You're only referring to animals. There are many plants - trees, specifically - that have been alive for much longer than 175 years.

Somebody else would have, and Columbus, OH and Columbia, SC would have different names.

Big deal.

or if the Pope had killed Galileo and his belief that EARTH wasn't the actual center of the universe
Galileo recanted, so the Pope got his wish.

Big deal.

Einstein came along later and demonstrated that the universe does revolve around the earth, if that's how you want to view it. All motion is relative.

what's gonna happen if we develop telescopes that see beyond our solar sytem and we find something MORE?
My telescope can see millions of things beyond the solar system. They're called deep sky objects.

here is one: there are currently more people living on the planet right now than have ever lived on the planet before. meaning: take all of the worlds populations form the dawn of time and add them all together and there are more people alive right now than that number.
this is not true.

I do not believe that is true. While population growh is expanding exponentially, all you need to do is look at the graph of human population growth from roughly the 1200's and you can see that if you add up the area under the graph it's much, much larger than the current population figure. This makes complete sense because any two previous human "generations" should be more than the current one, muchless all those before it.

I do have little doubt that there are more people on earth at this given time than every before, but not combined.

It will be interesting to see if that trend continues by the time we expire.

Wow. Someone was on a bender last nigh, eh?

Jupiter wind speeds -
232 mph at cloud tops
293 mph seven miles down
313 mph 10 miles down
360 mph 17 miles down
391 mph 28 miles down
390 mph to the end of measurement by the probe at 60 miles down

That's just normal for the planet, not specific to the great red spot.

Pressure went from 0.5 bar to 21 bar. (Over 300 psi.) Temperature ranged from -230 F to +306 F.

Jupiter doesn't really have a surface, by the way. While it at least 4% of it is made of stuff more dense than the gasses we see, it's at such great pressure and temperatures (20,000 to 30,000 kelvin, estimated) that its like the planet just gets denser and denser the further in you go, eventually turning into a big mass of molten gunk. No idea if there's a gradual change, or if there's a clear boundry between one layer and the next. The pressure down in the core could be as high as 650,000,000 PSI, by the way.

From wikipedia:

According to one set of calculations based on 2002 data:[23]

The number who have ever been born is around 106,000,000,000
The world population in mid-2002 was approximately 6,215,000,000
The percentage of those ever born who were living in 2002 was approximately 5.8%
The claim often made in various popular sources that more than half the humans ever born are alive today, is therefore in all probability quite exaggerated.
