pressured

someone tell me again why I keep deciding to take things upon myself?


Typing this early in the morning is so not me. But since I'm no longer sleepy ('coS I've gone into an awake but zombie-like state, and also on the verge of insanity) so I'll type a bit.

I've been kept up by all the researching data for an exhibition. Apparently I'm not used to this kind of stuff, too much information flowing in every direction. I hope the exhibition goes well, this much effort has been put in. On a brighter note, I've learnt how to use OpenOffice slightly better.

I may fall ill soon, there's a virus in the house. I'll try to ward off the symptoms, but there's no telling if it will gain a foothold in me.


Now for some basic physics which show why stars can't form on their own. Take the equation PV=NkT. Rearranging, we'll see that pressure is proportional to the product of temperature and density. For a bunch of gases in a nebula to start thermodynamic fusion, a high pressure must be developed. Now an increase in pressure would correlate to an increase in temperature and density. But we're talking about gases in space here! Gases in space naturally expand 'infinitely', ie, gases take up the volume of their containing space. Hence the gases of a nebula would rather undergo expansion than gathering together, in the process experiencing volume cooling. Thus stars can never form from gases collapsing into a point - gases would rather move the other way. Without an external force pulling the gases together stars won't come into existence.
