Does this explain the bullet cluster? If it doesn't, it's kinda useless.
(Quote by the author of the study himself)
It's a purely mathematical construct that could explain bending of light without mass.
Typical, scientist: "My paper does NOT say THIS". Press: "Scientist claims THIS!"
Sure, I'm blaming the concerned journalist(s) here. It's rlly scummy to hype up an evidenceless hypothesis like this. Does injustice to both, the scientists and the public.
To be fair dark matter is a purely mathematical construct to explain the presence of gravity without (visible) mass. Certainly dark matter has more credibility than this new idea but hypothetical mathematical constructs make up a good chunk of physics.
But per the definition given involving negative mass, it should be "meassurable mass in the presence of exotic matter". Anywho...
I mean, cool to prove a theory of massless gravity though, whatever their motivation.
You say that about everything
