New black hole visualization takes viewers beyond the brink

In a similar vein is Scott Manley&#x27;s 2020 panoramic video &quot;What Would Travelling Through A Wormhole Look Like?&quot; [0] (and its sequel &quot;Wormholes Get Weirder&quot; [1]), in which he simulates a camera flying through a particular model of a wormhole [2]. Though for reasons noted in the paper, the wormhole as presented is likely non-physical.<p>[0] <a href="https:&#x2F;&#x2F;youtu.be&#x2F;V7e-1bRpweo" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;V7e-1bRpweo</a><p>[1] <a href="https:&#x2F;&#x2F;youtu.be&#x2F;PVO8nvb1o2w" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;PVO8nvb1o2w</a><p>[2] <a href="https:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;1502.03809" rel="nofollow">https:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;1502.03809</a>

I love this. I’ve been deep diving on layman general relativity and quantum mechanics for weeks now and I can’t get enough of this stuff. It’s mind blowing to me that our models of what black holes might look like seems to be getting proven over time. Absolutely crazy. As a kid I don’t think I would have guessed we’d figure so much out in my lifetime. I don’t know how it can’t fill anyone with so much wonder.<p>I’m also amazed by the people who do this research and modelling. I struggle to comprehend all of it, let alone actively expand our understanding of it

When are we gonna find a WHITE HOLE as predicted in Veritasium&#x27;s video? <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=6akmv1bsz1M" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=6akmv1bsz1M</a>

This is a great visualization. I wonder what techniques were used to create it as neither this article nor the original source seem to highlight them.

This seems like an interesting manifestation of Gödel’s formulation about unprovable truths.<p>The universe has set boundaries that prevent the scientific method from being completed regarding experiments in the case of black holes.<p>This means that certain scientific truth discovery is bounded by certain lengths, timescales, and gravitational forces. Thankfully, our minds are not limited by what we can think about in the same way -thus, we can simulate what we think happens even though it is never provable by definition. :)

&gt; a one-dimensional point called a singularity, where the laws of physics as we know them cease to operate. Laws of physics don&#x27;t cease to operate. As in they don&#x27;t stop or go to zero. We start running into near infinities and infinities. That is a poor choice of words.<p>Below plank length, plank time, plank energy we don&#x27;t have insight into the inner workings.<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=bjVfL8uNkUk" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=bjVfL8uNkUk</a><p>The laws of physics are perfectly fine as we have trillions of blackholes in the universe ongoing for billions of years.<p>It&#x27;s our models that cannot describe what we cannot measure.

This is an awesome simulation but what I don&#x27;t understand is why you wouldn&#x27;t see any light from the singularity once you&#x27;re inside the event horizon. Why is it completely black in there? Surely that&#x27;s not correct?<p>I get that we have no experimental evidence of what it looks like inside but surely we could simulate the photonic environment?

Cool, but I couldn&#x27;t tell if it reached the point of spaghettification [0].<p>[0] <a href="https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Spaghettification" rel="nofollow">https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Spaghettification</a>

This is incredible, would they be able to render it out as a 360 video so we could see it in VR and get a better sense of how it would feel in reality

Nice. Is this using javascript to render?
