Explain

Quarks and gluons, the strong and weak
Building blocks surrounded by emptyness
Matter constructs all that we seek
Be it light of dark more or less
Or just a form of energy conserved
At least while it's at rest
Is it a wave or particle or both at once
A double slit will help to test
The ether was and then wasn't
And then came back relatively sudden
Really you only had to look for it
Just let it pop in and out of the oven
Time to take a string and roll it on up
Eleven dimensions later your head is stuffed
