Wait... 15 things we didn`t know? Isn`t it a bit odd to assume we don`t know the Sun is the biggest object in the Solar System? I mean, an elephant might be bigger than the moon, but certainly not the sun.

Everyone knows the sun is the largest object in our solar system, that Jupiter is the largest planet, that screams cannot be heard, and that liquids form spheres. For freaking serious.

that whole seen from space thing really depends on your definition of space, low orbit like the kind a jet can reach or waaaay up there.

I would think that every one would know number 1

Oh, piss off. Sounds like a waste of time to me.

Go back a while and you`ll notice that

A) I`ve been pointing out Siyanor`s stupidity since... Well, a pretty damn long time.

B) He`s wrong, plain and simple, and yet he NEVER F*CKING ADMITS IT. He gets pissy and puts on his superiority complex hat and acts like he and the people who agree with him are the only cultured, intelligent individuals on the planet.

So yeah, f*ck off captain White Knight... You don`t know the history of the princess you`re trying to protect...

[quote]none of this information is on a national standard for schools.[/quote]
Dude, you`re wrong right off the bat. I knew #`s 2, 4, 5, 6, and 9 before 5th grade from science classes.

It might not have been standard in your little "short bus" class, but still...

Also while I was in elementary school, my 5th grade science teacher taught us about black holes. So, I guess it`s NOT so obvious that nothing would be taught about them in schools. In fact, it`s not even true. So, with that...

[quote]Rick, according to your inability to read both my post and your own link, I`d say I needn`t comment further.[/quote]
Is it so physically impossible for you to get over your petty ego, shut the f*ck up, and accept that you`re wrong for once?

I would call you a troll, but I get the feeling you genuinely believe the bullsh*t you spew...

>>humans radiate ~2000 calories/day, I`d say that`s quite a bit

>>LOL! Fat people LOVE TO TELL THEMSELVES LIES!

I can`t say I`ve heard of this statistic, but
2000 calories = 2 (food) Calories = about one Tic-Tac

That`s not a lot.

many of those are well known facts. It should more accurately be names, 7 facts you more than likely don`t know about space and a few you more than likely do.

And, in addition, there has been a recent discovery which changed the number of galaxies from est. 125 billion to an est. 500 billion galaxies. I`d say this poster is a bit old.

Do you really eat two MILLION calories a day, Angilion? That`s amazing!" I believe Angilion was referring to calories, Which happens to be 1000:1 of what we NOW call Calories with a Capital C (or KiloCalories), So in response to your question, Yes, he does in fact eat 2,000,000 calories everyday.

@BigMordecai - The poster is a bit misleading - it means lightest as in the least dense, meaning it `could` float on water, while none of the other planets could.

@Angilion You actually beyond saving a minute thirty seconds in after which your blood begins to boil. Nothing interesting here but in reality Saturn is not the lightest planet. Last time I checked it had the mass of about 95 earths.

[quote]humans radiate ~2000 calories/day, I`d say that`s quite a bit[/quote]

Not in comparison with the ~2,000,000 calories/day that humans eat. A human who was alive would easily generate more than enough heat internally to compensate for radiant heat loss.

[quote]not really, waves from the sun radiate with enough strength to burn you way way out of the solar system according to data in voyager II[/quote]

Yes really - you would not burn to death unless you were very close to a star. You`re going to be dead in a minute - you`re not going to burn to death way way outside a solar system in less than a minute.

deeplick, none of this information is on a national standard for schools. Most schools don`t teach any of it.

Also, if you`re truly 18-29, the vast, vast majority of people didn`t believe in black holes when you were in elementary school. Obviously nothing about them would be taught.

But we have to lose it into the air, onto other surfaces. In other words, conduction, not radiation.

Radiation is giving off pure energy, which means no other molecules necessary. Like light. Light is a form of radiation.

The heat people normally give off is carried through perspiration and contact with air, etc.

Funny enough, we apparently DO have some natural bio-luminescence (which would be radiating energy)... A scientific study showed... Wish I could find a link.

[i]My understanding is that it is impossible. You can chill something down to a tiny amount above absolute zero, but never quite to absolute zero. [/i]

theoretically it is possible for small amounts of time

[quote]What I am intruigued by is the fact that you would get burns before you would freeze to death...[/quote]

If I`m right in my understanding, you would never freeze to death in deep space because you could easily generate more heat internally than you would lose. This is assuming you could somehow survive, which of course you couldn`t. You wouldn`t even live long enough to die from lack of oxygen and you`d have to be very close to a star to burn to death. Lack of pressure would almost certainly kill you first.

You lose heat very slowly because there`s almost nothing to lose it to. If you pretty much rule out conduction and convection, only radiation is left and humans don`t radiate much heat.

A couple of billionths of a degree was probably considered close enough for a casual infographic on the net.

More like 15 things I did know about space. Though the one about metal adhering instantly is untrue. It takes some time to adhere, though not a whole lot of time. NASA typically coats the metal objects they send up just as a precaution, but it is unlikely that a situation will arise where metal might adhere, even if they didn`t.

Saturn wouldn`t actually float in water, even though mathematically it`s less dense than water. The icy rocky centre would sink in water and the gases would float away.

That`s because you`ve misquoted the article. The Sun has 98% of the MASS of the solar system. Hence the solar system revolving around the Sun.

And this should really be called "15 things you most likely already know about the solar system".

@ardystic considering the volume of the sun is 1.412×1018 km3 and the volume of saturn is only 1.43128×1015 km³ then it sounds right. After all the sun is therefore 1000 times bigger than the next largest object.

If every 100 years, the earth slows down 2mm, I seriously doubt that after 100 years from today, the day will slows down by 2ms.

The proportion is not right. But I`m too lazy to go to the source and check. Baw, i-am-bored
