I did a search on the forums and only saw older partial references to this. Things have changed a little and I thought this hypothesis felt satisfying and worth debating further. A summary, from my limited understanding - Universe continues to expand. Black holes become dominant and eventually consume everything. Hawking radiation slowly leaks away from each black hole until they evaporate. That leaves a universe full of mass-less energy particles that experience neither time or distance. What does that mean for space-time? Does that even have meaning in this case? Does location have meaning? Isn't that effectively a singularity - > another big bang? Rinse and repeat. The gist is that the next big bang doesn't wait for all black holes to evaporate but that there is a threshold level of particles that triggers a big bang. That means there will be many black holes still in existence as a new big bang occurs. Part of Roger Penrose's new suggestion is that it should be possible to detect these block holes from the previous aeon in the CMB map. As I understand relativity this seems like a meaningful proposition for a cyclic model.
Shouldn't you have put this in 'Alternative Theories' since this is not a mainstream idea? I think that is the exact opposite of a singularity.
This is nonsense, something called thermal death or the big rip happens after the evaporation of those singularities.
at time mark 1:50 the music directly conflicts with the voice. it is VERY annoying. deliberately done to annoy the listener and put people off ? whom ever was editing this and putting the music on forgot that people WANT to listen to what Roger is saying i stopped the video at that point and will not watch any further.
It says nothing about any cyclical universe or more BB's. At best and briefly...[1] the universe continues to expand...[2] As the mass/energy density gets less with expansion, the expansion accelerates...[3]Galaxies get further and further apart...[4] WD'S and Neutron stars become black cinders...[5]Stars die and no more fuel for more nuclear fusion [6]BH's become dormant [7] Matter left decomposes and all the forces relating to such are overcome [strong nuclear etc] to original fundamentals...[8] BH decay via Hawking Radiation...[9] Possible [but uncertain] proton decay ... [The discovery of DE and the accelerating expansion has seen any thoughts of recollapse evaporate so to speak.] And in the meantime space keeps expanding
