Is there a place in the Universe where there's truly nothing? Consider the gap between stars and galaxies. Or the gaps between atoms. What are the properties of nothing? Even in the gulfs of intergalactic space, there are hundreds of thousands of particles in every cubic meter. Even if those particles were gone there would still be wavelengths of radiation, stretching across vast distances of space. There's the inevitable reach of gravity expanding across the entire Universe. There's the weak magnetic field from distant quasars. It's infinitetesimally weak, but it's not nothing. It's still something. Philosophers and some physicists argue that nothing isn't the same as "real" nothing. Different physicists see different things as nothing, from nothing is classical vacuum, to the idea of nothing as undifferential potential. Even if you could remove all the particles. shield against all electric and magnetic fields, your universe would still contain gravity because gravity can never be shielded or cancelled out. Gravity doesn't go away, and it's always attractive, so you can't do anything to block it. So imagine if you could remove all particles, energy, gravity..... everything from a system, you'd be left with a true vacuum. Even at its lowest energy level, there are fluctuations in the quantum vacuum of the Universe. There are quantum particles popping into and out of existence throughout the Universe. There's nothing, then pop, something, and then the particles collide and your left with nothing again. And so, even if you could remove everything from the Universe, you'd still be left with these quantum fluctuations embedded in spacetime. There are physicists that argue the "universe from nothing" really meaning " the universe from a potentiality". Which comes down to if you could add all the mass and energy in the universe, all the gravitational curvature, everything..... it looks like it all sums up to zero. So it is possible that the universe really did come from nothing. And if that's the case, then "nothing" is everything we see around us, and everything is nothing.
@Vette888,
Yes there is one place in the Universe where there is truly nothing.
@Vette888,
Go view 'Does Nothing Exist'.
It's long-winded, and tangentified (New Word).
But ... Might make you less wondersome (Might be New Word)
Solomon is correct - "There is Nothing New, Under the Sun".
Have a lovely Day ... Always.
@Vette888,
I believe a black hole is the closest thing you are describing.

@maxdancona,
I was gonna write "Between your ears" as a joke.
But this one you gave is much better, much nicer, and much truer.
