Since the earlier conversation had been math related, I thought of the "multiple universes" concept....I am of the old school, in that there is one UNIverse, with perhaps billions of Galaxies, and unknown how many stars, planets, moons, etc in each Galaxy....and no one really knows how big the Universe really is... But Hubby is a real student of Physics, and Quantum Physics in particular, and he thinks it is possible that there are an infinite number of Universes.
However, when Linde talks about "our" universe, I don't see how he can know for sure what is in this, "our" universe.
Heck, do we even know what is happening, Life-wise, even in our own Solar System, or bigger that that, our own Galaxy?
I will say though, that when things get as "knocked out wacko" as they seem to be on our own Earth, it is interesting to wonder if other planets in other Solar Systems, in other Galaxies, and perhaps, even in other Universes' are as messed up as ours.
One, explained Linde, is that the multiverse solves the problem of why the laws of physics in our universe seem to be fine-tuned to allow for life. “If you change the mass of the proton, the charge on the electron,” or any of an array of other constants, “we’d all be dead,” he argued. |
