- You’d need 40 million meters of rope to wrap tightly all the way around the earth 🌏 What if you wanted to raise the rope 1 meter off the ground all the way around - how much extra rope would you need to buy? 🤔
Nice. Once the rope is raised off the ground, how fast does it need to be rotating around the earth in order to stay suspended against the pull of gravity?
You don't need to just let all the 1 meter penguins hold the rope by their head all around the Earth. hahaha
@@carlrodalegrado4104 Yep. The penguins will take over the world and build a giant snow continent covering thr entire earth. That continent will come to be known as Pengea!
@@johnbarron4265 or...or Antarctica 2.0 because we bombed ourselves into a nuclear winter

I have seen this "proof" before (including Wikipedia and other sites that are copying
this "proof"). I believe this flaw has been perpetuated by people because it makes
them look smart, but I believe there is a flaw in your thinking.
BTW: We do know the radius of the Earth (average 3,959 miles). Note that adding C + 6
does not make sense in your equations because it should be converted to an actual unit
of measurement, not just "R". You cannot cancel out the "R" the way you did if you use
real measurements.
If you convert R1 to feet and then calculate r2 = R1 + (height), you will see the
difference. The concept that R is irrelevant to the solution doesn't make any sense.
Instead of trying to cancel out the R values, replace them with "feet" and you will
get a more reasonable answer.
There is no paradox if you do it right. The fact is that the larger the R value, the
more the increase in the size of the belt will affect the height of the new belt above
the old belt. Try it with a basketball and then something else larger.
The problem here is your assumption that R / (R+10) is a constant is incorrect. Note: 2 / (2+10) = 2 / 12 = 0.167. Note: 100 / (100+10) = 100 / 110 = .909. Can you do this? It is not a conundrum, just an assumption that believing that because R / (R+10) seems to be a constant, it is NOT a constant when putting real numbers in there. Also, you have to use real measurements. The usage of 6.28 feet in your video is incorrect. How did you come up with feet if you cancelled out R? Try the entire calculation using feet (convert miles to feet first), then see what you get. Sorry to burst your bubble.
The units come from the amount you want to raise the rope. It's a simple, algebraic expression. 2*pi*R where R=r+1m so the full expression is 2*pi*(r+1) the 2*pi distributes. and to see how much more we need we subtract off the original 2*pi*r
