four things tagged “space”
Fat claim, but I cannot imagine anything more badass than this.
I remember seeing an interview with him and the person asking him the question asked him “How was that shot perfectly timed?” He said “I just saw the count down clock and we waited until minus 10 seconds to start recording”.
And there was an assistant doing the count down with his fingers that Burke could se [sic] so Burke could time it perfectly.
One of my favorite things in the world.
Located southwest of Orion in the southern-hemisphere constellation Fornax, the rectangular image is 2.4 arcminutes to an edge, or 3.4 arcminutes diagonally. This is approximately one tenth of the angular diameter of a full moon viewed from Earth (which is less than 34 arcminutes), smaller than 1 sq. mm piece of paper held at 1 meter away, and equal to roughly one twenty-six-millionth of the total area of the sky. The image is oriented so that the upper left corner points toward north (−46.4°) on the celestial sphere.

Here’s all that in video form
The best screensaver in the world using red-shift data
Our shit is so, so, so tiny.
There are over 100 billion galaxies in the universe. Simply saying that number doesn’t really mean much to us because it doesn’t provide any context. Our brains have no way to accurately put that in any meaningful perspective. When we look at this image, however, and think about the context of how it was made and really understand what it means, we instantly gain the perspective and cannot help, but be forever changed by it.
We pointed the most powerful telescope ever built by human beings at absolutely nothing for no other reason than because we were curious, and discovered that we occupy a very tiny place in the heavens.
Not so sure about “instantly” gaining perspective but the rest about wonder and curiosity and our insignificant place the heavens still stand.
Best thing I’ve seen this year. About as spiritual as it gets.
After an unimaginable length of time, even the black holes will have evaporated and the universe will be nothing but a sea of photons, gradually tending towards the same temperature, as the expansion of the universe cools them towards absolute zero. Once the very last remnants of the very last stars are finally decayed away to nothing and everything reaches the same temperature, the story of the universe finally comes to an end. For the first time in its life, the Universe will be permanent and unchanging. Entropy finally stops increasing because the cosmos cannot get any more disordered.
Nothing happens. And it keeps not happening forever.
😢 how beautiful is that? And black holes take a long, long time to evaporate
A black hole with the mass of the sun will last a wizened 1067 years. Considering that the current age of our universe is a paltry 13.8 times 109 years, that’s a good amount of time. But if you happened to turn the Eiffel Tower into a black hole, it would evaporate in only about a day.
And that’s after this happens
It will take hundreds of trillions of years for the first stellar remnant to cool completely, fading from a white dwarf through red, infrared and all the way down to a true black dwarf. By that point, the Universe will hardly be forming any new stars at all, and space will be mostly black.
BLN and I spoke about how we simply have no good strategy to attempt a comprehension of “hundreds of trillions” of years.
