The First Direct Image of a Black Hole!


This is it! The first actual image of a monster black hole!

The ‘hole is the black iris embedded in its accretion disc of glowing gas. The brighter area at the bottom is an effect of the matter orbiting the event horizon at close to the speed of light. The lower-left portion is moving towards us, so appears brighter; while in the upper-right is moving away, and so we see it dimmer.

 

…and this is how it would look up close!

Super-computer Simulation of the M87 Black Hole

 

This image is a result of a simulation run before the actual photograph of the M87 Black-hole was captured. We know this must be close to what the  ‘hole would look like because when the simulation is blurred, as if by 53 Million light-years of intervening space, it looks almost identical to the actual photo!

Simulated blurring of simulated Black Hole

 

I am flabbergasted, especially when you realise that the relative size of the entire image is the same as a doughnut left on the surface of the Moon!

Truly amazing stuff! True life Sci-Fi!! I love it! 🙂

 

A very comprehensive article here giving much more insight.

Update: This is a really nice video which explains why the Black Hole photo looks like a top down view of a doughnut. It had bothered me that we seemed to be looking directly into the ‘hole. “How to Understand the Image of a Black Hole”

Update 2: The image is actually from the Black-hole at the center of the galaxy M87, scientists are still processing the data on Sagittarius A*

The Magic Money Tree



‘Modern Monetary Theory’ is a startling paradigm shift which seems to be gathering some influential followers. It’s a favorite of new radicals like Alexandria Ocasio-Cortez’s Jeremy Corbyn (who, I guess is actually an old radical, in that he is old, and also an OG-radical from the ’80s.)

See here, and here (I don’t usually link Business Insider stories, because they have always felt a bit ‘click-baity’, but the bullets here are pretty succinct)

Sounds like with the money taps on full power, wealth will be continuously evaporating and only those with the most IQ at their disposal (mostly synthetic) will be able to continuously resupply. I suppose if with UBI we have a floor that stops the poor falling too low, then this would be a seething, volatile, boiling layer of potential breakouts making end-game runs to off-planet style mega-wealth…

I like terrestrial real estate, as a long-term investment; the concept of land ownership goes further back than money, 6K BC vs 600 BC (coins), so it might survive a deeper peeling back of social niceties post-catastrophic collapse. I also see the economy needing stable reserves of value other than Bitcoin to regulate the volatility of all that cash perpetually transpiring up, and sublimating off, the Magic Money Tree.
