At a cosmology lecture some years ago I asked the speaker at the end of the talk if dark energy and dark matter might be “equivalent” as ordinary energy and matter are according to Einstein’s E=mc^2. She answered, without really giving it much thought, no. Then went on to the next person asking a question. I suspect she hadn’t any idea one way or the other.
So we close the book on the search for dark matter and open another on negative mass.
Sounds balanced to me.
> If you were to push a negative mass, it would accelerate towards you. <
Well, that explains my last girlfriend.
Take a cubic meter of space.
Suck EVERYTHING out of it. Get to a theoretical complete vacuum.
Now shine a light through it.
The light passed through that space. No problem.
So was something ‘there’ when the light was in it?
What is a photon passing through, when it is passing through empty ‘space’? Is that space still empty?
People who did not like the Big Bang came up with a steady state model that involved continuous creation of matter. This new paper took a failed idea from 70 years ago and applied it to dark matter/energy.
In 1970, Jean-Marie Souriau demonstrated, through the complete Poincaré group of dynamic group theory, that reversing the energy of a particle (hence its mass, if the particle has one) is equal to reversing its arrow of time.
Negative mass leads to some funky stuff. Who knows? Some of the wild conspiracy theories about hidden science could be right.
There would be quantum virtual particles popping into and out of existence.
“Repelling all other material around them”
Aaahhhhhh.....the Joy Behar phenomenon.
Science always has a fancy term for things we don’t understand. Whether it is “phlogiston”, “ether”, “dark matter/energy” or perhaps now “negative mass” it all means the same thing: “here be dragons”.
How many ranks and orders is that tensor?
I wonder why he felt the need to do a press release.
If the theory passes muster with other physicists we’ll hear about it soon enough.
Space is a fabric.
There is still space in space.
If time exists in a region of space, then that volume contains time-space reality.
But of course. There is always money to be made doing the research in the trade.
God can measure the universe with the span of His hand.
It's finite.
You are assuming Gods hand is finite. ;-)

Interesting 6 minute video about the Big Bang and a book by an agnostic astronomer addressing what it means:
“God And the Astronomer”

95% of the cosmos is missing?
I’ll look in the garage. There’s a lot of stuff out there.
I think the steady state model predates the big bang model.
IOW, FLUBBER!
