Physics, Astronomy & Cosmology / What existed before the Big Bang?

« on: 03/05/2009 20:26:16 »

The concept of 'before' implies TIME. If you are considering a region (not a time) in which the idea of time does not apply, then you can't use time - based words, such as 'before', with which to discuss it.

So if we cant used time based words to speak theoreticly about "the big bang" what words can we use?
What if there was something there before the big bang, would we then change when time started?
Were saying that before the big bang there was nothing but it is only a theory, im sure everyone here has a theory of how the universe came into existance, but i don't think that there was ever nothingness. Is infinity not a posiblity to anyone? can nothing last forever? what about us, i know our bodys decay when we die but then the soil absorbs us, we become pasrt of many things, they die and make many more, maybe something like that hapens with universes... maybe not, only my view on the matter

Also you could try using Mozilla Firefox, its a much better web browser than most see details and download at http://www.mozilla-europe.org/en/firefox/

Plant Sciences, Zoology & Evolution / DO COWS SIT DOWN WHEN IT IS GOING TO RAIN

« on: 02/05/2009 23:47:58 »

It hasn't been proven (to my knowlege) but cows could due to sencing a change in air pressure that we dont therefor knowing its going to rain and posibly keeping a patch dry, just a theory.

Chemistry / What is the difference between a non-Newtonian liquid and a gel?

« on: 02/05/2009 23:40:33 »

Gels are mostly liquid, but they behave like solids due to a three-dimensional crosslinked network within the liquid. It is the crosslinks within the fluid that give a gel its structure (hardness) and contribute to stickiness (tack).

A non-Newtonian fluid is a fluid whose flow properties are not described by a single constant value of viscosity.

So in conclusion; Some gels are non-Newtonian liquids but some arn't and some non-Newtonian liquids are gels but not all.

General Science / Why don't satellites gravitate towards the Earth but stay in orbit?

« on: 02/05/2009 23:23:20 »

Well this is indeed the result of tidal forces. The gravitational force of the Moon "pulls" on Earth's oceans and crust, creating the tides. Earth's gravity also pulls on the Moon, distorting it so that it is slightly egg-shaped. These tidal effects produce bulges on the Moon's surface, and Earth pulls on these bulges a little more than on the surrounding regions because of the concentration of mass there. Earth's constant pull on the Moon's tidal bulge caused its rotation to slow down from its much faster initial spin rate to its current rate of 27.3 days.

Physiology & Medicine / What Is The Liquid In My Blister and Other Blister Type Questions ?

I know its been a while since this was last active but the stuff in blisters is either lymph its the stuff your blood cells float around in or serum which (in this case) is blood plasma with the clotting factors removed
