Is the smallest thing in the universe the largest?

Question

compressed material seems to be the largest things in the universe.And when something the size of a pea can weigh more that the sun .or, bigger planet ....what forces commpression gravity ,gravity must be tiny.

Answer 1

That is correct but dark matter can have reverced atoms that make them the lightest thing in the universe so they can at one minute be the heaviest and then the lightest. These materials are created when a black hole sucks in matter and makes it into one object or imense wieght.

Answer 2

Your question doesn't even make sense. "compressed material seems to be the largest things in the universe" Compressed things are smaller unless you mean having something the size of the sun containing the compressed matter of 17 suns. Basically compressed things are smaller than the original.

When you say something the size of a pea can weigh that of a sun that is relative to what it would weigh on earth in space that isn't the case. That kind of matter you are talking about is the material inside a star that implodes in on itself. The force that causes this is gravity and also the chemical reactions that are happening inside the star. When it implodes a lot of what was the star is compressed into a highly dense ball of matter. This is why a small amount of this stuff would weigh a lot on Earth it's a lot of a star in a tiny sample.

Answer 3

You seem to be confusing size, mass and density.Black holes are made of huge amounts of compressed matter and have enormous mass but occupy very little space.So all you can really say is 'does the smallest thing in the universe have the most mass?' in which case yes it probably is a black hole.

However a super massive black hole containing several thousand times the mass of the sun will still have a diameter of at least 1 metre.

So I suppose the real answer for the smallest thing is an atom or subatomic particle.

I dont really understand the last bit of your question but I think you are pointing out that gravitational force that is exerted by all matter is very weak.This is true when you compare it to other forces, however when you get a huge amount of matter as in a black hole then all the little forces add up to something extraordinary which causes the star to collapse in on itself.

Answer 4

i don't think this quite works: smallest thing in the universe is what makes up protons/neutrons/electrons (can't remember the name but check 'A Brief History of Time' - Prof. Stephen Hawking). Largest things in the universe must be a star or a planet. What I think you meant to ask was what has the largest MASS and smallest MASS - to which I do not know :P (no doubt it is mind-boggling!!)

Answer 5

The smallest thing in the universe is a single unit of space.
The largest thing would be the massive stricture that subtends all the matter in the universe.

Answer 6

A better way to state it is that the largest "things" in the universe are made up of the smallest things.

But since EVERYTHING is made of the smallest things, what's the point of stating this?

Answer 7

Indeed some of the smallest things have an incredible effect - like GW Bush's brain for example.

Answer 8

There's a LOT of things in the universe.... Freaking 50? Nope. Here's 10% cosmic string -> quark -> ion -> atom -> compound

Answer 9

If we are talking about universe ; small or largest has no meaning.
But I can say quark = small , sun = big

Answer 10

A string,
