He proved a few of these wrong. The book falling through the earth one for example, pretty sure he figured it out in a video and it's more like 13 minutes.

I think it's more saying that if there was a constant force of gravity pulling that book down, it would take that long. Obviously it's impossible for a book to go straight through. It would just stop in the middle (assuming it's not burned up).

Actually it would smash into the sides and get destroyed that way before it burnt up. Due to the earth spinning while the book is falling straight down.

For anyone wondering. His youtube channel is call Vsauce. Its a science channel that hits on a great topics and very fun to watch.

"2 to 9 pounds of our body is bacteria"

"we are more bacteria than human!"

Bacteria don't weigh that much because of their size in comparison to a body cell, I believe.

As I understand about 90% of the cells in and on our body are bacteria, and about 10% of our mass is from bacteria.

Bacterial cells are much much smaller than the cells in your body. OP's trying to say that we have more bacterial cells than we do of our own.

in that case we have more cells being bacteria, but most of us is still human flesh, seeing is it has the most mass

If you drop a book (or anything else) down a hole through the earth, it tkaes roughly 42 minutes to pop out the other side of earth. This amount of time is the same, no matter what direction the object is falling

acctully if you drop an object in a hole that goes straight through the earth it would never reach the other side, or even the middle. The combination of earth's rotaion and gravity confuses the hell out of the object so it goes "**** it, I'm just gunna chill here on this wall."

And the 45 minutes assumes that the acceleration would be constant, but since gravity is an inverse-square law, the acceleration itself would accelerate and it would fall even faster, likely to burn up as an asteroid does in the atmosphere. It wouldn't even last long enough to chill on the wall.

I'm guessing it would burn up do the fact that most of the earth is liquid metal and rock. But if you could somehow build a walled, climate controlled tunnel through the earth - as the book fell, it's relationship to the mass of the earth around it would change very rapidly. By the time it reached the center, you would have gravity pulling it in literally every direction. Needless to say, the point I'm making is that at some point, the gravity of the rest of the earth would start decelerating it as it passed through.

No. That is not how physics works. Acceleration due to gravity increases as you get closer to the center of an object (i.e. the acceleration due to gravity halfway between the surface and the core would about 90 m/s^2, instead of 9.8 m/s^2, meaning that the acceleration increases as you get closer to the center of gravity. Fact.) The book would be traveling so fast that it would burn up regardless of the temperature of the mantel, because it probably wouldn't even make it there anyway, meaning that any additional gravitational forces the book has already passed, and are acting against it, are negligible.

Wikipedia Disagrees.

Twice.

And so do these redditors:

www.reddit.com/r/askscience/comments/15rey3/if_you_were_inside_a_giant_hollow_metal_planet/

The point I'm making is that the earth is not a point mass, like you're treating it. It's an amalgam of separate matters creating non-uniform gravity. That's why they can use gravity meters to search for oil deposits - since it's less dense than rock, it lowers the gravity over it. They mention that in the article I'm about to post offhandedly in the first paragraph. It's an article about seismological surveys, but the point is clear.

You have come to a classic contradiction, haven't you? Initially, you said an object would decelerate, suggesting a net gravitational force, now you incorrectly call on theories that assume a HOLLOW Earth, which is not being debated, which states that there would be NO net gravity inside and disproves your previous incorrect statement. The information in your sources is correct, you just don't know how to apply it. For instance, "A corollary is that inside a solid sphere of constant density the gravitational force varies linearly with distance from the centre." (A difference in alloy densities, like the irrelevant point you made, would only allow for a negligible variation in acceleration.) I don't care much to continue giving you a free education, so take this as you like. Good bye.

I was in initially wrong, that's true. But so were you. The rest of the sentence you quoted was "becoming zero by symmetry at the centre of mass." - which is the opposite of what you said in your initial post. The acceleration due to gravity half way to the center of the earth would thus be half of the acceleration on the surface (4.9m/s^2), and not related by the inverse square law.

Through reasoned debate and a little research, we've both been proven wrong and come to a more correct place of understanding. Don't turn your nose up at that, it makes you seem petty and small.

i just realized with the one trillion seconds remark. so if america save $1 every second it wouldnt pay off our debt in 32,000 years? even if we saved 10000 a second how long would it take to pay off 14 trillion dollars of debt??? oh yeah and. congrats.
