I thought X-rays and visibile light both traveled at the same speed. Why would the X-rays arrive first?They were emitted first. I don't know why the visibile light was emitted later. I'm not an astrophysicist.

I agree, we should make the ozone layer very thick.

Yeah, I wonder about those “dark spots” in space, the ones that light doesn’t shine through and which do not seem to have enough mass (thus weak gravity) to bend light around them? Could be Dyson constructs, yes?

They would be very old, constructed in the earliest eons of the universe. If the stars inside had supernovaed, they would of course shredded.
