Dark Matter/Dark Energy.
Dark matter holds us all together. Dark Energy wants to break us apart. Good reason to go bang?
In any explosion there is always a remnant to tell detectives what explosives caused the blast. Where was Dark Matter and dark Energy during Plank time? Scientists are now starting to talk about multiple universes, The time before the big bang.
What caused it? Iv,e seen photos with universes connected like DNA strings. Flat universes, bow shaped, spheres. etc etc.
If there was 2 entities that came together, could Dark Matter and Dark Energy be a Remnant of before the big bang?

Re: DM/DE, Remnant.
Not a very good comparison, IMO. Dark matter is just that... matter. If you want to contrast something to dark energy, it should be gravity. Gravity manifests as an attractive force, DE as repulsive a force. Even without DM, matter would hold together.mark swain wrote:Dark matter holds us all together. Dark Energy wants to break us apart.
Dark energy is so poorly understood (except in its actions) that its history is basically unknown. I think most theorists would consider dark energy to have developed after the Planck time, however. Dark matter is better understood, and most likely formed from the primordial energy quite some time after the BB, like other forms of matter.Where was Dark Matter and dark Energy during Plank time?

This is interesting. You learn something every day

Re: DM/DE, Remnant.
Quite true. One of the major efforts in modern astrophysics is to try to constrain the history of dark energy as best as possible with new and different astronomical measurements. With a student, I once wrote a summary of cosmologies that prominently discussed dark matter and dark energy that was published in the American Journal of Physics which may help in understanding and which I will shamelessly plug here:Dark energy is so poorly understood (except in its actions) that its history is basically unknown.

Re: DM/DE, Remnant.
Thanks for the information, RJN . Very much Appreciated.
I very much like your use of the term "Fluid Energy" . Like we see in the 'roll' of water. It plays many parts.
I will Enjoy studying this.
Thanks
Mark
