1) Do this on the moon. I always thought a "jump through the moon" theme park would be awesome.
2) Why calculate the weight of the traveler and suit? It doesn't matter in a vacuum.
3) You would experience weightlessness for the entire trip, not just at the center of the earth.

Thanks for making a fun video!

[diemme]

actually, weightlessness is felt during the *entire* fall ! (if and when - like in the video's example - the air resistance is zero and the terminal velocity is only due to gravitation: those 28.000 or so km/h) and not only at the earth's center. But ok, we understand that you meant that even something *at* *rest* at the center of the planet would experience weightlessness...

[michaelquigley]

As a fan of physics I have contemplated this in the past. I have to tell you that during your video I was waiting patiently to see the graphic of our adventurer falling through the Earth non-stop and popping out each end of the tunnel. I laughed and laughed and thoroughly enjoyed this clip. Great job.

[EmilyTienne]

Assuming there is air in the tunnel, there would have to be friction as well. The friction would prevent the object from falling all the way through to the other side. Each swing in the opposite direction would become progressively shorter until the object would come to a dead stop at the center.

[DebunkedOfficial]

Did anyone spot the Wilhelm Screams?! 😱

[ruirodtube]

You’d feel weightlessness all the way, not only at the centre of the earth. Like astronauts do when flying a « zero-g » dive.

[ALDZK]

This was one of the biggest questions ive had, glad you made an in-depth video about it

[volkeru]

7:45: What has the mass to do with the velocity in a vacuum? References to Giovanni Battista Benedetti (1530-1590), Galileo Galilei (1564-1642) and Robert Boyle (1627-1691).

That one would feel weightless all the time has already been mentioned in another comment, however the center would be a place where there is no acceleration and thus, after stopping somehow, one could float there in weightlessness.

[inshort]

I've always wondered this! Thanks!

[rubycelica]

what a great video that is! i enjoyed watching every minute of it, thank you for producing such a gem!

[Quickened]

Your research and presentation are always top notch! Your personality makes learning fun... Thanks for your hard work!

[MrHarald]

Guys! As you are falling you always experience weightlessness. Not only at the center of the earth. Also, your mass does have no effect on your rate of acceleration.

[biblomatic]

I was waiting for weeks for your new content.
Love the host
Love the facts
Keep it up

[rogerjrusa]

I LOL’d at the end especially. So entertaining and informative. Thanks for this gem.

[RobertR]

Just discovered your channel. Love your delivery, graphics, and analysis. Well done!

[themaskedcrusader]

interesting fact: a round-trip through the center of the earth takes exactly the same time as an orbit around the earth at the same altitude. Neil deGrasse Tyson mentioned this in one of his interviews. I can't remember who he said did the calculations though.

[jeffchabotte]

The problem is also that your starting point needs to be slightly further away from the core. Imagine your antipodal point is higher than your starting point, so you come up about 3 ft short of exiting the tunnel.

Also, if you launch above the vacuum seal, why not just have it close begins you?

[Vicious]

Debunked's videos are truly a gem
I'm glad to have found this channel full of scientific explanations with a little bit of sass
Entertaining like nothing else, hope you can always keep going!

[moosefactory]

I LOVE videos like this. I have thought about this very same theoretical scenario. I have another one, if there was a massive size planet, one as big as a galaxy cluster and you had a hole dug through the center of it, how close could you approach the speed of light falling through it. What would the speed graph look like. At first is would be going up exponentially but at what point would the rate of descent start to slow down as it starts approaching the speed of light?

[MeetRayka]

You answered the question that i thought no one had except me in my childhood
