Can mass be cancelled or turned negative?

Question

Gravity depends on mass so can we distort an objects gravitational field by manipulating its mass?

Answer 1

There is no such thing as negative mass

There is no such thing as negative pressure

There is no such thing as absolute zero energy. This means that one energy can be negative relative to another.

Gravity is a function of energy and mass. So changing either of these variables would affect gravity.

If you were looking to "cancel" a mass by changing it into pure energy, this is also possible.

Answer 2

You can indeed manipulate gravity through manipulating mass.

However, pressure and energy also affect gravity. There's no way to have negative mass, and no one knows of any way to have negative energy, but you can certainly have negative pressure. Pressure, in the sense im using it, is like a spring in a jack-in-the-box; when you push the spring down inside the box, and close the lid, the spring pushes upwards on the lid.

Answer 3

An objects gravitaional field can be distorted just by moving the object, I think. But to produce a significant amount of distortion, some thing that will produce an observable effect, we will need some thing that is really massive, like a black hole, I would think.

Answer 4

Sorry to pop this no negative energy bandwagon but yes you can have negative energy and therefore negative mass. The simplest way to explain this is through the Casimir effect. Now i'll let you go read up on that yourself as i cant tailor an explanation to all levels of study. But this negative energy theory has been around and proven in 1948. Run a quick search on it it is fairly easy to get your head around. So no more shouting of impossible negative energy please ^_^


and antiparticles are not really negative energy they are only described as being opposites out of convention

Answer 5

Yes,it exists all around us. Take the model of electrons orbiting the nucleus of an atom as an example. If the protrons and neutrons were about the size of peas, the electrons would be orbiting the nucleus about 50 feet away! So what about all that empty space in between? That's negative space! There are things as antiprotons!

Answer 6

Nuclear fusion reaction: Hydrogen nuclei (protons) fuse to create helium-4 and launch potential in distinctive ranges: a million. 2 protons combine to form a deuterium (hydrogen atom with one neutron), a positron (comparable to electron, yet with a favorable can charge) and a neutrino 2. A proton and a deuterium atom combine to form a helium-3 atom (2 protons with one neutron) and a gamma ray. 3. 2 helium-3 atoms combine to form a helium-4 (2 protons and 2 neutrons) and 2 protons. Now, the helium-4 atoms are much less massive than the two hydrogen atoms that all and sundry started the approach. the version in mass replace into switched over to potential given with the aid of Einstein's concept of relativity (E=mc2). Protons are generally happening to rework into neutrons contained in direction of the technique of electron seize. This technique does not ensue spontaneously yet purely whilst potential is provided. in case you like a seen rationalization or extra exact rationalization circulate to the internet sites below.

Answer 7

No such thing as negative mass..however there are these particle called tachyons which travel with superluminal velocity and have imaginary mass.

Answer 8

Mass is canceled in water if there's enough depth.

Answer 9

NO
