Which matter doesn't interact with observable electromagnetic radiation?

LionQueenT0727, it is there in the equations but they cannot physically detect it yet... same was true for the atom and the quark... so maybe one of these days it will show up and be just as natural to us.

Sounds similar to an explanation of the dark side of the Force.

Thanks, Neil deGrasse Tyler! I just love astrophysics!

95% universe is dark matter, which isn't even discovered yet

it is outer space I find what is going on. in space is just great ok

VividPotion6704, Don't forget that the Higgs Boson particle eluded scientists for decades. They were positive that it was there and had the formulas for quite some time. As with many theories, it took a while for technology to catch up to the idea.

LionQueenT0727, Love this, btw. Very clever.
