Remember, neutrinos don't interact with matter so the Earth is invisible to the tiny particles.

But since X-rays have a different wavelength (and frequency) they interact with matter differently than visible light.

It determines the ultimate fate of the entire universe, yet it doesn't interact with matter in any measurable way.

Although radio and visible light are both electromagnetic waves, there is one thing that is very different-theway that they interact with matter.

But these extremely light particles hardly ever interact with matter, and hence they pass through us without effect, at a rate of billions each second.
