AI Thread Summary
If the Earth were to suddenly disappear, the gravitational pull on an object thrown into the sky would cease, resulting in its potential energy becoming zero. The formula for potential energy (Mgh) relies on the presence of gravity, which would no longer exist without Earth. This scenario raises questions about the conservation of energy, as the sudden removal of Earth violates established physical laws. The discussion highlights the complexities of energy conservation in hypothetical situations where fundamental forces are altered. Ultimately, the disappearance of Earth challenges our understanding of physics and energy dynamics.

earth disappear!

Suppose an object is thrown onto the sky from the surface of the earth. After it reaches certain height, Earth disappears without disturbing the surrounding or the atmosphere.
what happens to the potential energy of the object.
as there will be no any gravitational pull, eventually, potential energy of the object will be zero. However, my question is what happens to the potential energy (Mgh). how is the total energy going to conserve

What happened to the earth? As soon as you vanished the Earth you violated conservation laws. Why do you expect conseveration laws to be valid for your test object?
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
