Interesting thought. I imagine if there is a way to do it, we would have to look inside of a photon to find it.

Astronomy is the one science where most of what is learned is by observation and not hands on. (We can actually touch a start like a Geologist can pick up a rock.) Most of this data comes from the light we receive. This light, in the form of a spectrum, can tell us what matter the photons were reflected off. The red or blue shift of the photons can tells us about how an object is moving,

But what if we could turn Astronomy into a hands on science by ‘grasping’ the photons and studying them as an objects. What could they teach us?
