Science Buddies: "Ask an Expert"

Is Matter is a condensed form of space, and dark matter what we refer to as the fabric of space( a non condensed form of matter) ?, from my perspective the universe is not expanding but collapsing, planets, solar systems and galaxies are continuously falling into a pit created by condensed space ( perceived as gravity )

What would be considered an evidence that would disprove this ?

The Science Buddies Ask the Expert forums are for students in grades K-12 who are doing science projects. There are other forums on the internet where your questions would be more appropriate.
Thank you.

I like all the friendly comments, I am very happy.
