Crazy question

Could our galaxie be looked upon as a model of a Atom? What about matter how would that play into the equation of the Milky Way Atom?

Simple answer: No.

The galaxy is made up of a lot of matter that is formed into sphere from small asteroids to teh massive black hole at its center. And atom is much less substantial exsisting mostly a enegry that doesn't even firmly exist as a solid tangable thing.

If you want more details just look up gallactic formation theroies and atomic structure.

Actually the funny thing is that our solar system, and in turn the galaxy, is the model for our concept of atoms. Atoms have not really been proven to have the structure that we are commonly lead to believe. They are portayed in such a way so that we can comprehend them.

Dark matter and dark energy that is composes 96% of space which are not made of visible matter.

Plus there's no black hole in the nucleus of an atom.

Thanks for your responces, My son was asking the question and I kind of botched it for him by making referance to our galaxy rather than our solar system. I think the outcome would be the same though thanks again.

It's could be only seen as a sun having planets swirling around them =
atom having electrons swirling around them.
But others anwered the question allready

Well, the solar system is no longer the modern model of the atom. The planets can't just stay in certain orbits and can only be changed to another orbit with a very precise amount of energy. Electrons can't stay between two levels. This has to do with the solutions of the electron's quantummechanical probability function, which only permits certain solutions. This also bring us to the second point, electrons are now no longer seen as points, but a cloud where the electron probably is.

In conclusion, the solar system is a nice analogy if you want to explain the atom to someone that doesn't know anything about the atom, but when you look deeper into the structure of both the analogy breaks down.
