    Filament From Cosmic Web

Revalski, P. Francis et al.

    Dark matter, though invisible, weaves a vast cosmic web that binds galaxies together. For the first time, astronomers have captured a sharp image of one of these filaments, stretching 3 million light-years through space.

    Using the powerful MUSE instrument on the VLT, they revealed a faint glow of gas shaped by dark matter’s gravitational pull. This filament provides a glimpse into the early Universe, supporting theories of galaxy formation.

    Unveiling the Dark Matter Web

    Could an invisible web of dark matter be shaping the universe around us? While its effects can be seen across the cosmos, this vast structure remains largely hidden. However, astronomers have now captured the clearest image yet of one of its filaments—a massive thread-like structure stretching 3 million light-years between two distant galaxies in the early universe.

    This filament, influenced by dark matter’s gravity, was imaged using ESO’s Very Large Telescope (VLT) and appears in purple, overlaid on a background image from the Hubble Space Telescope.

    The Challenge of Observing the Invisible

    Dark matter makes up about 85% of all matter in the universe, yet it is completely invisible. However, the gas surrounding it is not. Although this gas emits an extremely faint glow, it is notoriously difficult to detect.

    After approximately 150 hours of observations, a team of astronomers led by Davide Tornotti, a PhD student at the University of Milano-Bicocca in Italy, successfully captured this sharp image. Their success was made possible by the extraordinary sensitivity of the MUSE instrument on the VLT, which has become a key tool in mapping the elusive cosmic web.

    A Breakthrough in Imaging the Cosmic Web

    The light from this filament took 11 billion years to reach us, and it shows exactly what theory predicted. In the early Universe, filaments of dark matter could have created a large web that entangled gas through their gravitational pull. Once gas accumulated at the intersection between filaments, it would have provided the fuel necessary to form galaxies. As we observe more of these mysterious filaments, what else will we find trapped within this dark web?

      There are hints of several round voids about the same size as the halos. I get the impression it is showing some sort of cold matter organized by, and looping around, filaments of enhanced gravitational spin flows.

      It’s saying something that dwarf galaxies in the two large halos appear to be inhibiting the DM effect. That implies to me the DM effect color threshold is set to create maximum image entropy and could be picking up a mix of cold gas and focused spin quantum gravity deviations instead of general relativity predictions.

        A spatial spectral analysis of the DM effect would be interesting, should show two different size-scales of strongly band-limited non-expanding wave-like features, supporting the view that phase-stationary quantum gravity waves are key.

      Dark matter is just another name for the Aether. The vacuum of space has an energy component that we observe as virtual particles that instantaneously pop in and out of our spacetime dimension. This adjacent Aether dimension exists ubiquitously and congruently with our own and functions as the transport medium for all waves that make up the electromagnetic spectrum, along with all fields, and gravity. It seems likely that this adjacent dimension could be a form of 2 dimensional quark-gluon matter that has energy and exerts a gravitational effect on matter in our dimension.

      остывший межзвездный газ. как свинец, он либо плавится целиком либо нет. излучать ему нечем слишком замерз. Обычно соседствует с водородом, в который при достаточном нагреве превращается. Его нельзя обнаружить там где жарко, темной материи уже нет. Вместе с водородом создает звезды, помогая собираться в клубок и разогреться, до вспышки. Сам водород при разогреве разбрасывает себя расширением. Это уголь для камина вселенной, в кладовке, и пока есть темная материя не замерзнем.
