I was in a restaurant, and I was thinking about random stuff. Then, my mind reached out and plucked something, I presume, out of my subconscious. I started thinking about black holes, and then a thought came in: "could there have ever been anything that had negative mass? And if there ever was, why isn't it in plain sight now?" Then I realized that if there was negative mass, then the gravitational effect would also be reversed, because of how gravity works (still no idea
why it works.) Then, I thought about Einsteins theory with the space fabric and came back around to black holes. If this is a black hole,

and it sucks everything in, then would something with infinitely negative mass be like this?
_______| |______________
(mind that you think of this on a 3D type way)
and push everything away? Then I got to thinking about how two negatives would attract and stuff like that. I got home, and decided to look this up and see if anyone else had thought along the same lines as me.
Einstein and Newton beat me to it.(I should've known, it seems sometimes, like they both had time-travel/thought-reading machines)
Antigravity and conventional physics
In both Newton's law of gravitation and the general theory of relativity (Einstein's theory of gravitation), a requirement for antigravity to be possible is the existence of negative mass. Most scientists regard negative mass as a purely hypothetical concept with no basis in reality. However, there is nothing in physics to say that it is actually impossible. A related idea that has been discussed by theoretical physicists involves gravitational shielding.

Share your thoughts on this matter :tongue: please.
Negative inertia- How might this work? Things that want to slow down if they're moving and vice versa?
Negative infinitely (un?)dense mass- white
holes hills(in the generic stuff we label as space fabric)?
Negative mass through gravitational shielding- Possible? or not?
What would happen if you had a cup of negative water and positive mass water, and you mixed them.
Is that last question possible, or would you have different elements on the periodic table that go back past hydrogen that are negative.
This would make my science teacher's head hurt, everything else seems to, but I think she just says that without meaning it. Not making any conclusions about that though. anyways, I think it'll be interesting to see what you think on this matter.
BTW: Just wondered what these looked like: ;D
