 planets, which in turn have up to 30 moons (jupiter) you can start to appreciate why that one guy posted that extraterrestrial life is a mathematical certainty.

Correction: jupiter has 63 moons.

has the common knowledge counted them?

have they named them?

Your hands are actually being repulsed away from one another. If you hands were to actually touch (not be repulsed), you would have a big problem on your hands (pun intended).

Interesting. I was not aware of this. I understand electrons, neutrons, and atoms.
And I guess if I had thought about it more, I would have realized that this was a given.

Thanks pkt

Actually the latest calculations from the rate that they are discovering planets suggests that there are more planets than grains of sand on all the the beaches on the planet EARTH.

I feel like in order to be able to make that kind of assumption you would have to be able to somehow get a count of the number of grains of sand on the earth. Which would be all but impossible.

No, you can come close enough with an estimation. It's also impossible to count the number of stars in the universe because every second new stars are created and old stars die. The speed of light is a constant, so we're seeing stars now that could potentially have died millions of years ago and we won't see the new stars for millions of years. Read the link that I posted, it outlines perfectly how that estimation was done and you'll see that there's a massive gap between the number of grains of sand and the number of stars in the universe. It's a short and sweet read.

You can't put exact numbers on such large quantities, but you can calculate what's called a "margin of error". In this case, the margin of error for stars in observable universe well covers for any discrepancies in numbdr of sand particles on earth.

I almost get the sense that those guys don't want this to be true or something. I mean, it is a little intimidating I guess, but in a good way.

People say that the universe it too big for human brains to comprehend, but it'll never happen with that kind of attitude.

The universe is and will always be too big for that human brain to comprehend. The human brain cannot comprehend infinite, and one must assume the universe goes on for an infinite measure of distance. Even if the "universe" itself does have some form of barrier that marks it's end, how deep or wide is the barrier?

The human mind is designed to think from beginning to end. There must be a start, and there must be a finish. But again, that's negated by the fact that you must assume the size of the universe is infinite.

I say the human mind is "designed" that way, and yes I mean designed. I will leave it at that but we are a fraction of someone who always was, and always will be. There was no beginning to his existence and will be no end to his existence, and we cannot comprehend that.

But I'll stop there so we don't get too much into the "God crap" that you hate so much.

Instead of trying to debate philosophy why don't you acknowledge my original retort, or Insuneri's. It's a mathematical FACT that there are more stars than sand.

I don't "hate" God crap, it's just annoying and doesn't belong in a science thread. It's philosophical at best.

Fractal Mathematics for the coast lines and from there just the number of gains in a cubic foot of all the different kinds of sand then laser satellite imagery for depth and so on. They can calculate closer the grains of sand than the number of stars....just a guess but seems logical.
