Re: Five mysteries of the Universe
There is no mystery.
All of you, the universe, all the other universes, dark matter, dark energy, etc are just figments of my imagination.

These things have all the attributes of faith based philosophy. One can imagine all manner of things, one can construct mathematics based on these imaginations, but with out experimental evidence then it is all beautiful stuff, but it is not physics which is concerned with what we can measure.
In the by & by some of these imaginations may become a measured reality, or some new theory may replace them.
The ideas of Aristotle lasted around 1500 years, then Newton thought & the understanding of the world changed.

More like Galileo and Tycho Brahe made measurements and Kepler and finally Newton explained those measurements and came to a new understanding.

And then Michelson & Morley made some other measurements and Einstein said, "Pretty good try Newton, but not quite" and explained those measurements and came to another understanding.

Re: Five mysteries of the Universe
...and then Roger Penrose came along to say that the eventual 'death' of the universe - where nothing is left but widely dispersed photons - is mathematically the same as whatever exploded into the (next) Big Bang, and that there may be experimental evidence* (Hawking Points) to back it up.

It is interesting that where Penrose predicts that there should be evidence of a previous universe there is experimental data consistent with his conjecture, but most physicists are skeptical & disbelieve the analysis. As far as I know no one has explained what is the source of the observations if Penrose is wrong. Does anyone have more formation on this?
