What would you do if you had the Philosopher Stone?

obviously;The Philosopher’s Stone is not just a spiritual metaphor but an actual substance that can transmute lead or mercury into gold. The Stone is a product of Alchemy. Unlike chemistry, which only deals with physical matter and energy, Alchemy makes use of etheric and astral energies to reconfigure matter at the quantum level. Alchemy is to chemistry what a cube is to the square; it is a superset of chemistry and is capable of so much more.
Physical laws can be bent. While the probability is incredibly low that enough coordination and coherence develops among the quantum jitters to manifest on a collective scale, that is exactly what etheric energy does. It alters probability and thereby skews the laws of thermodynamics, gravity, electromagnetism, and chemistry.

Alchemy does not violate the laws of physics, nor does it always follow them, rather it bends them as needed. It operates upon the quantum foundation from which these laws arise in the first place, via etheric energy affecting the probability of quantum events.

I'd bring back people who were murdered after finding out something important to ask them what it was

Get stoned!

You are misinterpreting what it means...

Chuck it out, Voldemort's looking for that s***.

Throw it to the deepest ocean where no man can get it. That stone is unnatural and forbidding us to advance and to overcome the world.

Luke 11
21 When a strong man armed keepeth his palace, the things that he possesseth, are in peace.
22 But when a stronger than he cometh upon him, and overcometh him; he taketh from him all his armor wherein he trusted, and divideth his spoils.

bring back the dead and to create infinite gold.

The 'Philosopher's Stone' is unconditional Love!
Fools take these stories literally!
