Quick Answer: What is antimatter?

What is antimatter used for?

Antimatter is used in medicine. These are injected into the bloodstream, where they are naturally broken down, releasing positrons that meet electrons in the body and annihilate. The annihilations produce gamma rays that are used to construct images.

What exactly is antimatter?

Antimatter refers to sub-atomic particles that have properties opposite normal sub-atomic particles. ( Image credit: Katie Bertsche) Antimatter is the opposite of normal matter.

What is antimatter cost?

Right now, antimatter – with a price tag of about $62.5 trillion per gram – is the most expensive substance on the Earth.

What would happen if we 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).

Why antimatter is so expensive?

Due to its explosive nature (it annihilates when in contact with normal matter) and energy-intensive production, the cost of making antimatter is astronomical. CERN produces about 1×10^15 antiprotons every year, but that only amounts to 1.67 nanograms.

Can antimatter be used as a weapon?

Antimatter weapons cannot yet be produced due to the current cost of production of antimatter (estimated at 62 trillion dollars per gram) given the extremely limited technology available to create it in sufficient masses to be viable in a weapon , and the fact that it annihilates upon touching ordinary matter, making

What antimatter looks like?

PHYSICISTS have made a key measurement of anti-atoms, and found that they look just like atoms. Antimatter particles are the same as matter particles, but have the opposite electrical charge.

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 we see antimatter?

Most matter observable from the Earth seems to be made of matter rather than antimatter . The presence of the resulting antimatter is detectable by the two gamma rays produced every time positrons annihilate with nearby matter.

How much does it cost to make 1 gram of antimatter?

Creating Antimatter: At present, antimatter costs $62.5 trillion per gram. Projected improvements could bring this cost down to $5 billion per gram and the production level up ten times from 1.5*10^-9 to 1.5*10^-8 grams (from 1.5 to 15 nanograms).

How much is a gram of dark matter worth?

1 gram of dark matter is worth $65.5 trillion .

What does antimatter explosion look like?

A matter- antimatter annihilation (the technical term) would be very, very bright, assuming a large enough quantity (closer to . 01 grams than to 1 atom). When matter and antimatter annihilate, the product is photons of various wavelengths. Some would be visible light, reaulting in a blinding flash.

What would happen if antimatter hit a black hole?

No. Antimatter has positive mass just like ordinary matter, so the black hole would merely get larger and heavier. Whatever fireworks happened inside the hole , if the anitmatter met up with ordinary matter there, would have no effect on the hole’s total matter-and-energy content or, therefore, its mass.

Can we use antimatter as fuel?

Antimatter is an ideal rocket fuel because all of the mass in matter/ antimatter collisions is converted into energy. Matter/ antimatter reactions produce 10 million times the energy produced by conventional chemical reactions such as the hydrogen and oxygen combustion used to fuel the space shuttle.

Is dark matter antimatter?

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.
