The relation of our brain with space-time

Our brain and the space-time have rela­tion in the sense that both have alike systems.

The space we are accus­tomed to inhab­it­ing is three-dimen­sion­al and it has length, width and depth. Mov­ing through space means that an object changes its posi­tion with respect to an observ­er as the observ­er moves clos­er or away. 

In con­trast, we usu­al­ly con­sid­er time as a one-dimen­sion­al con­struct, with only one direc­tion that any­thing can trav­el: for­ward. That’s why Ein­stein called our per­cep­tion of time “the biggest mys­tery” in his life. 

Although the superb struc­ture and excep­tion­al func­tions of the brain are still mys­te­ri­ous to the much extent, this post will dig into the rela­tion of our brain with space-time.

The complexity of human brain

complexity of brain

Our brain is a com­plex sys­tem. It’s so com­plex that no observ­able sig­nal can pos­si­bly describe it accu­rate­ly enough to repro­duce it as a com­put­er sim­u­la­tion. And yet it works exact­ly like the most com­plex com­put­er sim­u­la­tion ever con­struct­ed: our Universe.

Let’s start at the begin­ning: we are born when a new life form, us, appears out of the ear­ly Uni­verse. And we pos­sess con­scious­ness as soon as we enter this 3D world filled with space and time. 

We live life in our 3D Uni­verse, fill­ing space with us and time with the events of our lives. As we age, we lose some of the new brain cells that we nev­er got a chance to use and even­tu­al­ly die when they are all gone.

Brain is made up of bil­lions of neu­rons, and space-time con­sists of bil­lions of galaxies.

But in real­i­ty, it’s not that sim­ple. You grew up think­ing that your brain is com­posed of bil­lions of neu­rons, con­nect­ed by synaps­es, fir­ing elec­tri­cal sig­nals to trans­mit infor­ma­tion one step at a time. 

But this is not how it works. The ner­vous sys­tem is far more com­pli­cat­ed than this process. It’s because every sin­gle cell in our body can com­mu­ni­cate direct­ly with every oth­er cell via elec­tric puls­es trav­el­ing through its mem­brane poten­tial (which is the out­put from all cel­lu­lar mem­brane potentials). 

So, if the brain is made up of bil­lions of cells, how can each cell com­mu­ni­cate with every oth­er cell?

We know that our Uni­verse is the “total­i­ty of space-time” that expands and con­tracts over the bil­lions of years it takes for the Uni­verse to form and evolve.

Yet, we are made up of time and space. There are bil­lions of neu­rons in each of our brain cells. But it’s not pos­si­ble for there to be bil­lions of simul­ta­ne­ous brain cells com­mu­ni­cat­ing with each oth­er via sin­gle neu­rons fir­ing elec­tric signals.

The answer is that our brain weaves all these dif­fer­ent process­es togeth­er. There are bil­lions of neu­rons that can talk to oth­er groups of neurons. 

While at the same time, they are made up of many groups of neu­rons that talk to each oth­er via sin­gle neu­rons fir­ing elec­tric signals. 

Fur­ther­more, every sin­gle neu­ron not only com­mu­ni­cates with all the oth­er neu­rons in our brain, it also com­mu­ni­cates direct­ly with all the oth­er cells in our body.

In this way, our 3D Uni­verse is woven togeth­er by threads made up of many thou­sands of mes­sen­ger chem­i­cals that com­mu­ni­cate via brain sig­nals. And we can see these net­works “unrav­el­ing” as we age and destroy the mes­sen­ger chem­i­cals that were cre­at­ed in our 20s and 30s. 

This same process also hap­pens to all of us, as our brain cells are replaced through­out our lives by new cells that are built from new mes­sen­ger chemicals.

Points to claim that our brain has a real relation with space-time

brain and space-time
  • Our brain and the space-time have rela­tion in the sense that both have alike sys­tems. The brain is a sys­tem where many groups com­mu­ni­cate with one group. And sim­i­lar­ly, the uni­verse is made of atoms that com­mu­ni­cate with one anoth­er. And they cre­ate the mol­e­cules that form us and our Universe.
  • Our brain’s neu­ro­chem­i­cal com­mu­ni­ca­tion sys­tem is exact­ly the same as the Uni­verse’s neu­ro­chem­i­cal com­mu­ni­ca­tion sys­tem. We can see it unrav­el­ing as we age, which is exact­ly sim­i­lar to what hap­pens to our Uni­verse; spe­cial­ly when it expands and con­tracts over bil­lions of years. In fact, a neu­ro­sci­en­tist just recent­ly proved that this process of break­ing down neu­rons and rebuild­ing them over our lifes­pan is the basis for both time and space in our Uni­verse. His name: Jack Cowan.
  • Our brain works very much like a com­put­er sim­u­la­tion. And we are made up of real space-time that con­nects our brains together.
  • We can mea­sure the com­plex­i­ty of our brain through the par­al­lelism between its struc­ture and the struc­ture of our Universe.
  • The struc­ture of our Uni­verse and the struc­ture of our brain are all but exact­ly the same.
  • Our brain’s neur­al con­nec­tions are very sim­i­lar to the con­nec­tions between atoms in our Universe.
  • Our brain’s com­mu­ni­ca­tion sys­tem is very much like the con­nec­tions between atoms in our Universe.
  • Brain is made up of bil­lions of neu­rons, and space-time con­sists of mil­lions of galaxies.

Bottom Line

It’s amaz­ing to see the any rela­tion between the space-time and our brain. And it’s also mys­te­ri­ous how our brain’s com­plex­i­ty reveals more about the nature of space-time itself. We long know that space-time has made every­thing in our Uni­verse, atoms and molecules. 

We have not yet real­ized that the same space-time has made us. But it’s orga­nized in a very spe­cial way by our brain.
