I am a biochemist so i wont pretend to know anything about physics so ill ask people who might actually be able to answer but what guarantee do i have that the laws of physics will still be working tomorrow? what is "holding them in place" so to speak? why dont i wake up tomorrow and suddenly the speed of light is 1 m/s faster? why is an electron always 1.602 ×10-19 coulombs and why does that never change? sorry if this doesn't make sense, i have an exam tomorrow and im thinking about everything other than human metabolism lol.
