<br />why does this not strike you as a finite situation?,when the planet does die, no matter the reason it will, it will take all the universe with it.<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">All the <i>visible</i> universe, yes, of course. Did you think everything we see was going to last forever? All forms are finite.
<blockquote id="quote"><font size="2" face="Verdana, Arial, Helvetica" id="quote">quote:<hr height="1" noshade id="quote">now since it is just a matter of scale, physics is the same, how does something 1000 times the universe's size produce something billions of times smaller than even an atom?<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">The megaplanet (remember, this is an example of what might be on a larger scale, not a definite thing) might have a mega-atmosphere whose molecules are our galaxy clusters, and whose atoms are our galaxies. Or the elysium filling our visible universe might be like an ocean of the megaplanet, with galaxy clusters playing the role of water molecules instead of air molecules.
Either way, all mediums remain infinitely divisible. Just as Earth's oceans are filled with water, which is made of baryons, which are immersed in elysium, which is continually bombarded by gravitons, the same is true of larger-scale media too. Every medium on every scale is part of an infinite continuum of mediums both larger and smaller than itself.

Our universe is already filled with elysium, the light-carrying medium. Its total energy content defines "absolute zero" on our temperature scale, which might turn out to be relatively hot compared to the energy available in "vacuums" elsewhere in the larger universe.

But you are taking these terms too literally. The basic rule of thumb is that all scales are fundamentally the same. There is no observation you could make that would tell you what scale you are on. It's all relative, in a sense much deeper than Einstein ever dreamed. -|Tom|-
