Is that William Shatner over-acting again.

That is Shatner playing a deranged Captain Garth at the penal colony, where Garth is using his shape-shifter ability to look like Kirk and flipping out when Spock calls his bluff on asking for a chess move passcode as a way to transport back to the ship.

Basically saying that chemical fuel is not exactly optimal for deep space travel. For escaping earth’s gravity well it is ideal, since high thrust is required rather than specific impulse. Nuclear propulsion becomes the ideal thing after that, generally having low thrust but high specific impulse. I wish I had saved all those Scientific American magazines I used to buy. There were some interesting articles.

This unfortunate fate will inevitably confront us in less than a billion years, when the sun will heat up enough to boil all water off the face of the Earth. With proper planning we could relocate to a new home by then.

How friggin' profound...

Hmmm...The PC crowd has missed an important opportunity, for them, to protest these poor size-disadvantaged stars being referred to with such hurtful language...

”A civilization in the habitable zone of a dwarf star like Proxima Centauri might find it hard to get into interstellar space with conventional rockets”

Good. The last thing we need is a bunch of aliens from the Proxima Centauri system showing up on our doorstep seeking welfare and demanding that we celebrate their culture.

i especially liked the advice to properly plan our escape from earth within the next billion years. I would suggest no planning of any kind until we are within, say, 5000 years of the need to do so.

If we’re around in ANY corporeal capacity in a billion years it’ll be possible to just move the earth further out...

Exactly why we need to get there first and we institute quotas so that Proxima’s can be documented and thus legal aliens. We should only allow Proxima’s that have skillsets that complement those on Earth.

Uh-uh. We’re going to need every one of those billion years to haul seven billion of us off to Proxima Centauri b! Can’t do it in 5,000. And what about the poor animals? Proxima b is going to be a pretty bleak place without BBQ’d stuff.

No. It's William Shatner doing exactly what the director told him to do.

In a billion years, if we are still around, I’d say we will have mastered interdimential travel and can go anywhere in the universe in an instant.
We’ll probably be creating stars at that point. So we’ll have a new one in waiting when the old one is ready to retire or we’ll just give it a quick charge to last another 5 billion years.

Yep, it is the “4000-7000 angstrom privilege” issue Earth has been dealing with for 4 billion years or so. Man, those complaints get old after a while!
