McGrath of Harlow BS: Something fundamental is missing (Neg. mass) (46) RE: BS: Something fundamental is missing (Neg. mass) 20 Dec 20

Trying to conceive of what "negative mass" could mean is bewildering. You could conceive a kind of particle that would repel "ordinary" particles gravitationally rather than attract them. (Which evidently isn't how it works with "
standard" anti-matter.) But that's only what aspect of 'mass" - and since it's not really right to think in terms of gravity "attracting. But rather of distorting space it's hard to conceive how "repulsion" could translate into that way of seeing it.

"Bewildering" is an understatement.
