in an endless black tube of nothing but temperature variation for more than half an hour? there's not even air in there and the sensation of falling only applies while youre still accelerating at a noticeable rate. after a few minutes you wont feel, see or hear a thing.

If you made the tunnel, allowed time to fill it with air, then jumped in, air resistance would limit your acceleration to terminal velocity. But after passing the center of the Earth, your momentum would be competing against gravity and wind resistance. You'd never make it to China.

Would you actually end up coming out the other side if you fell like this? Wouldn't you just begin and oscillation back and forth, never quite reaching the surface again, losing energy each time, until eventually you're just stuck in the core?

There have actual projects to make gravity powered railway elevators. The earliest rail systems, like a few in England and Wales, used gravity to transport large cargos. So long as both points were at the same True Elevation, counted from the core rather than sea level, you would come to a perfect stop just as you arrive... But have only a half second to grab something, or you will be returned to sender.

@@williamd6621 At the beginning, you have a whole lot of potential energy and no kinetic energy. As you fall, your potential energy is converted to kinetic energy, until you reach the centre and have a whole lot of kinetic energy and no potential energy. Falling out the other side, the reverse occurs - kinetic back to potential. With no air resistance, all that energy would stay in the system, just converting back and forth between the types.

@foobargorch 8 жыл бұрын
+JustJason it's justified because "constant stuff" doesn't change the nature of the curve, a linear function times a constant is still a linear function. Linear transformations can be done at the beginning and the very end to make sure things are in agreement (e.g. the unit system), but don't really matter when it comes to finding a strategy to reason about the equation, in that respect they serve only to distract and potentially introduce calculation errors.

You need to solve fort for the special "Clean Case" to figure out what formulae you are going to use, you then get an answer to help later when you add in the messy RL stuuf, and you can compare to see if you answer for messy life is close to the clean case, or if it is orders of magnitude off. - If your real-stuff answer is way off the clean case, you may need to reassess your assumptions and math.

It is also worth mentioning that, assuming Earth has constant density, it doesn't matters if you are falling through the center of the earth. You can go a little bit sideways, it would be also the same time. Or even completely sideways. Like trying to dig directly from London to Paris. If there is no friction with ground and if you will just jump in the hole, you will also arrive in ~42 minutes

I don't get why we can cancel out everything that's obove us in the "shaved earth" model: the gravitational force depends on how far you're away. That means that if I fall straight into the hole, the part above me attracts me much more than the part opposite the earth pulls me down, because one is much closer than the other -> smaller radius, more attraction (G*m1*m2/r^2). Is my question clear?

Awesome video, thanks! Just so long as no one turns around and says "why haven't we built this yet?!". I've had to explain to someone that this is not pragmatic, and never will be in the conceivable future. We're talking about drilling a hole through the mantle, through the core, through everything that idles at incredible pressure and heat. We and our perceivable future selves cannot deal with that; we can't even dig more than a few km through the crust before our best equipment starts to break down. And our tunnel has to endure the internal forces of the molten core not only squeezing it, but also moving around inside while the continents are moving at the surface (albeit both at a geologic pace, cm per year; but there's no super-ancient society that built tunnels through the earth for us to ride). And the Coriolis effect makes the ride down difficult. And then you need to survive the heat and pressure during the ride, not just the equipment. And.... Okay really there's no point enumerating further. But sometimes people read sci-fi stories and think they're an authority on the subject. So yea it's not realistic. Same with pushing the end of a pole that reaches between planets to produce faster-than-light communication... just no.

Hey, great video, thank you. Maybe you could add some extra info to make a bit more complete: what is the top speed you'd reach, the expected temperatures as you fall, maybe a simple vídeo showing the moviment if you jumped from the equador... Hum, maybe the terminal velocity considering air friction, so as just to show how far from the center you'd get, after crossing the center, in a more real situation. (I'd skip the air density change factor, but that's up to you). Thanks again!

If we were to include air and subsequently include terminal velocity in our maths, you would be unable to reach the other side. You'd reach the centre, then fall so far as to decrease your velocity from its terminal state to zero, at which point you then approach teh centre again. Eventually, you'd run out of momentum and be suspended at that central point, whereupon the intense heat would cook you inside out like a develled egg. Or a large turkey. Or basically any foodstuff that experiences such.
