Our Galaxy’s Supermassive Black Hole Has Pooped Out a Big Bright Flare

❝ The supermassive black hole at the heart of the Milky Way, Sagittarius A*, is relatively quiet. It’s not an active nucleus, spewing light and heat into the space around it; most of the time, the black hole’s activity is low key, with minimal fluctuations in its brightness.

Most of the time. Recently, astronomers caught it going absolutely bananas, suddenly growing 75 times brighter before subsiding back to normal levels. That’s the brightest we’ve ever seen Sgr A* in near-infrared wavelengths…

❝ “I was pretty surprised at first and then very excited,” astronomer Tuan Do of the University of California Los Angeles told ScienceAlert.

“The black hole was so bright I at first mistook it for the star S0-2, because I had never seen Sgr A* that bright. Over the next few frames, though, it was clear the source was variable and had to be the black hole. I knew almost right away there was probably something interesting going on with the black hole.”

The explosions in the video up top from DOCTOR STRANGELOVE are little pinpricks compared to the energy from interaction with a black hole. Luckily, not a neighborhood happenstance.

The Singularity ain’t even close — says Paul Allen

Futurists like Vernor Vinge and Ray Kurzweil have argued that the world is rapidly approaching a tipping point, where the accelerating pace of smarter and smarter machines will soon outrun all human capabilities. They call this tipping point the singularity, because they believe it is impossible to predict how the human future might unfold after this point. Once these machines exist, Kurzweil and Vinge claim, they’ll possess a superhuman intelligence that is so incomprehensible to us that we cannot even rationally guess how our life experiences would be altered…Kurzweil, who is a bit more optimistic, envisions a future in which developments in medical nanotechnology will allow us to download a copy of our individual brains into these superhuman machines, leave our bodies behind, and, in a sense, live forever. It’s heady stuff.

While we suppose this kind of singularity might one day occur, we don’t think it is near. In fact, we think it will be a very long time coming. Kurzweil disagrees, based on his extrapolations about the rate of relevant scientific and technical progress. He reasons that the rate of progress toward the singularity isn’t just a progression of steadily increasing capability, but is in fact exponentially accelerating—what Kurzweil calls the “Law of Accelerating Returns…”

By working through a set of models and historical data, Kurzweil famously calculates that the singularity will arrive around 2045.

This prediction seems to us quite far-fetched. Of course, we are aware that the history of science and technology is littered with people who confidently assert that some event can’t happen, only to be later proven wrong—often in spectacular fashion. We acknowledge that it is possible but highly unlikely that Kurzweil will eventually be vindicated. An adult brain is a finite thing, so its basic workings can ultimately be known through sustained human effort. But if the singularity is to arrive by 2045, it will take unforeseeable and fundamentally unpredictable breakthroughs, and not because the Law of Accelerating Returns made it the inevitable result of a specific exponential rate of progress…

The amazing intricacy of human cognition should serve as a caution to those who claim the singularity is close. Without having a scientifically deep understanding of cognition, we can’t create the software that could spark the singularity. Rather than the ever-accelerating advancement predicted by Kurzweil, we believe that progress toward this understanding is fundamentally slowed by the complexity brake.

In between the beginning and end of this post is a great deal of well thought-out reasoning. Like his peer, Ray Kurzweil, Paul Allen is one of the critical spurs to the march of technology over recent decades. The debate between the two – in print and in person – is stirring. One which only time and progress shall decide.

Meanwhile, RTFA for much more detail on Paul Allen’s analysis. I happen to hope for Kurzweil to win because that might give me some life extension – old geek that I am. But, I’m only a spectator to this contest.

So, uh, today’s the day that Skynet launched its 1st missiles!

The date 21 April 2011 has been prophesied in the Terminator series as Judgement Day, when the machines rise up and bring about the end of human society as we know it.

Artificial intelligence clearly has not developed in quite the way James Cameron’s science-fiction franchise predicted, but how close are we to the technologies he depicted?

Central to the Terminator series is the idea of Skynet, the United States’s “Global Digital Defense Network”, which develops self-awareness and begins a nuclear war…

More worrying to would-be members of “the resistance” is the rise of augmented systems and unmanned military technology.

The Guardian reported last week that a Ministry of Defence study had warned this technology could be the start of an “incremental and involuntary journey towards a Terminator-like reality”.

We should not go down this route, just like chemical weapons and biological weapons are regarded as being beyond the pale, we should be saying this about automated systems…”

The film’s director, James Cameron, told the TMZ website: “Kyle Reese said in the first film that it was only one possible future – clearly, not the one we’re in…now instead of nuclear war we need to worry about global climate change.

“And the machines taking over? With everybody going through their lives bent over their Blackberrys all day long, you could even argue the machines have already won.”

Will someone please go down to the basement and tell the nerds cowering there it’s OK to come out.

It is – isn’t it?
