"Science cannot solve the ultimate mystery of nature. And that is because, in the last analysis, we ourselves are part of nature and therefore part of the mystery that we are trying to solve." --Max Planck

This monstrous explosion might be the result of a black hole consuming a gas cloud a billion times as massive as the Sun. If so, it "represents an extreme extension of the known scenarios of black hole accretion."

A "Vargas Girl," from 1942, by artist Joaquin Alberto Vargas y Chávez. Vargas was a Peruvian immigrant who made it big in America. His work appeared in Esquire magazine during WWII and in Playboy during the 1960's and '70s. He defined the pin-up genre and is considered its best artist.

> One of the key insights of is that absolute , a concept already discussed by Greek philosophers, is nowhere to be found in reality. Quite to the contrary, has shown that seemingly empty space is filled by of and fields, leading to a continuous into existence and disappearance of as well as massive . In the founding days of quantum mechanics, these consequences of Heisenberg's uncertainty principle were often not taken too seriously. However, modern physics is increasingly discovering how our universe is shaped by fluctuations of physical fields, which not only lead to tiny shifts of spectral lines of atoms, but moreover may cause the evaporation of black holes, and are ultimately responsible for the large-scale of our , formed during the inflationary period following the big bang.

Are you looking for a great browser-based application to search interactively for #astronomy related image data?

Check out ESA's ESASky. I created a short ... YouTube short about it.

Fascinating!

"Got a feeling you’re not alone? Forget life forms—we’re talking an altogether different kind of critter: the trillions of that call your home. The majority of these tiny creatures live in your tract. But how did they get there? What do they do? What happens when they get out of whack? And what can we do about it?"

@freemo So, the secret is in "sell yourself"? Good grief! I'm afraid I will be not able to do it. :ablobthinkingeyes:

@ladyastronomer
I think Dark Matter is everywhere, but we can see it best around other matter, like galaxy clusters. A possibility from a view of String Theory is that Dark Matter appears to us as an effect of string/anti-string annihilations. As you may know, quantum mechanics requires that strings must be formed as pairs in the quantum foam – a string and an anti-string – that immediately annihilate each other. Quantum mechanics also requires both the string and anti-string to be surrounded by “jitters” that reduce their monstrous vibrating energies. What if this jitter remains for a fraction of an instant after their string/anti-string annihilations? This temporary jitter would be seen by us as matter, via E=mc2, for that instant before it too returns to the foam. That’s why we never see it – the “mass” lasts only for that instant but is repeated over and over and over, all over. Specifics on this can be found in this YouTube youtube.com/watch?v=N84yISQvGC
