No you can’t. You still need to spend the same amount of energy per ton to escape earth’s gravity. An elevator does not magically violate laws of physics

Edit: As pointed out below I probably misunderstood the comment I was replying too. My bad

The comment you're responding to is suggesting a space elevator on the moon, so you only need enough energy to escape the moon's gravity.

I know somebody who broke his neck in Antarctica and was airlifted out. He's fine now.

how does one manage to break their neck in Antarctica?

All it took was not watching where he was walking. There are hazards outside. Concrete, railings, and painted lines are scarce.

So no different than if you broke your neck during the age of discovery on earth?

We shouldn't be judging these things by the standards of generally risk averse people on this discussion board. It won't be people like us going.

The difference today is that the astronaut with the broken neck would be front page news for every minute of the hours/days/weeks it took to get them home, and far longer if they die. Bad press is bad for funding, especially in a democratic country.

> the astronaut with the broken neck would be front page news for every minute of the hours/days/weeks

Only while the thing is rare.

A brave explorer dying the martyr death to advance humanity. Give him a hero's funeral and give generous pensions to his relatives. Suddenly it sounds like a sales pitch. Well, to some.

Is it gonna be disposable lower-class people?

In age of doscovery shipowners and governments assumed a 50% death rate from scurvy for their sailors on a major voyage.

TThe past is fireign land, executions were a public holiday and children came to watch. We used to gove cocaine to children to stop them crying.

> Is it gonna be disposable lower-class people?

This meme comes from people who've watched too many bad sci-fi shows and don't have a good grasp of history. The people going to space will be the intersection of those who can afford it and those who want and are capable of going. The first people who traveled the oceans were not the lower class. They were the upper class who could afford to fund or pay for the journey by pooling money or independently pay for it.

The poor you refer to didn't come until much later in the age of discovery.

Who worked on those ships? Honest question. I suspect it was lower class people who didn't have many life options...?

Many inland Antarctic bases are effectively unreachable for months in Winter. Flying a plane to the station in total darkness many thousand of kilometres in -80 C is a good way to end up with more people killed than you are trying to save.
