The answer to the question of falling through a hole straight through the center of the Earth is a bit more complicated than described. Yes peak velocity is reached at the center of the Earth. But peak acceleration of 32ft/sec^2 is reached immediately upon jumping in. Although you accelerate the rate of acceleration continuously decreases until it becomes zero at the center. Then acceleration begins to increase again until reaching 32ft/sec^2 but importantly the direction of this acceleration is in the opposite direction such that your velocity reaches zero upon reaching the other side of the hole. As you fall initially the entire gravity of earth is a sphere below you...but as you fall into the hole more and more earth is now pulling from above you and less and less from below you....hence these forces are opposed and gradually reduce the acceleration from its initial maximum to zero acceleration at the center where you reach peak velocity. : )

[@stevenmcgrew869]

How about the fact that gravity comes from the mass of the earth, and the hole is an absence of mass? Wouldn’t a person be drawn towards the wall of the hole at some point, and then friction would halt their movement at some point, so they would end up resting against the wall of the hole somewhere near the center of the earth?

[@stevenmcgrew869]

Actually, now that I think about more, the gravity would be equal all the way around the hole, so it wouldn’t pull a person to one side of the wall of the hole.

[@RyanSnead]

​@@stevenmcgrew869 I kept wondering from the time they complemented the kid on removing the heat from the core as an assumption how air resistance and friction would affect the jumper and Dr. Tyson's explanation. I believe the given explanation would assume a vacuum in the hole, decompression protection for the jumper, and a recirculating breathing apparatus for the jumper. (Did I miss any other assumptions?)

Disco didn't truly die. It just lost mainstream appeal, and then mutated and diversified into other genres for a bit. The birth of House music in Chicago for example. The bands of the 80s used a lot of production and tech developed during the end-era of disco and made it into its own thing. Pop integrated a lot of synthy sounds and heavy production. Its very similar to how various techno music bubbled up into pop into the 2000s. Dub-step, Trap, etc. Retro-synth styles and cross-breeding thanks to groups like Daft Punk and various producers.

[@outdoorsy01]

Would the Earth's rotation affect things? In other words, after 5 minutes of falling, you hit the side of the hole. Or would your rotational momentum like that of an apple thrown inside of a car travel the same speed?

[@Sammasambuddha]

Good question. I'm going with matching rotational speed. Mainly because Neil mentioned the orbiting Space Station how'd you meet/see it on each side of the planet perfectly timed because you'd both be falling. So, the fall through the center of the planet is an orbit too.

Question: Referring to the expansion of the universe, it's it possible the expansion is caused by particles, photons, quarks, and many other forms of what make the universe? Similar to Hawking radiation that evaporates a blackhole, the shredded energies of any mass as it decays become space pressing it in every direction. So take a rubiks cube, the outer sides of stickers press on nothing. The inside stickers press on the inner rim of adjoining cubes. The center sticker presses out on the rim of all its sides. The push from the center cube adds to the force of the outer cubes push further expanding them at a more rapid pace then if the center pushed alone. Granted momentum and gravity also play their role, this is just a brief idea.

[@TheUmbroDragon]

If I had to guess on why their couldn't be absolute stillness. I'd say it would have to do something with the fact that time is always a constant. If something was absolutely still, it would just mean time has stopped. However , that being said. We could probably get really , really close to almost no movement. Which would appear to us like it isn't moving , but in reality. That object is moving so slow , it would probably exist until the end of time. Or rather the end of the universe, because I'm not certain time would end even after that.

Hey Dr. Tyson, I'm a huge fan of your work and love how Chuck and you digest subjects together. I have a weird question. When I imagine ripples in spacetime sent out by two holes spinning around eachother until they merge, I imagine it to be kind of like two constant soundwaves in water with their origins circling eachother until they merge. Does that make sense? I guess my question is, if whales like orcas and beluga would know and think about spacetime, could they have a better understanding because of their echolocation and different understanding of gravity? And could we soon communicate ideas with them in the future? Greetings from Germany.

[@johndoyle2347]

At the particle level, there is no absolute zero temperature - there is still fluctuation going on as you say. This is because the particles, governed by the stability of Euler's Identity (recursive form, solved for the imaginary number), have singularities of either a cusp (dark matter) or cylindrical nature (baryonic matter) as shown in differential calculus, where there are 5 cases of functions that are continuous, yet not differentiable. The cylindrically shaped singularity corresponds to jump discontinuities. There is a bit more on how dark matter cusp singularities are paired up and how there is a maximum and minimum point to the cylindrically/hypodermic needle shaped baryonic matter singularity. But, this is the heart of it.

[@NeverDoneEver]

I once read a short story about aliens who used a cosmic string or something to essentially core the Earth like an apple, spun the string around in the hole really quickly to keep it open, then tossed a human astronaut (in a very good spacesuit) into the hole to watch him bounce back and forth. Wish I could remember the name of the story.

