Negative matter is possibly a dark matterDark matter self does not emit light, and does also not interact with light. In the negative matter there is the negative photon, which possesses negative energy and negative mass, and is repulsion with general matter, so the negative matter is invisible.
Just so, is dark matter harmful?
But more-massive pieces of dark matter known as macroscopic dark matter, or macros, could lurk in the cosmos. In theory, macros could directly interact with physical objects such as human bodies, causing "significant damage," according to the new study titled "Death by Dark Matter."
One may also ask, can antimatter destroy dark matter? When matter and antimatter meet they destroy one another in powerful explosions—so when two regular WIMPs collide, they would annihilate one another. If dark matter is made of regular WIMPS, when two WIMPs meet at the center of a star they would destroy one another, because they are their own antimatter counterparts.
Considering this, is Negative matter possible?
Washington State University physicists have created a fluid with negative mass, which is exactly what it sounds like. Hypothetically, matter can have negative mass in the same sense that an electric charge can be either negative or positive.
Do we have dark matter in our bodies?
Every second, you'll experience about 2.5 × 10-16 kilograms of dark matter passing through your body. Every year, approximately 10-8 kilograms of dark matter move through you. And over the course of a human lifetime, a total of just under 1 milligram of dark matter has passed through you.

How expensive is dark matter?
1 gram of dark matter is worth $65.5 trillion. What would happen if I touched antimatter?
Whenever antimatter meets matter (assuming their particles are of the same type), then annihilation occurs, and energy is released. In this case, a 1 kg chunk of the earth would be annihilated , along with the meteorite. There would be energy released in the form of gamma radiation (probably). How strong is dark matter?
Dark matter is a form of
matter thought to account for approximately 85% of the
matter in the universe and about a quarter of its total mass–energy density or about 2.241×10

Is dark matter useful?
Understanding dark matter is important to understanding the size, shape and future of the universe. The amount of dark matter in the universe will determine if the universe is open (continues to expand), closed (expands to a point and then collapses) or flat (expands and then stops when it reaches equilibrium). Can Dark Matter give you powers?
In the game series Mass Effect, dark matter is manifested in the form of a substance called "Element Zero", which is informally referred to as "eezo". In DC's Flash, all the things are about the Dark Matter which gives human superpowers. How dangerous is antimatter?
A gram of antimatter could produce an explosion the size of a nuclear bomb. However, humans have produced only a minuscule amount of antimatter. If all the antimatter ever made by humans were annihilated at once, the energy produced wouldn't even be enough to boil a cup of tea. Can you see dark matter?
Although we cannot see dark matter and we have not yet detected it in a lab, its presence is made known through gravitational effects. Based on theoretical models of the universe, dark matter accounts for nearly five times as much of the universe as does regular matter. Why is there no negative mass?
General relativity describes gravity and the laws of motion for both positive and negative energy particles, hence negative mass, but does not include the other fundamental forces. Why is force of gravity negative?
Any object affected only by gravity (a projectile or an object in free fall) has an acceleration of -9.81 m/s2, regardless of the direction. The acceleration is negative when going up because the speed is decreasing. The acceleration is negative when going down because it is moving in the negative direction, down. Is a black hole negative mass?
The resultant exterior black hole spacetimes necessarily have negative mass and non-trivial topology. A full theory of quantum gravity, in which topology- changing processes take place, could give rise to such spacetimes. Can weight be negative physics?
Weight is a vector quantity so it can be either positive or negative, with respect to reference it can be positive or negative. Is negative gravity possible?
Under general relativity, anti-gravity is impossible except under contrived circumstances. Can negative mass travel faster than light?
Particles with negative mass squared are called tachyons, and they always travel faster than light. Is dark energy negative energy?
Dark Energy is a hypothetical form of energy that exerts a negative, repulsive pressure, behaving like the opposite of gravity. Who proved Tachyon is faster than light?

Does anything have negative density?
In theoretical physics, negative mass is a type of exotic matter whose mass is of opposite sign to the mass of normal matter, e.g. −1 kg. Currently, the closest known real representative of such exotic matter is a region of negative pressure density produced by the Casimir effect. What would happen if antimatter hit a black hole?
When equal amounts of matter and antimatter collide, they are annihilated. The two would be annihilated and turn into pure energy. Of course, the gravity of a black hole is so immense that nothing, not even light can escape. What is antimatter bomb?
An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon. Annihilation requires and converts exactly equal masses of antimatter and matter by the collision which releases the entire mass-energy of both, which for 1 gram is ~9×1013 joules. Is there antimatter in black holes?
Given that there is about 700 times as much normal matter as there are black holes, this can't be where the antimatter is hiding; antimatter didn't form black holes. If you want something to affect the antimatter in the Universe, it must also affect matter. Can you create dark matter?
One leading hypothesis is that dark matter consists of exotic particles that don't interact with normal matter or light but that still exert a gravitational pull. Several scientific groups, including one at CERN's Large Hadron Collider, are currently working to generate dark matter particles for study in the lab. Is dark matter and antimatter same?
Two of the most intriguing mysteries in modern cosmology are the apparent preponderance of ordinary matter over antimatter and the nature of dark matter, which accounts for about 85% of the mass in the Universe1. Dark matter has made its presence known only through its gravitational effects on astrophysical objects. Does antimatter destroy matter?
What makes antimatter unique is that when antimatter comes in contact with its regular matter counterpart, they mutually destroy each other and all of their mass is converted to energy. This matter-antimatter mutual annihilation has been observed many times and is a well-established principle. How destructive is dark matter?
When dark matter is destroyed, it leaves behind a burst of exotic particles, according to theory. When two dark matter particles collide they can sometimes destroy each other and release a burst of energy that includes positrons. How much antimatter would it take to destroy the earth?
How much antimatter would our villain need to annihilate with "normal" matter in order to release the amounts of energy required for the destruction of Earth? Lots! Approximately 2.5 trillion tons of antimatter. Can matter be created?
Water is composed of two hydrogen atoms bonded to an oxygen atom. Photograph by OJO Images Ltd. From port-a-potties to supernovas, matter makes up everything visible in the known universe. Because matter is never created or destroyed, it cycles through our world.
