Can We Use JWST as a Direct Dark Matter Detector?
How do we actually detect dark matter? Matter that doesn’t give out light, doesn’t reflect light, doesn’t absorb light: nothing.
The only reason we know its there and have so much evidence for its existence is because of our observations with telescopes when we see its gravitational pull and effect on other objects in space.
But if we want to physically detect some dark matter and say this thing here is dark matter, and this is what it’s actually made of, and this is its size and mass, how we do we do that when all our “detectors” use light to know something is there?
Well what about using the James Webb Space Telescope?
What if instead of using it as a telescope, we could use it as direct detector of dark matter...
