How long would it take to fall through the Earth to the other side?
In work published in the American Journal of Physics, Alexander Klotz found that the trip to the other side of the Earth should take about 38 minutes.
Can you fall all the way through the Earth?
The simple answer is, theoretically, yes. First, let us ignore friction, the rotation of the earth, and other complications, and focus on the case of a hole or tunnel entering the earth at one point, going straight through its center, and coming back to the surface at the opposite side of the planet.
How far is it through the Earth?
The simple quick answer is 3,958.8 miles – the mean radius of the Earth in miles. In other words, if you dug a tunnel straight down, you’d reach the center of the Earth after going 3,958.8 miles, and then you’d need to go another 3,958.8 miles to reach the opposite side of the planet.
How long does it take to dig to the center of the Earth?
A scenario often presented to introductory physics classes is that of a “gravity tunnel” — a tube drilled from one side of the Earth to the other through the planet’s center. The answer taught for nearly a half-century for how long a fall through such a hole would take was about 42 minutes and 12 seconds.
What would happen if you jumped through a hole in the Earth?
Without air, there would be no air resistance. You would therefore accelerate to incredible speeds as you fall, reaching a maximum speed on the order of tens of thousands of kilometers per hour . You reach earth’s center in a matter of minutes or hours instead of weeks.
Can you fall off the moon?
Although you can jump very high on the moon, you’ll be happy to know that there’s no need to worry about jumping all the way off into space. In fact, you’d need to be going very fast – more than 2 kilometres per second – to escape from the moon’s surface.
How long does it take to leave Earth?
“If you think about it, we’re accelerating a 4-1/2 million pound system from zero miles per hour to its orbital velocity of 17,500 miles per hour in those 8-1/2 minutes. So it’s a heck of a ride for the astronauts,” explained Mike Leinbach, a launch director at NASA.
What if the earth started spinning backwards?
If the Earth suddenly started spinning in the opposite direction, everything not fixed to the ground would be launched at 3200 km/hr eastward. This would happen because everything will still be rotating due to inertia towards the east, while the ground suddenly moves towards the west.

What does the Moon smell like?
After walking on the Moon astronauts hopped back into their lunar lander, bringing Moon dust with them. They were surprised, and perplexed, to find that it smelled like spent gunpowder.
What is deep under the Earth?
The inner core It’s located some 6,400 to 5,180 kilometers (4,000 to 3,220 miles) beneath Earth’s surface. Extremely dense, it’s made mostly of iron and nickel.
