Fast solutions for complex problems

Why did matter win over antimatter?

So why is there far more matter than antimatter in the universe? The Big Bang should have created equal amounts of matter and antimatter in the early universe. Matter and antimatter particles are always produced as a pair and, if they come in contact, annihilate one another, leaving behind pure energy.

Why does matter and antimatter annihilate?

Like lovers caught in a doomed relationship, matter and antimatter initially attract (thanks to their opposite charges) and then destroy each other. Because these annihilations produce radiation, scientists can use instruments to measure the “wreckage” of their fatal collisions.

Does anti matter exist?

Antiparticles are created everywhere in the universe where high-energy particle collisions take place. Antimatter may exist in relatively large amounts in far-away galaxies due to cosmic inflation in the primordial time of the universe.

Can matter be destroyed by antimatter?

The key is that our universe is mostly made of regular matter, so antimatter cannot stick around for very long. Very soon after antimatter is created, it bumps into regular matter and gets destroyed again.

What if antimatter won?

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.

What happens if antimatter touches matter?

Antimatter is the stuff of science fiction. Antimatter particles are almost identical to their matter counterparts except that they carry the opposite charge and spin. When antimatter meets matter, they immediately annihilate into energy.

Is antimatter the most expensive thing in the world?

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 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. So all energy would just be turned instantaneously into more black hole.

How big of an explosion would a gram of antimatter make?

A gram of antimatter could produce an explosion the size of a nuclear bomb. However, 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.

What does antimatter actually look 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. …

What is the 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.

Does NASA have antimatter?

A NASA spacecraft discovers antimatter bursts released by thunderstorms. And now scientists have discovered that these flashes also create the asymmetrical opposite of matter—antimatter. NASA’s Fermi Gamma-ray Space Telescope was designed to monitor gamma rays, the highest-energy form of light, in outer space.

Why do some things decay faster than others?

It all depends on what’s in our trash bins. For billions of years, microbes have been munching on plants and animals. They’ve also had some help from fellow decomposers, like worms, flies, and fungi. The environment where they work can also speed up or slow down the process.

Why do plants and animals decay so quickly?

Most environments exposed to the open air are in contact with plenty of oxygen, so the soft tissues of dead organisms, whether plants or animals, decay quickly. Many, if not most, underwater environments also have a lot of oxygen, since water can dissolve oxygen from the atmosphere.

Are there living things that break down things?

There are a lot of living creatures in nature that help break down things. In fact, our trash cans are almost like an all-you-can-eat-buffet for tiny creatures called microbes. Well, an almost all-you-can-eat-buffet. There are some things that they can’t really feast on. It all depends on what’s in our trash bins.

Why are hard parts more likely to become fossils?

The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts. Hard parts also decay more slowly than soft parts, giving more time for them to be buried.
