Time keeps on slipping, slipping, slipping into the future ...

Treehugger has a long and interesting take on the distant future. Reminds one of H. G. Wells' The Time Machine as he delves into this topic as well. Enjoy. It's worth a read for sure.

The near ...

The end? 

1010^10^76.66 years: Second (uni)verse, same as the first?

The universe may be in ruins, but given enough time, some futurists think something incredible will happen. It's like an endless string of poker games: Eventually you'll be dealt the exact same hand many times. According to 19th-century mathematician Henri Poincaré, quantum fluctuations in a system with fixed total energy will also re-create similar versions of history over inconceivable time scales. In 1994, physicist Don N. Page estimated the duration of "Poincaré recurrence time," describing it as "the longest finite times that have so far been explicitly calculated by any physicist."

Even if dying black holes leave nothing behind, however — and if quantum quirks don't grant us a cosmic mulligan — many physicists and philosophers still think nothing might actually be something. As astrophysicist Neil deGrasse Tyson said in 2013 during a debate on the nature of nothingness, "If laws of physics still apply, the laws of physics are not nothing."

In other words, we have nothing to worry about.

Quite a trip, is it not? :)
