Wake me up 25,999 years from now to be concerned.
What has ME concerned are the remarks that the galaxy center is 26,000 years away.... and they are talking about xrays originating 300 years ago???
Ummm xrays are the same as light or other radio frequency energy, thus travel at the speed of light... Which means, we didn’t detect it YET if it just started “300 years” ago.
Someone has their head firmly planted somewhere other than in the stars, or in astrophysics (Astrophysics doesn’t change the math, sorry)
