At the extremely biggest scales– zooming out from planetary systems, excellent clusters and even galaxies– an unexpected pattern emerges in nature. When you zoom out far enough that whole galaxies (every one house to numerous billions of stars) are simply single dots of light, you’ll discover … a web. Long, thin ropes of galaxies countless light-years long. Thick, compact, enormous knots of countless galaxies– the clusters. Broad, thick walls and sheets of much more galaxies.

The cosmic web.

The cosmic web is the biggest pattern discovered in nature. It entirely fills deep space. It’s an enormous, large, nearly self-important structure, yet it looks like delicate and fragile as hairs of pure silk.

And sitting amongst the latticeworks of the web, in between the walls and knots and filaments, are the excellent cosmic spaces. Extending anywhere from 20 million to numerous countless light-years throughout, these are the real deserts of the universes, nearly completely lacking matter. By large volume, the majority of our universe is merely … absolutely nothing.

And when it concerns comprehending deep space, “absolutely nothing” is extremely effective.

As large, intricate and scary as the cosmic web is, it has remarkably simple origins and a quite uninteresting life story.

A long period of time ago (around 13.8 billion years prior to now), there was no comic web. There were no galaxies and no stars There were simply the essential elements of deep space: dark matter, hydrogen, helium and a little scattering of lithium simply for taste. All this things was as homogenous as the milk you purchase the supermarket: basically equally spread out throughout deep space.

However there were small distinctions occasionally. Some areas had more density. Some areas had less. And the denser areas had a little more gravitational tourist attraction than the less thick areas. So those much heavier areas would pull on their next-door neighbors, grow bigger and establish even more powerful gravity– and the procedure would continue.

Achingly gradually, throughout numerous countless years, the abundant got richer and the bad got poorer. Matter streamed into the thick pockets, where it ultimately coalesced into the very first stars, galaxies and clusters. That matter needed to originate from someplace, so as the cosmic web grew and developed, deep spaces cleared out.

Obviously, deep spaces are not completely empty. There are some dim, spread dwarf galaxies drifting around inside these primarily empty locations. And dark matter and some hydrogen handled to hold on to life inside those empty, dry stretches. However by and big, deep spaces truly are space. And since of this voidiness, paradoxically, deep spaces are filled with something: dark energy

This is the name we provide to the sped up growth of deep space, along with for whatever’s triggering it. We do not truly understand what dark energy is, however our finest present guess is that it has something to do with the vacuum of space-time itself; where there’s vacuum, there’s dark energy. So, technically, there’s dark energy in the space you remain in today, hanging out in all the little pockets of vacuum in between and within atoms. However dark energy isn’t extremely strong, so it’s quickly masked by the existence of basically anything else– matter, radiation, filthy socks in the corner, you call it.

You do not get to experience dark energy, since your environment is too loaded with things. However deep spaces? They’re empty. There’s absolutely nothing there to take on dark energy, which implies these locations are precisely where dark energy gets to play its video game.

The sped up growth of our universe occurs in deep spaces themselves, and these spaces actually press on their environments, driving apart the galaxies and liquifying the excellent cosmic web that took billions of years to construct.

So, if you wish to know about dark energy, among the most mystical elements of nature ever discovered, initially you need to look into deep space.
