I just came to point out the x-rays or whatever are not 15,000 years old. They are new. Time stops when traveling at light speed, so to the x-rays themselves they have just left when they arrived.

From the perspective of the EM radiation traveling at C, yes it would be instant.

They were still produced 15,000 years ago and are therefore 15,000 years old
