Dear Marcus, I think that it is more or less accepted that the most dense black hole is a Planck particle which is at the same time the smallest particle (outside a BH). Larger black holes have densities inverse to their mass. Now my question: in the models, you are referring to, is it assumed...

Observable? Observations on systems near the edge of the (our) observable universe could give information about the observable universes of those systems. Their OU's partly overlap with our unobservable universe (UOU). So IMO our UOU can be indirectly be observed? regards, hurk4

Dear Marcus, thank you for your kind remark. My answer "Existence" was the most general I could imagine, but what can we do we this "non practical" remark, I guess almost nothing. I could eventually fill in more details at the price being speculative. So I could for instance add...

existence, whatever that is! hurk4

Could or did De Sitter foresee in his time that his model was compatible with the acceleration? Can we see from his model how this acceleration works out, e.g. linear or exponential or? kind regards hurk4

Ok, thank you. regards hurk4

Static?, (in an interesting kind of way) Why then t dependent? Regards hurk4

Dear Sylas. As a (math. model): 1) also when this domination is exact 100% ? 2) is it static? 3) is its space-time restricted? regards hurk4

Maybe obvious, but I will ask it here. Is a "De Sitter Universe (as a model) compatible with dark energy, and if so, is it then also compatible with constant-dark-energy-density? kind regards Hurk4

Dear Chronos, Thank you for your reaction which I think is clear to me. I should better stop asking you these questions. Kind regards Hurk4

Dear Chronos, Happy with your assumption! I still have additional questions here. 1) Is it possible to see the couple of spacetime and energy density also as a local entity? 2) Can you then imagine such entities seperately connected to the different kind of existing types of energy? (In...

Dear enotstrebor, Thank you for your post. It is not just in some of the string theories but it is also in other new theories like Loop Quantum Gravity that Planck units are used. In physics forums there are several extended threads discussing Planck units such as "Is the Plancklenght a...

I said "free particle" Once it is located in your detector it is not free anymore and the compton wavelengh has gone. And in that situation I would not give it such a name like Compton particle. Maybe you can explain me what is wrong with this questioning? kind regards hurk4

Dear Matterwave At the Planck mass Compton wavelenght and Schwarzschild radius are about equal. So I suppose at lower mass free particles are compton waves. kind regards hurk 4

Correction: Of course it is proportional to its black hole mass regards hurk4
