damninteresting.com — In the 17th century, Robert Hooke showed that if the technology could be developed to bore deep 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 45 minutes, regardless of distance. Even more amazingly, the vehicle would require negligible fuel.

@jdavidthe article itself mentions towards the end that the "standard trip times" will be different on heavenly bodies with different densities. what he/she/they forgot mention was that the times would also be different for same density but different radius.

This might not be possible across really huge distances because of the pressure and engineering required to go through the center of the earth... but what about across a continent, like from NY to LA?

that doesn't make much sense to me man

"what i am concerned about is how would you expel the liquid waste from your body in zero-G and how would you move around in the train to get to the restroom? those are not technological hurdles. but is it practical to train so many people to function properly in zero-G?"Heh, I don't think you'll have to worry about that, just issue Depends to everyone. When they look out the window and see molten lava whizzing by at 7400 mph, people will be expelling liquid waste with abandon anyway.

My thought exactly.Imagine being stuck in the centre of the earth.

alky, Actually you should take the physics class -- you experience 1G of force but not acceleration. You only experience the acceleration once the 1G of force the ground is exerting against you is gone. You've mixed up force and acceleration.
