what is kryptonite?

Answer 1

In the Superman comics, it is a radioactive element. The core of Krypton was unstable, that is, it was composed of unstable elements, and there were enormous underground nuclear explosions, causing quakes. Eventually, enough of the core of Krypton was converted to Kryptonite that the whole planet exploded. That was when Superman’s dad sent him to Earth.

(You have to understand, this is the Reader’s Digest condensed version. There were half a dozen varieties of Kryptonite before Crisis on Infinite Earths, and you can look it up on wiki if you want. But since Crisis and the DC reboot, there has only been one variety of Kryptonite, and that is the kind that makes Superman weak and helpless and causes him terrible pain and will kill him if he is exposed to it for long.)

Now, you may have seen on the news just today, that there is a real mineral on Earth which has the same chemical formula as the Kryptonite that was in the Superman Returns movie. The label on the Kryptonite that Luthor stole from the museum gave some chemical formula. The writers didn’t know anything like that existed. So it was a coincidence that a real mineral was found of the same composition. (The real thing is said to be white, not green.)

Kryptonite is supposed to work because Superman is a lot more sensitive to the radiation that everybody else is. It gives him radiation poisoning. Imagine getting a sunburn all through your body, not just on your skin, but all through your internal organs at the same time. That’s what it feels like for him.

It is not good for humans, either. In the comics, Luthor wore a Kryptonite ring to keep Superman away. He got cancer in that hand eventually and had to have it amputated. But our bodies are not dense enough to stop most of the radiation, it goes through us harmlessly for the most part unless we are exposed to it all the time, as Luthor was.

Hope this tells you what you wanted to know!

Answer 2

Kryptonite is an element not of Earth origin. There is a noble gas on the periodic table called Krypton, so there may be a possibility that Kryptonite is a crystalline form of Krypton that makes Superman a mere human. Krypton the planet may have exploded but most fragments would have burned up in the atmosphere. The heat would cause the krypton gas to combine with other elements (highly unlikely because noble gases cannot merge with other elements easily because of their valence electron charge, but possible) and make radioactive Kryptonite.

Answer 3

radioactive shards of the remains of superman's home world krypton. there are a number of diffrent colors/types of kryptonite and they all have various detrimental effects on superman. the two most common in the comics are red kryptonite which makes superman go insane with paranoia, and green kryptonite which is the only known thing that can kill superman.

Answer 4

Well to sum it all up, Kryptonite is a radioactive piece of rock from Superman's homeworld Krypton. It is said to be the Man of Steel's only weakness.

Answer 5

kryptonite are fragments of supermans home planet(krypton), which blew up for some reason (probably caused by Brainiac)
the reason why it makes superman so weak is becouse it emanates a form of radiation that block suns energy from reaching supermans body(sun is superman's source of power)

Answer 6

It's a band, a song, or a green stupid rock that makes superman lose his powers temoraroly..otherwise makes him utterly weak XD

Answer 7

some thing powerful .it must be if it can stop super man
