As the title says. I'm actually thinking about this hard with my friends because everything that's produced on Earth stays on Earth so it doesn't change size, but what if it's not from Earth but it stays on Earth?
Yeah, that checks out. It is an interesting concepts that can peak student's curiosity, but to early to really get into quantum mechanics. So for people that don't further pursue an interest in physics, that's often the last impression they are left with.
I had the fortune to have a physics professor as a dad. I carried a laminated double sided periodic table since elementary school. We didn't even have chemistry of physics until secondary school ....
