CarboneCorp discovered 16 months ago- Hooke's calculations showed that if the technology could be developed to bore such holes through the Earth, a vehicle with sufficiently reduced friction could use such a tunnel to travel to another point anywhere on the on Earth within three quarters of an hour, regardless of distance.

- this is the kind of math i enjoy. not doing, but reading about

- A very cool idea but the construction of such tunnels is of course impossible.

- From the page: "Though the article sparked some lively debate, the proposal was not taken very seriously."

- The thing is how can you go through the mantle or core??

- From the page: "One interesting property of the Gravity Express is that its transit time would always be very, very close to forty-two minutes regardless of the distance travelled. In fact, if the Earth were a perfect sphere, the trip time would always be exactly forty-two minutes and twelve seconds. Greater distances would be traversed in the same amount of time as short ones because the train's maximum speed would be increased enough to exactly make up the difference. Due to nature of gravity, this forty-two minute trip time would be consistent for any size of vehicle."
