it's all very well physicists to study very small things and very big things but when they start saying things like gravity isnt real except for your mum I start to feel a twinge of skepticism coming in

@falcennial I think there is a difference between not being real and not being relevant.

Quantum mechanical effects for example are only "real" at the quantum level.. that is to say of course they still exist at the large scale but they are such a small marginal aspect of it that it would effectively had no meaningful effect. We can model large objects using QM but the effetive frequency of the object would be so large that the wavelength would be insiginificantly small.

Same is true of gravity but in reverse. Its like caring about an ant on a whales back :)

@freemo I didnt understand this I think because you explained it to me like I am 39. i invite you to reduce the value to 5 and try me again.

but if that doesn't work, we're looking at fractions I'm afraid.

@falcennial You cant see the waves on the ocean from space. But they are still there. That just only matter if you zoom in.
