Question: Are There Antimatter Galaxies?

How much antimatter does it take to destroy a city?

You’re looking at 1–2 kg for the centers of London or LA.

You’re looking at more like 5–10 kg to destroy the whole urban area..

How much does it cost to make 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).

Can antimatter be dark matter?

Dark matter is considered not to be “regular” matter, of the kind that makes up cats, smartphones, and stars. … On the other hand, antimatter, a staple of science fiction, conjures exotic images but is actually regular matter.

Who stole anti matter?

MatterMatters Corp.The anti-matter was stolen from a research company, MatterMatters Corp.

Could there be an antimatter universe?

Antimatter may exist in relatively large amounts in far-away galaxies due to cosmic inflation in the primordial time of the universe.

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.

Why is antimatter 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 destroy a black hole?

No. As you may know, antimatter has mass just like matter, but all the properties (charge, spin, etc) are reversed. In normal space (that is, not inside a black hole), when matter and antimatter meet, they mutually annihilate each other, releasing a burst of energy.

Does antimatter take up space?

Antimatter also has mass and takes up space. However, when they meet, matter and antimatter tend to destroy one another with a tremendous release of energy.

Why is antihydrogen so expensive?

In 1999, NASA gave a cost estimate of $62.5 trillion per gram of antihydrogen (equivalent to $96 trillion today), making it the most expensive material to produce. This is due to the extremely low yield per experiment, and high opportunity cost of using a particle accelerator.

Is Antimatter more powerful than nuclear?

Antimatter is nearly 10 times more powerful than the most powerful nuclear weapons, due to the fact that nuclear reactions only release 10% of their energy created as the blast itself. Antimatter, being antimatter, gives all 100% as the explosion. … One gram of antimatter has yield of 40 kilotons.

What happens if antimatter touches matter?

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).

Where is antimatter kept?

The only way to store antimatter, then, is to keep it in a magnetic field. Until very recently, that meant that only subatomic antiparticles could be stored and studied because only charged antiparticles, antiprotons and positrons, can be manipulated by a magnetic field.

What would an antimatter universe look like?

What if anti-atoms gravitationally repelled each other? In that case, an antimatter universe would never form stars or galaxies. Our antimatter universe would simply be filled with traces of anti-hydrogen and anti-helium, and nothing would ever look up at the cosmic sky.

Can you touch antimatter?

When antimatter and regular matter touch together, they destroy each other and release lots of energy in the form of radiation (usually gamma rays). If it’s a small amount, it’s totally safe. … If it’s a large amount, the gamma radiation would be enough to kill you or cause serious harm.

Can antimatter be used as a weapon?

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.

What is the Colour of antimatter?

If matter antimatter symmetry is perfect, what is trying to check one of the CERN experiments (ALPHA observes light spectrum of antimatter for first time ) then there is no difference in visible colors of antimatter.

What is the antimatter universe?

The Antimatter Universe is an Anti-matter cosmos occupying the same continuum space but on a different space-time level. It’s a counter-world where good is evil and evil is good.

How much antimatter would it take to destroy the earth?

Then, you would need 1.3 x 10^15 kg of antimatter to completely destroy the Earth – a smaller amount could effectively destroy it and a much smaller amount could destroy all sentient life on it.

Which country has antimatter bomb?

GermanyHowever, humans have produced only a minuscule amount of antimatter. All of the antiprotons created at Fermilab’s Tevatron particle accelerator add up to only 15 nanograms. Those made at CERN amount to about 1 nanogram. At DESY in Germany, approximately 2 nanograms of positrons have been produced to date.
