Hello Fellow Earthlings. Normally we enforce a rule that all posts in r/earth need to be Earth-related, but in this weekly thread we relax that and open up for any off-topic discussion you'd like to have with your fellow Earthlings.

Just keep in mind that the other subreddit rules - including rules 2, 3 & 4 will still apply here!

I’ve never really thought how big the earth actually is, but this sure does tell me.

Burning steel wool

I need help, I am attending a “sustainability “ fashion show where they want to burn steel wool as the element of fire. I’m not a science person but I know some basic physics and chemistry. I know when metals are burned they release a gas or solid of some kinds and most of the time it’s toxic xis to humans I also know nano particles of these can travel in the air as well. Originally they were goin to use 300 bricks to build a fire place but I started looking things up and it seems like they were going to poison the whole city. I’m concerned because these are a bunch of art students that know nothing about science, they are also not locals so they don’t care about this community or what the long term effects may be to the air of this community, I just want help figuring out if them burning it at all is safe, they now currently want to do it in a vase but it will be open and still exposed to the air, we also live in a high humidity environment which I read can make it combust like a bomb I don’t know much but I would like help, so if this is going to poison my community I need facts to build a case and google isn’t helping me

If there was a hole going straight through Earth, one side to the other, and you dropped a quarter through the hole, assuming there is nothing in the way of the quarter, when it comes out the other side would it just shoot into space? Would it change gravity somehow and just fall onto the ground?

So I have read and watched multiple videos about this question. One said that if we all got shoulder to shoulder we would only cover the size of LA. Then we all jumped, we would only move so small that it’s the size of an atom. Then the following said if we jumped in china we would throw earth off its “axis”. Someone please help me understand how this works. Thanks!

Earth provides us with life, and now is the time to take action. Let’s unite and start to embrace our planet earth for a better future!

Maybe you can help me. How come I can see the moon during the day in the US? If Asia is using it at night?
