NASA Releases a five-year time lapse video of the Sun that uses 2,600 Terabytes of data:
Which brings to mind the videos that zoom out and in from Earth to the known universe, where each circle represents a scale factor of ten (I like watching from 2:33 onwards):
Recently I was reading MIT professor Alan Lightman’s Accidental Universe, a lay introduction to modern developments in physics and some of the emotional, philosophical, and religious questions they raise.
In particular, I wasn’t familiar with some of the think around the multiverse–that this is just one of many existing universes where different laws of nature may apply.
If the multiverse idea is correct, then the historic mission of physics to explain all the properties of our universe in terms of fundamental principles—to explain why the properties of our universe must necessarily be what they are—is futile, a beautiful philosophical dream that simply isn’t true. Our universe is what it is simply because we are here. The situation can be likened to that of a group of intelligent fish who one day begin wondering why their world is completely filled with water.
That uncertainty also disturbs many physicists who are adjusting to the idea of the multiverse. Not only must we accept that basic properties of our universe are accidental and uncalculable. In addition, we must believe in the existence of many other universes. But we have no conceivable way of observing these other universes and cannot prove their existence. Thus, to explain what we see in the world and in our mental deductions, we must believe in what we cannot prove. Sound familiar?
So even the zoom out and in above is a fraction of what exists.
Some people find more comfort in philosophy and religion as a result, but I find much, much less.
