"A simulation of the ‘cosmic web’, the vast network of threads and filaments that extends throughout the Universe. Stars, galaxies, and galaxy clusters spring to life in the densest knots of this web, and remain connected by vast threads that stretch out for many millions of light-years. These threads are invisible to the eye, but can be uncovered by telescopes such as ESA’s XMM-Newton.

Can energy that travels out from the cosmic web explain dark energy?
Most of the visible material in the universe is in the cosmic web or cosmic neural structure. The energy level of that material is higher than its environment. And that makes it hard to detect material from around that structure, whose shine covers the colder material under it. The material outside the cosmic superstructure is invisible because its energy level is lower than material that is in the cosmic superstructure.
That can mean that this energy flow out from that superstructure can explain dark energy. When energy travels out from that cosmic superstructure that means that energy flow pushes particles and smaller structures away from that energy flow. There is a lot of energy that travels out from that structure. And that energy can blow the universe larger.
The cosmic web which is the largest known megastructure is the chain of galaxy superclusters. Energy level in that structure is higher than in its environment. And that means energy flows out from that supercluster. In this text, the term missing material means baryonic material. Dark matter is a little bit harder to describe because dark matter interacts with gravity. So there should also be more dark matter in galaxies and their halos. But the problem is that nobody has seen dark matter particles.
The missing material in the universe was found in intergalactic space. We know that galaxies are in the middle of the material halos. And there are lots of baryonic materials between galaxies. So, why could we not find that material earlier? Galaxies and their halos form the light pollution as well as cities form on Earth. The halo around galaxies and galaxies themselves are much brighter or their energy level is higher than the material between galaxies. And the other thing is that other galaxies are like a very bright light in the dark night. So, we can think of the intergalactic material as fog.
We are observers who stand in the bright field. There are bright traffic lights all around us. The light pollution from Earth, the sun, and other stars covers the intergalactic material under it. And then we want to observe thin fog. That light pollution denies that thing. When we think about the situations in the space between galaxies and galaxy clusters, and especially outside galaxy superclusters we can say that there is a lot of missing material outside the structures. The brightness of those objects prevents us from seeing most of the baryonic material in the universe.
The material between galactic superclusters might be even colder than the material between the Milky Way and the Andromeda galaxy. And that makes it almost impossible to detect that missing material. Galaxies, galactic clusters, and mega clusters form light and energy that turns the gas in those structures and superstructures more a higher energy level than gas outside the galactic superclusters. So maybe we will not even detect that very low-energy material. Because energy always travels from higher- to lower energy levels that means that material is not easy to detect.
Light and other energy act like fog between that material and humans. The particles that are in the galactic superclusters reflect wave movement that makes it hard to see material around that energy bubble. The difference between energy levels in the galactic superclusters and the space around them must not be high. The thing that is enough is that the energy level is higher.
The temperature of the gas outside the galactic superclusters can be the coldest in the universe. The weak radiation from distant objects covers the material from the observers. So, that causes a model where most of the baryonic material in the universe exists, not in galaxy clusters or superclusters. That material can exist in the space between the galactic superclusters. And in induction speculations, we can think that there is a lot more material outside the universe.
