An expert on the fate of the cosmos and co- author with Greg Laughlin of The Five Ages of the Universe (Touchstone Books; 2000), Adams predicts that all this dead matter will eventually collapse into black holes. By the time the universe is 1 trillion trillion trillion trillion trillion trillion years old, the black holes themselves will disintegrate into stray particles, which will bind loosely to form individual "atoms" larger than the size of today's universe. Eventually, even these will decay, leaving a featureless, infinitely large void. http://www.time.com/time/covers/1101010625/story.html

These are basically particles with wave functions that overlap each other. Due to the properties of Quantum Mechanics, they can span infinite distances, faster than the speed of light. Yousuf Khan

From what I�ve tasted of desire I hold with those who favor fire. But if it had to perish twice, I think I know enough of hate To know that for destruction ice Is also great And would suffice. -- Robert Frost

A few larger ones will go super nova. In either case, their planets are either destroyed or left to aimlessly wander the Galaxy. But the Black Hole at the center of each Galaxy will get its due. Slowly, one at a time, it gravitationally attracts and then devours the hapless remnant spheres of spent fusion glory, until the Black Hole is all that's left of the progenitor Galaxy. One tea spoon of its matter weighs in at millions of tons. These voracious beast are now hunting each other, merging and with growing gravity more are attracted yet. As the Black Hole grows, its sub-atomic particles are crushed together tighter and tighter under ever increasing pressure. Until that final Black Hole joins into the fray, pushing the pressures beyond the repulsive capabilities of the sub-atomic particles, tearing them asunder to even smaller, as yet undiscovered particles of infinitely small stature. The resulting inward collapse of the Black Hole and the subsequent rebound is called "The Big Bang" and so a new cycle in the long history of the Universe begins once again. Perhaps this time we'll get it right ??? |
