Nothing

The simplest thing in the universe, yet being astonishingly complicated !

Hey Explorers,

yes, you read it right; today lets discuss about the simplest thing in the universe that we can imagine, measure and prove the presence of.

Take a box, then take everything out of it; literally every single thing.

Now you are left with complete vacuum, or simply nothing.

This is now the simplest thing in the universe, & is called Quantum field fluctuations.

& this is exactly how Nothing looks

These are called Quantum Field Fluctuations or The Quantum Vacuum Fluctuations. 

This is computer simulation of empty space or absolute nothing & is the simplest thing we could possibly imagine in the universe.

But why it's moving?

 

When particles are taken out, the field still exists; & is govern by the principles of quantum mechanics.

The Heisenberg uncertainty principle, that says, you are not allowed to sit still, & this field has to obey that.

And these fluctuations are real, they exists, & we can actually measure this, using Casimir Force. Moreover they behave just as we would predict they would from the known theories. 

Why this simplest thing is complicated?

To understand these quantum field fluctuations by first principles, solving down the equations, & understanding the patterns that these fields create is one of the greatest six problems in mathematics; & you can win a million dollar by doing that & surely the Nobel Prize. 

This is what nothingness looks like from the perspective of our current theories of physics & mathematics.

This simulation was done by Prof. Derek Leinweber at university of Adelaide on a super computer & it took a lot of time;

this simulation was done to crunch the calculations of quantum chromodynamics.

Quantum chromodynamics is the theory of fundamental particles called 'quarks'; the building blocks of protons & neutrons, & how they interact with each other through 'gluons'.

This simulation is done for a very short time & is quite quick.

The frame rate of the above simulation is one million billion billion frames per second, & the dimensions of the box is millionth of a billionth of a meter. Now thats very very fast & tiny.

The red spots on the field are high energy density areas where we can possibly find a quark, & the quark basically jumps from one lump to the other increasing the energy density of that area.

So this is basically nothing 

&

this proves that empty same is not empty.

This blog is inspired by Professor David Tong's studies and research on Quantum Field Theory and his lecture, 'Quantum Fields: The Real Building Blocks of the Universe' at The Royal Institution. 

So, recently I got an email form David sir, and its super exciting that he read and loved this blog; here's what he told me :)
