Ok since u guys are really smart i want to know........

Is the Universe Exanding?

and if its true then how did they find that out?

And who found it out?

Oh and another question is.........

Why do fools fall in love??

[quote:post_uid0="princevegetam"]wrong SBYRD, now let me explain how a star is born and dies

there's two types of stars, one is the type our sun is and the other is damn, i forgot its name, lol.

anyways,

Process of a star like our sun:

nebula: infant stage of star, when it's still giant clouds of hydrogen

next, it starts to become very dense and heat up, and eventually, nuclear fusion occurs in which hydrogen atoms are fused into helium

after all these other stages of the star(i won't go into specifics, since i don't have much time)

it becomes red giant, like you described SBYRD

then it becomes a helphoid(can't remember what it's called) where there is very little hydrogen left and most of the star is helium, and the helium starts to fuse with itself into carbon.

and then finally it becomes neutron star(a.k.a white dwarf) with extreme gravity because the red giant's core collapses on itself

The other type of star's process:

the star pretty much follows the same process, except it becomes a supernova instead of a red giant. the supernova goes through the same thing, except it has a possibility to become a black hole or a pulsar.

anyways, a blackhole's tremendous gravity CAN infact cause a nearby star to go nova.[/quote]
Prince is correct I wasn't complete in my thoughts on that.

Tupac I think the Universe is still expanding because of the heat that is still given off from the Explosion that made the Universe.This theory is called "The Big Bang Theory".It basicly states that the universe was perhaps very compressed at one time.The pressure made a massive explosion that thus created the planets and etc.

Now, some of you are wondering how did life begin on earth.Ok, I'm going to give the scientific answer even though I'm a christian.There was a lake on earth after the molten rock cooled to from natural rock.My guess is that the lake was made by the ice in space.

Well, anyway in that lake,pond,etc.There was bacteria the first form of life.This bacteria evolved and so on.

Fools fall in love(That is not a science based question)

Because there names say it all,but a real answer is that there attraction for who ever grows so strong that there willing to make hardships for them self to see the other recieve affection or joy.

okay, here is a question for all you "scientists"

tell me how you would define a living being.

what facts would you base on to determine whether a "thing" is living or not?

(don't give me retarded answers like: well, use your common sense!)

if it breaths, eats, move around, sleep and is composed of cells, not molecules, its a living thing.

cell: the smallest unit of living things. e.g.: skin cells, muscle cells, white blood cells.
molecule: a non-living substance. e.g.: oxygen, carbon, hydrogen.

molecules are also in the periodic table of elements. there are currently 118 elements. who can name them all?

uh... actually i think almost all living beings are made out of molecules.

cells: what is it made out of? molecules of carbon and other stuff

molecules: not elements, but multiple elements combined together

e.g. water has molecules, oxygen doesn't have molecules, it has atoms

yall kinda smart damn didn't see that one coming
:0

Actually, my theory on Smallest living thing is diffrent.

*Booting up First year Chem. Honors student*


Well, Snake is right, Cells are the smallest unit of life, but my theory is, what are the cells made of?

Basically, in the human body we are mostly made up of Water. Which is what children? H20


*points at Electron Dot Diagram*

So you see, Living things are made up of basically O2 and H, otherwise why would we always have to have something to drink after running a marathon or something simliar to that effect

*and meh, I forgot what I was going to say with the electron dot diagram.*-_-

molecules are elements. go look it up.

O is a ELEMENT

A Molecule is a bond of a Element to another Element

Atoms are Nu-, Pro-, and Elec- trons

[edit] and Snake had to edit his post. :biggrin: well, I'll leave it up for others. [/edit]

your all WRONG.

a molecule is made up of three subtances:

protron
neutron
electron

now hydrogen is made up of one protron, one neutron and one electron.
oxygen has eight.

now put two oxygen molecules and one hydrogen molecule together and you got a compound. a compound is two or more elements mixed or fused together. and a element is a molecule.
