Re: Neutron Stars: Total Compaction?
The one question I was hoping someone could answer is: Is it possible that dark matter interacts in our universe gravitationally as the electro-magnetic wave phenomena we call light? The original reason this question came to my mind was that I could conceive light as “something” that was moving thro...

Re: What if the Chelyabinsk meteoroid had been a mini black
Let me guess. We would have seen a lot of Russians videotaping it - forever (at the edge of its event horizon) Just kidding. How about a gamma ray burst?

Re: Neutron Stars: Total Compaction?
electrons and protons combined to form the neutrons Does this reaction need a neutrino too? But back to “Where’s the space?” again. I wonder to where the space left over from the electron shells goes? Guess that must be why the universe is getting larger. :lol2: Heisenberg certainly thought it had ...

Re: Neutron Stars: Total Compaction?
At this scale, it is probably better not to think in terms of "substance" or "matter" or "material", but rather in terms of fields and field carriers. Fields and field carriers do seem to be the language that defines space and allows the forces to be characterized. I’d...

Re: Neutron Stars: Total Compaction?
But I'm not sure space can be ionized.... I was not thinking that space is ionized; just that the area outside the nucleus of an atom (even devoid of electrons) may have a unique characteristic that has not been totally defined. Also, I was hypothesizing that it could be further elucidated whether ...

Well, there goes that delusion. It obviously doesn't add the gravity to my idea. Unless there is also a version of dark matter that adds to gravity but not to overall mass. Although light is affected by gravity curiously...

Re: Neutron Stars: Total Compaction?
I'd have to admit that's true. My understanding of the short-lived particles is that they can be created in a vacuum. But doesn't space exist even in a vacuum? I think of space as the area between points or groups of matter. That light travels through vacuum faster than other matter only fuels my de...

Re: Neutron Stars: Total Compaction?
Space seems to be the one intangible aspect of our physical experience we have trouble understanding. Quantum theory (the little I understand) depicts it to contain short-lived particles. Since we haven’t found dark matter, as far as I know, I frequently am curious if it is part of the emptiness als...
