Rede- Is it not the point that it would be necessary to have invented warp drive (or something similar) if the anticipated mass extinctions (for whatever reason) happen? Certainly mass extinction cannot be ruled out in the future, or even in the present the way things are going! It seems to be a default position for uppity species.

Perhaps that is the reason we are starting up the space programme again. Maybe?

In what seems to be increasingly just a gesture I am arranging for the replacement of my power-guzzling light bulbs (free!!!) but I feel like I am bailing out the sea water on the Titanic with an egg-spoon!

PS I did try to start up the video without success so I am not commenting on that.
