What color would antimatter be?

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.

How much antimatter would 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.

What would happen if everything was antimatter?

Fairly large asteroids enter the atmosphere every few months—mostly unnoticed. If they were all antimatter, each one would trigger a tremendous pulse of energy in the sky and ignite a massive firestorm.

Can antimatter destroy a black hole?

The bottom line is: If a regular black hole and an antimatter black hole got black-hole-married in space, they wouldn’t vanish. Feeding in antimatter won’t do any good, it’s just like regular matter or energy. It only makes the black hole more massive.

Where did all the antimatter go?

Matter and antimatter annihilate each other on contact, and researchers believe such collisions destroyed almost all of the antimatter (and a large chunk of the matter) that initially existed in the cosmos.

Are there antimatter galaxies?

Therefore, astronomers conclude that there are not occasional ‘rogue’ galaxies made of antimatter. If there is any large amount of antimatter in the universe, it must encompass at least an entire galaxy cluster, and probably a supercluster.

Can you make Earth’s zero gravity?

As of yet, no technology exists to neutralize the pull of gravity. The best way to approximate the feeling of weightlessness on Earth is to ride onboard a plane flying in parabolic arcs that mimic the shape of Saint Louis’s Gateway Arch.

Is Anti-Gravity theoretically possible?

In the 20th century, Newton’s model was replaced by general relativity where gravity is not a force but the result of the geometry of spacetime. Under general relativity, anti-gravity is impossible except under contrived circumstances.
