What are the potential applications for negative mass and energy?

>> No.10589185

>>10589113
negative mass would be pushed away from our universe
negative energy means, there would be energy absorbed instead of released?

>> No.10589196

>>10589113
stabilizing wormholes

>> No.10589203

neither mass nor time can have negative sign
they are just too real and fundamental

So, a black hole?

>> No.10589213

>>10589203
can't imagine a body that releases energy once it's motion is changed?

Hawking radiation is still hypothetical and has not been proven by observation.

>> No.10589253

>>10589237
Hawking radiation has actually been detected when CERN made small black holes.

I've seen imaginary signs on mass.

Black holes collect energy, they don't absorb it.

They were blips, anon.

The black holes evaporated into hawking radiation.

Think what mass and energy do. Now imagine what would happen in the reverse.

>>10589185
energy (Also depends on what energy you are talking about.) isn't released so it can't be absorbed.
>>10589196
Maybe
>>10589197
Look into Elementary particles & forces
>>10589203
mass and time are two different things.

Too all talking about black holes. They "absorb" certain types of energy. They can emit energy in different forms. If a black hole rotates and you can somehow escape its escape velocity (Can't remember the proper term). Then in that instance it has released energy.

Everyone is using the term energy as a all encompassing term when it isn't.

Hypothetically something could have negative mass and 1. We can't detect it 2. It exists in a different spacial dimension independent of our own 3 spacial & 1 time.

Negative energy can have the same problems as above. Maybe think of negative energy as a magnet and ponder on that.

From your statement it seems your treating negative mass and energy as opposites of mass and energy and I don't think that is correct way to look at it.

Perpetual motion. We can get unlimited positive energy by producing negative energy at the same time and shooting that beam of negative energy away. 1 - 1 = 0, so we don't violate thermodynamics

But... negative mass would be able to be converted into negative energy, because mass is energy.
