Let me help you understand the question first. On another thread I posted: -Everything - as in everything - is measured in quantum units ⇒ summations of quantum units cannot = f∞. Period! Summation: The universe cannot be infinite in size, mass or age. But isn't that a tautology? You are saying som...

Why should the universe have an origin or beginning? Seems to me this assumptions needs to be examined before you can start entertaining specific scenarios, espeically since it arguably makes a nonsense of the word itself. How can something universal have an origin? For thousands of years before mod...

[quote="BMAONE23"]13.7 Billion LY is only the distance that we can currently see from our point in space, but we can see 13.7 billion LY in any/every given direction. This creates a sphere of 27.4 billion LY of which we reside in the center. We cannot be in the exact center of the universe...

[quote="Qev"]Actually, floating ice, when it melts, really should raise the sea level, albeit only slightly compared to non-floating ice melt. Sea water is more dense than fresh water, and ice is (primarily) composed of fresh water. As it melts, it dilutes the sea water, lowering its densi...

Interesting that we tend to say that such a galaxy *is* "about 170,000 light-years across." In reality it *was* that size 25,000,000 years when the light we're looking at was generated. Who knows what it's like today. So the "observable" part of the definition of size tells you h...

[quote="fastartceetoo"]This stuff belongs on some mystic page, not APOD! It goes right along with such heady stuff as the long-running theological debate 'how many angels can fit on the head of a pin?' All 'parallel universe' theories are absolutely untestable, and hence unverifiable, and ...

[quote="harry"]Hello all Re the link: http://antwrp.gsfc.nasa.gov/apod/ap060301.html It states that :"Some multiverse hypotheses may therefore be great fun to think about but not practically falsifiable and therefore have no predictive scientific value" I think the APOD gives us ...

Re: multiverse

[quote="ta152h0"]I agree, it belongs to the other APOD ( Astrology Post of the Day ). I remember the physics professor telling our class that if you can't assign numbers/units of measure to it, it doesn't exist .[/quote]
