Oh dear, the things we come up with to pass the time when there is no Camino ............
Hahei is indeed very very nice!I would not mind living in Hahei, not at all!
All New Zealand is AMAZING, but in my memory there is always a special place for Wanaka, Orepuki, Nelson and Hahei, I just LOVED those places, want to go back!!!!Hahei is indeed very very nice!
I'd also be all wet, David. I'd find myself 245km WSW of the nearest solid ground, Saint Paul Island, a tiny remnant of a volcanic crater in the middle of the Indian Ocean which Wikipedia tells me is all of 6.2 sq km in area. Actually, now that I think about it, I think may have talked to someone on Saint Paul Island many years ago when I was an active ham radio enthusiast. It's a small world, after all.Hi - this is a fun app - shows you where you would surface if you dug a tunnel through the planet - Santiago de Compostela would come up in New Zealand, West coast/Canterbury border.
I would drown, coming up in the Pacific from Oxford UK!

I'm swimming, too. It looks like I'm about halfway between Perth and the Island of Grande Terre southwest of Australia.Hi - this is a fun app - shows you where you would surface if you dug a tunnel through the planet - Santiago de Compostela would come up in New Zealand, West coast/Canterbury border.

An "interesting" fact is that it would take about 40 minutes to fall through the tube and come out the other side, assuming no air resistance. Almost as interesting is that it would take about 40 minutes to fall through any tunnel dug in a straight line between any two points on the Earth's surface, assuming no air resistance or friction with the sides of the tunnel.
Another peculiar notion, seemingly held by many Americans, is that if they were to dig straight down from anywhere in the USA, they would come out in China, whereas there is no point in the USA that is opposite to any point in China.
Isn’t the inside of the earth supposed to be molten rock? Steps would have to be taken to skirt that; that would increase the distance and the time required. No?
Yes, gravity diminishes as you approach the centre of the Earth, zero at the centre, to be exact. But gravity diminishing does not slow your speed, it only slows the rate of acceleration. By the time you get to the centre (20 minutes or so) you have been accelerating for 20 minutes, so you are going very fast. You then start to slow down (due to gravity pulling you back), and your speed will be zero as you come out the other side. It is the same principle as a pendulum. There is no net force acting on the pendulum as it passes through the centre of its arc.Would there not be a diminishing of gravity as the core was approached, slowing the speed of travel?
so glad that the US and China are not opposite each other, if they were there would already be freight train lines transferring goods!
It's very much a theoretical calculation. Nobody (in their right mind) dreams of making a tunnel through the centre of the Earth. But it's a bit surprising that the time would be the same for a (theoretical) tunnel going in a straight line from London to New York, or from Moscow to Cape Town, avoiding the centre of the Earth, and assuming no friction or air resistance.Isn’t the inside of the earth supposed to be molten rock?

I think the idea is that the tunnel goes right through it but is, somehow, perhaps through advanced technology, shielded from it by heat-proof walls.Isn’t the inside of the earth supposed to be molten rock?

I was thinking about that. I suspect the idea is that, from London to New York you are not going straight "down" (the direction that gravity is pulling) but just a bit down with a lot of lateral movement. So that might slow down your acceleration and it may all even out in the end.It's very much a theoretical calculation.

Hahei is indeed very nice!My town, Durcal, would come up in a place with a beautiful name: "Bay of Plenty". I would not mind living in Hahei, not at all!
