Is anti-gravity possible?

Question

I want to find out if there really is such thing as ''negative mass''.... ive been really thinking about that....but, it's a bit confusing....first of all, WHAT is negative mass..and does it exist? hpw is it attainable?

Answer 1

Mag-Lev is not the same as anti-gravity. The question is, "Can gravity act as a repellent force, or is it always attractive?".
The answer is that current theories predict gravity can sometimes act as a repellent force. However, this behavior has not yet been directly observed, much less harnessed. Perhaps when gravity is quantized and the elusive graviton has revealed some of its properties, then the truth will show itself. Until then we can do little more than calculate and speculate.

Answer 2

According to theory, every action has an opposite and equal action- thereby anti-gravity (a force, or 'action') is possible. Negative mass is a no - thing . A mass of non-stuff,as it were. It probably is already in existence, but we may not be aware of it, or how it is 'created'- heck, we,for the most part, don't even know how matter is created......altho, MIND can manipulate matter. Something to think about..... Maybe we can alter those nasty substances out there into some nice, life-giving substances....hmmmm

Answer 3

it really is available to be weightless - by using surrendering to gravity and getting right into a loose-fall. Spaceships in the orbit do this, sky divers do this, or perhaps some rollercoaster rides do it, albeit for some seconds. Gravity, although, is between the mandatory forces in the Universe. you won't be able to easily cancel it. you may conquer it with yet another rigidity, yet you won't be able to make it dissapear. in case you should, the completed Universe may likely fall down and stop to exist.

Answer 4

Exotic matter contains negative mass. Exotic matter is something that gravity will push that matter away from an object rather than pulling it. Read more: http://en.wikipedia.org/wiki/Negative_mass

Answer 5

About "negative mass", the jury is still out:

Anti mass -m is never observed.
