Discussion Overview

The discussion revolves around the origins and sources of dark energy, dark matter, and phenomena related to the Big Bang, including the possibility of external influences beyond our universe. It explores theoretical perspectives and the validity of speculative theories in cosmology.

Discussion Character

  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants question whether the sources of dark energy and dark matter must originate from within our universe, suggesting that external sources could still be a possibility.
  • Others assert that everything occurring in our universe must derive from within it, emphasizing the definition of "universe."
  • Concerns are raised about the prevalence of speculative theories in cosmology, including ideas such as black hole gateways, wormholes, and multiverse theories, with a preference expressed for more rigorous scientific approaches.
  • There is a call for references to credible sources, such as textbooks or peer-reviewed papers, to support claims about speculative theories.

Areas of Agreement / Disagreement

Participants express differing views on the necessity of internal versus external sources for cosmological phenomena, with no consensus reached on the validity of speculative theories in the field.

Contextual Notes

Some claims are based on personal opinions about the quality of theories in cosmology, and there is a noted lack of references to support these opinions. The discussion reflects a mix of skepticism towards speculative ideas and a desire for more concrete scientific grounding.

Discussion on the source or cause of Dark Energy Dark Matter et al
I have had this question for a number of years now.

As a general principle, is there a consensus on whether the SOURCE of dark energy, dark matter, the BB and any or all other similar phenomenon must already be present in our physical Universe (type 1 Multiverse included)?

Or do we not know and as such external sources, beyond our Universe, for some of these are still on the table so to speak?

There is no such thing.

Thanks Peter, so the source of everything which has ever happened in our Universe comes from something already within our universe.
I like to think so also but there are so many speculative theories out there, which I personally do not like.

That's what "universe" means.

Do you have any actual references to textbooks or peer-reviewed papers? There's lots of garbage on the Internet, sure, but that doesn't mean actual scientists pay attention to it.

I mean all these speculative pseudo-science things which have crept into the Cosmology field like where the energy for the BB came from, black hole gateways, wormholes, time travel, Multiverse theories, cyclical universes, branes, string theory. etc etc.
For me some of this is not that far above the techno babble on Trek :)
I want more hard science these days, even if there is a theoretical component.

Again, do you have any actual references to textbooks or peer-reviewed papers? If you do, you can start a new thread in the appropriate forum discussing such a reference and asking questions about it. Vague complaints about stuff you don't like are pointless and off topic here.
 
The OP question has been answered. Thread closed.
