Partially due to the fact that it was my first idea, Ultramatter is my pet theory. I came up with it in 8th grade, and have been working on it ever since. I have talked to anyone who would talk to me about it, including Dr. Jerry Burns, a college chemistry professor and Dr. Tomov, who works with people that manipulate atomic particles.
When I first learned the structure of an atom, I took particular note of the fact that an atom is mostly empty space. To be precise, a Hydrogen atom is 99.9999999999996% empty space (and the amount of empty space will increase exponentially with each new electron shell). That got me thinking. What if you could collapse the electrons into the nucleus without destabilizing the atom, creating a nucleus with a net charge of zero? In most cases, this would result in a pile of neutrons, which would be highly radioactive, and unstable. But if you stripped the area of neutrinos, no neutrons would form, and you would be left with separate protons and electrons. There is still a lot I haven’t learned about neutrinos, so this part of the idea is a bit unstable.
So now that you can make a ball of protons and electrons, you would get them close enough that Strong force would take over, and bind them into a single entity. This is condensing matter into its densest state (without going into quantum theory, which I don’t know almost anything about yet). For example, if Earth were made entirely of Hydrogen (which has less empty space than any other atom, with the possible exception of Helium), and there was no space between atoms, you could shrink it down to a sphere 200 yards in diameter. This is the largest it could be. There are so many other sources of empty space that this eliminates (multiple electron shells, space between atoms in molecules, space between molecules, and maybe more), that it would be more realistic to say that you could shrink Earth down enough that it would fit in your hand.
Now, there are many problems with this, like the massive amount of energy in atoms, the fact that (as far as I know) we have no way of manipulating neutrinos, and the amount of mass required to make a useable quantity, but there are ways of remedying or lessening these problems. With the amount of energy in atoms, the slightest mistake in collapsing the electrons into the nucleus (I’m talking about mistakes in the range of billionths of percents) the atom could destabilize and make a rather large explosion. However, if the atom was supercooled (the last time I checked, we had cooled a material to one ten billionth of a Kelvin), it would be more stable, and the electrons would be moving much more slowly, allowing for both easier manipulation and greater forgiveness. Also, modern science does have ways to manipulate subatomic particles, though I do not know to what extent. I would not be surprised if we figured out how to manipulate neutrinos. As to the amount of mass required, well, I don’t know how to get around this. Hopefully someone will invent a wormhole and we can get matter from other bodies in the universe.
Of course, this would be a very dangerous material, because of its high amount of gravity. As a result, I have come up with an idea for a gravity shield to contain it.
Some uses for this would be for experimentation with black holes (because you could easily create a black hole with Ultramatter), energy production (because it would turn any material that got close enough to it into more Ultramatter, releasing quite a lot of energy—similar to an actively feeding black hole. Maybe I’ll do a post on that later.), or as a weapon of war (I have combined my Ultramatter idea with my gravity shield idea to make a handheld weapon that can implode anything).