[@Duane_Day]

There is a difference in perceived strength on Mars versus Earth due to the difference in gravity. While you’re not actually stronger on Mars, the reduced gravity makes it appear as though you are. For example, if Dr. Nice can deadlift 175 pounds on Earth but cannot lift a 200-pound weight above his head, he might be able to lift that same 200-pound weight on Mars. This happens because the gravitational pull on Mars is only about 38% of Earth's, making the weight effectively lighter. So, while Dr. Nice’s muscle strength hasn't increased, the lower gravity on Mars allows him to perform feats that would be impossible on Earth. Thus, while he isn’t actually stronger, the lower gravitational force gives the appearance of greater strength, enabling him to lift weights that he couldn’t lift on Earth. Alternatively, I’m wrong !! can somebody weigh in?

[@ThrupenceBarkley]

This was already over explained in the video. The gravity on Mars is weaker so things weigh less. That's enough for most people to 100% understand it.

@@priidik12345 Potential energy depends on mass, gravity, and height (PE = mgh).

[@EricSchultz-zs8hz]

About jumping into a tube that goes through the Earth, I thought of one thing you could do to get a little more momentum so that you can grab the edge on the other side, so that you don't fall back in. You could stand on a tall ladder or platform above the tube before jumping in, so that you could add on 6 or 8 feet of falling momentum before actually going below the surface of the Earth. That way, when you get to the other side, you would have just enough momentum to go a little above the surface on the other side, and then reach the edge before falling back in. Of course, if you were in the middle of a 10 foot wide tube, you wouldn't be able to reach the edge. You wouldn't want the tube to be too narrow, either, or else if you touched the edge while falling, you would have a fatal amount of friction.

[@kg4wwn]

A 747, which is significantly bigger than Swift's plane, produces approximately 105 lbs of CO2 per mile. It has a cruising speed of 570 MPH. So one hour would produce 59,850 lbs of CO2. If the plane were running 24/7 for a year it would produce 524,286,000lbs of CO2. Converting units, that's ~237812 metric tons. The world's annual output of CO2 is 37.15 billon metric tons. So if Swift upgraded to a 747, and She decided to fly 24/7 every single day of the year, her contribution to our CO2 emissions would be 0.00000401% of the world's total emissions. Her contribution to the carbon footprint is statistically 0. EDIT: Not sure if the person I was responding to blocked me because they don't like facts, or if they realized they were wrong and removed their comment, but I can no longer see it. I was replying to someone who thought that Swift was a major source of carbon emissions.

I thought that the deceleration rate decreases as some of the globe of the Earth's mass is now "above you" as you fall. And I guess we have removed the air so that there is no 'terminal velocity' effect posed by that. This is like (similar to) a pendulum swinging. The initial 'fall rate' as the bob is released is higher than its velocity through the bottom of the swing arc and then back up the other side of the swing arc it slows at a constantly different rate as well until the peak of that swing. but one supposes that the string poses a factor here. Is the pull of Gravity atop Everest different than in Death Valley or some deep hole we have carved out? If it does differ, then it also differs as the fall takes place.

[@vortexkeeper1902]

The whole thru the center of the earth sounds like the best water slide ever.

[@jasonjohnson9072]

I imagined if you fell to the centre of the earth that as you approached the centre the accelation would reduce and you’d just stop in the centre. I had it in my head that as you approached the centre the gravity of all the surrounding material would cancel each other out.

[@kevinafrank104]

OK, Because at the center all directions are up, there cannot be gravity, Ergo, there has to be a point at which the gravity starts to decrease before reaching center. The basis to this concept is because most of the earth’s mass is above you relative to the center of the Earth therefore pulling you in that direction.

[@jwmmitch]

I'm super curious about the round trip through the Earth (or any planet) taking the same time as an orbit. The two things that seem like they would make the times different are that as you pass through the Earth the effects of gravity would change every foot you travel as more and more Earth is above you the less the acceleration would be. And then also the object in orbit has a larger diameter, but I realize that may not make a difference.

It seems to me that the rotation of the earth at the surface is way faster than approaching the center, so you will hit the side and then bounce and hit the sides over and over, unless you have air resistance. So either way you need it. So you will reach terminal velocity of 200 km/h until the center of the earth if you are able to vector your direction properly to avoid bouncing off the sides, then you will only reach a small % of going "up" the other side, then you will slow down and converge on "bouncing" back and forth "up and down" through the center of the earth until you reach a stop. So not very much fun.

What matters more to gravity, density or mass? What would attract more particles in microgravity? Compare 1 gram of various elements measured at sea level on earth and in microgravity with and without spinning them. Does the displacement of the less dense element offset their relative gravity by having more interaction within the confined environment, or does the denser material attract more material. Repeat the experiment using elements of the same machined dimension 1cm. What is more important the size of gravity creator or its composition? Does the speed of rotation affect this?

Relative to the CMB we can actually be absolutely still in the universe. However at that point we have less time dilation than we have here on Earth so even then there's more motion in the in a body that is still then a body that's moving. It's only like 0.00001% faster.

16:28 Not just to the edge, unless you started at the shoreline, at sea level, in Wales. You’ll emerge from the Pacific Ocean and rise to the elevation that you started from in Wales.

I think for the mars question you were supposed to go through the superman powers... ticking them off one by one... will you be stronger, faster, jump higher, get xray vison, better hearing, bullet proof...
