Well, as interesting as it was, and I enjoyed it, for the general viewer it was just a Doomsday fear-mongering exercise of doom and gloom, and we're all going to die AAGGHH!!!
But I did learn something I didn't know. M31 Andromeda Galaxy has two central cores!
Proof that is has collided with, and absorbed, another galaxy.
Thanks for the heads-up for this Show Martin
