Interesting youtube video: https://www.youtube.com/watch?v=h-ZmwHOUAlw

I really like this idea. It is interesting to consider what happens when the last mass particle of the universe ceases to exist (due to evaporation of the last black hole). If the universe eventually contains no mass and only energy, the concept of time ceases to exist. What was a gigantic space-time volume shrinks to zero along the time axis - a singularity. All the energy (however ‘sparse' we might have measured it to be distributed previously) suddenly occupies zero spacetime, resulting in the next epoch, and the big bang cycle repeats with a new universe.

Thoughts?

Another one that expands on the idea (if you'll pardon the pun): https://www.youtube.com/watch?v=nTMaUlzMeag

interesting link, Roger Penrose has been much debunked by the scientific establishment over the last 10 years. Considering history and great steps forward in understanding this is not unusual, many of the greats were humiliated when challenging the establishment.

I would like to see more open minded thinking around the unexplainable; dark energy, quantum duality, even a rational understandable explanation of the double slit experiment....I know how its explained today, it just doesn`t feel right to a layman.

Ever bigger accelerators have become symbols of national pride, just how much further can you go smashing things up to re create the after effects of the big bang. I guess anyone postulating a different theory as Penrose does is treading on too many toes

As an aside, Penrose talks about black hole evaporation quite casually, a reasonable sized black hole will evaporate in 2x10 100 years, given our cosmos has been in existence for only 13.6Bn years, that`s like comparing one second to a trillion trillion trillion trillion trillion trillion trillion trillion years, mind you the expansion of the universe can be explained by known physics back to Plank time, which is a fair old chunk in the other direction
