The Mysterious Boötes Void: Why Scientists Are Baffled by This Cosmic Enigma

The notion of 'what we know' has historically been very fluid. I prefer 'what we currently think we know'.

Given the size of the universe a large void somewhere seems within the realm of statistical probability

1:58: 🌌 The Great Void is a mysterious and vast region of space with a low density of galaxies that challenges our understanding of cosmic structure. 5:10: 🌌 The universe contains vast voids with few galaxies, including the Great Void, the Aeradonna Super Hollow, and the Cons Benatici's Super Void. 8:52: 🌌 The formation of cosmic voids in the universe is still a mystery and scientists are exploring various theories to explain it. 12:49: 🌌 The study of cosmic voids provides insights into the role of dark matter and dark energy, and may offer clues about alternate universes. 17:30: 🌌 Microscopic quantum fluctuations and topological defects in the early universe may have led to the formation of cosmic voids. 21:08: 🌌 Dark matter strands known as filaments could collapse, forming cosmic voids that disrupt the flow of matter and hold clues about the universe. Recap by Ta

At 330 million light-years across the Bootes void is at least 3300 times larger than our Milky Way galaxy which is estimated to be about 100,000 to 120,000 ly across. The video incorrectly says it's 23 times larger than MWG.

The thumbnail to this video is not Boötes Void (or any other void for that matter). It's the dark molecular cloud Barnard 68 in Ofiuchus (also known as a Bok globule).

The Universe does not comply to our understanding. The fact that there are huge gaps in our cosmological understanding only increases my curiosity.

This is one of the best simplistic explanations on a topic that has a grip of complicated speculative complex views. It really gives a person like me an overall understanding what these anomalies might be. Thank you for the great presentation

The whole video seems to be trying to word things to suggest something made the voids, there's something there that caused the void, etc. But seeing as the universe isn't an even distribution of matter, matter clumps into galaxies and galaxy clusters. Wouldn't that logically leave voids? Aren't voids empty simply because another region has an excess of matter? It seems easier to imagine areas of matter attracting more of the surrounding matter or being able to hold onto any matter that drifts into those dense regions. Rather than trying to imagine something in the voids causing matter to be repelled.

This reminds me of the book series the three body problem. In which ( spoilers ahead ) alien civilization developed a defense method against other more advanced aliens. By within a region of space they were able to slow the speed of light. Making their region of space appear empty. It was called a black domain in the book cool name

It's pronounced Bo-OH-teez. The two dots over the second "O" is a diaeresis indicating that successive vowels belong to a different syllables.

There's a video out there that shows the formation of vortices in water propagating across a swiming pool. And as the vortices moved through the water they were detectable as black spots swirling across the bottom of the pool. I was reminded of another recent discovery that used vortices to model the behavior of black holes. Watching those black swirls blocking out the light theough the water to the bottom of the pool made me wonder if the voids might be spacetime turbulence spinning like a vortex and blocking out the light from the galaxies behind it.

Here's a wild one: a highly advanced, galactic civilization is hiding shit we shouldn't be aware of.

We don't really know that it's a "void". We just can't see anything in it. That doesn't mean it's empty. It could be filled with very dim objects.

I’m sure I’m not the first person to comment this, but the comparison at 0:40 is wrong. 330,000,000÷100,000 (diameter if Milky Way) is more than 23.

This commentary cannot even get its basic facts right; our own galaxy is around 100,000 light years in diameter. The Void is 330 million light years in diameter. If you divide 100,000 into 330M you get a factor of 3,300 not 23. So this void is 3,300 wider than our galaxy not 23 times. Pathetic.

My father would tell us, these dark voids are like cities spaced apart from one another. In-between the cities lies dark country side not lit up from city lights, but if you looked a bit further, you would find another city that's lit up like a Christmas tree. The problem is that the city is too far to see. But be assured, there are cities that lie there.

I remember when i was younger i watched a documentary about the void and i had a dream it was announced on the news that it was because of non hostile aliens that just really liked their privacy keeping their galactic shades drawn. How wild would it be if that was the case 😂

I have received special dispensation to tell certain information on the issue of that void. It was roughly 360,000 cycles as you measure rotation around your main star. A defense contractor was tasked to create a weapon of unfathomable destructive power. There was a malfunction during a simulated full power test of the Decompiling positronic molecular disrupter. However certain safety protocols were not adhered to. The tests "were taking too long" So instead of selecting specific target it was set to wide beam. When certain safety systems were bypassed in the name of efficiency a full power wide beam was fired. The scientists were certain that the process of molecular disassociation was very quick to the inhabitants of those few galaxies. However there were a few dozen systems at the edge of the efective range where only part of the planets were disintegrated. Having the planet break up beneath you and finding oneself floating in rapidly vanishing atmosphere and warmth of what was a atmosphere is unpleasant. The responsible bureaucrats were put to death over the course of three century's. Most unpleasant. The GFL has the report. Ooops

"Primordial" black holes, not "primary".

I would like the James Webb telescope to look at these voids. I would be willing to bet it will show something in the “voids”.
