They say atoms are electrons protons neutron quarks and squarks but what kind of substance is it ?

Question

Did any thinking scientist ever question what the substance of an electron is?Defining by what does not really exist?Every thing is massless substance?This is soo confusing.

I wish I was a guitar payer to understand string Theory.

Answer 1

Its matter. But what is matter. String theory suggest that all matter is made up of vibrating string and the different vibrations causes different characteristics in matter.

Answer 2

What kind of substance? It isn't a substance at all, it does not make sense to talk about a substance. Think of it a bit like when you push the "wrong" ends of two magnets together, you know, when they push apart and don't want to touch?

In that case, there are no substances touching, and no substance in the space in between, but you can tell that there is something there... if you have a few in a row, you could count them by sliding over the "bumps".

The same is true about subatomic particles. What is important about them is how they affect each other.

When your brain processes the information that it gets from your eyes, it creates in your mind a mental image of what "substances" are in the world around you. And when your finger reaches out and tries to touch the subtances that make up the table in front of you, what actually happens is a bezillion little interactions like the two magnets pushing together. The "substance" of your finger never actually "touches" the "substance" of the table, and none of it "looks" like the picutre you create in your mind. It is just convenient to think of it that way.

Or if you want, you can define the word substance to be the imaginery thing in your head, and you can define "touch" to be the imaginery action in your head.

But the same subatomic particles you are asking about in your question are involved, and they don't rub against each other, their properties simply interact with each other, just like those magnets that don't actually touch each other but push apart from a small distance. If you consider what we know about quantum mechanics, it is even more imagery than this: an electron does not exist in a place, there is a little "cloud" of places where it is likely to be.

There are some theories of the universe that say all these particles don't exist, they are just numbers in a big "computer-like-thing" that exists in another dimension, and the program running "calculates" from the numbers what happens, like in a video game or a big giant spreadsheet.

Good question, though!
