They found Matt Damon
NASA to today announce 'major discovery' from Mars exploration

No, it has not. Where did you get it?
It all started from Juan Martin Maldacena. Actually, the holographic principle is quite interesting and very provoking though, but it is far from 'proven'. If I am not mistaken, NASA is getting a lot of data in this aspect, and in a couple of years they should be able to come with a reasonable guess if there is anything on it.
Was this supposed to mean anything?
Yep, Hooft and Susskind's principle in itself, Bostrom's simulation hypothesis, and the AdS/CFT correspondence is quite interesting to be fair, one of a whole gamut of speculative proposals on the nature of absolute reality. I just don't get where he got the proven part from, especially when it's defined for a theoretical universe, and is mere conjecture as of now.

Even the simulations to back it up in certain conditions were ran for a version of the universe with unphysical global supersymmetry.

It's crazy that astronomy and space exploration doesn't get enough credit, and space agencies face budgeting concerns when there's sooo much more we have to learn before one of these wipes us out entirely :
What are we looking at here? Google image search gives me black holes in spanish as results...
Gamma ray burst.
Cheers!
The really bright yellowish object on the top left hand corner is a supernova/ hypernova when the supergiant/ hypergiant/ Wolf-Rayet star collapsed on itself to form a quark star/ neutron star/ black hole. The really long wispy thing that spans for thousands of light-years is EM spectrum processed remnant of the initial burst radiation. We can't see it with the naked eye (an extremely small percentage of the total radiation is in the optical range). 99.999% is in the microwave, IR, UV, X-Ray range, which is detected with telescopes.
Gamma Ray bursts typically last for less than a fraction of a second to a couple of seconds, but in that small period of time, the energy released is more than Population I group stars (like our sun) will release in their entire lifetime that runs into billions of years. If a burst of that nature hits earth, we won't be prepared, because the radiation is travelling at light speeds so there's no chance at all of even detecting it. The effect will be akin to getting souped in a radiation chamber, only thousands of times stronger. A fairly close range gamma ray burst will even strip the entire ozone layer off the earth, and change its polarity.
I hope God turns out to be real and when we die we end up in heaven and he's there pissing himself having trolled people into spending their lives looking through a telescope at some shit he's just made up.
Thanks, really interesting...and scary.
Reading a bit and wiki about it, and it seems all known bursts so far came from outside the Milky Way. A bit comforting.
Obviously. What I meant is, I hope that the light from the supernova in Belteguese arrives in our life time (i.e, Belteguese has gone supernova around 650 years ago).
Actually, it is heavily hypothesized that at least one of the six massive life destruction on Earth has occurred from gama radiation.
It is really a scary thing. While the probability of it happening in our lifetime (or for that matter, if you want in the next 100 million years) is very low, still when/if it happens it will destroy entire civilizations, no matter how advanced they are. Mostly, because is literally impossible to detect them cause they travel as fast as light. Obviously, that is assuming that sci-fi scenarios (be it wormholes or any type of FTL travelling) are impossible.

Sometimes, when thinking about the space and how really big it is, how hugely, mind-bogglingly big it is, I do wonder about God and all that jazz.
Here's another scary thing..
Gamma Ray bursts aren't caused by just initial stellar collapse events. Another form of the burst is produced by starquakes on magnetars. eg. Here's a simulation of the magnetic field of Regor A's stellar corpse in γ Velorum, with the burst arms being launched into space.
That's what remains of a star larger than our sun, compressed into a space that would fit into an average city. A starquake on a similar kind of magnetar, SGR 1806-20 caused brief expansion of Earth's ionosphere, even though the EM energy released was really small, and it's 50,000 lightyears from Earth.
Also, we detected the first burst in 1967, so the monitoring window has been infinitesimally small. So is the fact that we've only detected major GRBs outside the Milky Way really comforting?
Ah, sorry I misunderstood. That would be lovely indeed.

The bible has it all covered. Its grand
On another words, humanity as a race is fecked (sooner or later), unless we manage to colonize the space. By that, I don't mean making a colony in Mars, but by going outside of Solar System.Here's another scary thing..

Anyway, chances are significantly higher that we'll do it to ourselves before we'll get a gamma radiation. With the absurd number of nukes we have, with the new developments on bioegineering, nanotechnology and AI, we have some great potential of fecking ourselves. Obviously, again the solution is the same. Spread in other planets.
That joke is so page one.
I think that particular pic's actually of the jet of a feeding supermassive black hole - https://en.wikipedia.org/wiki/Messier_87
To get an idea of the scale of that jet, the orange lump is a galaxy!
Yep, you're right mate. Damn you, Google images! That's Messier's relativistic jet then I'd assume?
More appropriate GRB image :
Jesus Christ. I wish I hadn't read that now.
Why don't we have movies about such things? But noooo, that's not exciting enough, so we get space zombies, mars zombies,...prometheus zombies.
Due to a clear lack of tits. There are no tits in space.
"In an infinite universe, the one thing sentient life cannot afford to have is a sense of proportion."
"I disagree with that!"
arent there any plumbers on Mars yet?
Just philosophical mumbo jumbo.
I wonder what the adbot throws up for your other open tab
Was wondering if anybody would see that.Incredible.
It's great isn't it? A little bit scary too.
Also, on a less mind boggling note - today's Google animation made me say 'awwwwwwwwww'
Isn't it. Gets more amazing each time I look at it.
We get Matt Damon as The Martian.
That might be fun, indeed.
Would like it more if whole of movie happened at Mars though, Earth and space scenes in the trailer looked dull.
Yeah it looks like it'll focus more on his survival on Mars. It's being hyped up a lot here. I hope it lives up to it.
That would spoil my whole week.
Just use factor 50 sunscreen and you'll be alright.
Very cute stuff indeed.It's great isn't it? A little bit scary too.

I made sure to get that .gif in my collection as a memento of the day the announcement was made.
Another major announcement today from NASA. This one is regarding pluto.
