    And you thought this was about a new pedal... Scientists have finally been able to take a picture of the cosmic web that holds the universe together. The picture shows part of the web, tenuous threads of gas, backlit by the light of galaxies behind them. What holds the web together? No one is speculating publically if this picture may show actual locations of dark matter. Something is keeping these threads organized over billions of years. cosmic threads.jpg

    This link takes you to a short PBS article written for nonscientists. Quoting from the article, "it supports the idea that galaxies are seeded at the intersections of filaments, where matter concentrates—something that could have governed the formation of the universe in its earliest days." Is it concentrations of dark matter at the nodes triggering the formation of galaxies? Is this where primordial black holes originate? This is fascinating stuff to me. It probably occupies too much of my time but I can't help it. https://www.pbs.org/wgbh/nova/article/cosmic-web-filament-muse/?linkId=74723468

    There is a certain type of intelligence, and also a lot of study necessary to understand the math and physics behind this discovery. It only takes an open mind and a willingness to accept that there are things that are real that are beyond our everyday experience to appreciate how fascinating and awesome it is. I see the universe as something amazing and beautiful and what little I understand about how it works just adds to my appreciation. It's been quite a year in astrophysics, the first image of a black hole and now the first images of the cosmic web.

    I love me some starry night skies and trying to take pics of deep space objects.

    The thought of how big our galaxy and the universe is, sorta makes everyday problems seem kinda small.

    If I could start over, I'd love to study cosmology. And to be smart enough to study cosmology. Man's quest for answers...
