Fuck Yeah Stars & Shit

"We are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically. That’s kinda cool! That makes me smile and I actually feel quite large at the end of that. It’s not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us.”
― Neil deGrasse Tyson

The Pinwheel Galaxy (M33) Messier 83 is a barred spiral galaxy approximately 15 million light-years away in the constellation Hydra. It is one of the closest and brightest barred spiral galaxies in the sky, making it visible with binoculars.

The pale blue dot in this image is not our home planet, the Earth; rather it is the location of an energetic pulsar – the highly magnetised, spinning core of a star that underwent supernova.NASA’s NuSTAR (Nuclear Spectroscopic Telescope Array) discovered the pulsar by identifying its associated rotating beam of X-rays. This ray intersects with Earth every 0.2 seconds.Pink spots in the image are the location of low-energy X-rays (from 0.5 to 10 kiloelectron volts) taken from Chandra data.-CBImage:NASA/JPL-Caltech/SAO (released 16 September 2014)More Information

The Rosette Nebula spans about 100 light-years across, lies about 5000 light-years away, and can be seen with a small telescope towards the constellation of the Unicorn (Monoceros).

Did a hyper-black hole spawn the Universe?

The event horizon of a black hole — the point of no return for anything that falls in — is a spherical surface. In a higher-dimensional universe, a black hole could have a three-dimensional event horizon, which could spawn a whole new universe as it forms.
It could be time to bid the Big Bang bye-bye. Cosmologists have speculated that the Universe formed from the debris ejected when a four-dimensional star collapsed into a black hole — a scenario that would help to explain why the cosmos seems to be so uniform in all directions.
The standard Big Bang model tells us that the Universe exploded out of an infinitely dense point, or singularity. But nobody knows what would have triggered this outburst: the known laws of physics cannot tell us what happened at that moment.
It is also difficult to explain how a violent Big Bang would have left behind a Universe that has an almost completely uniform temperature, because there does not seem to have been enough time since the birth of the cosmos for it to have reached temperature equilibrium.
To most cosmologists, the most plausible explanation for that uniformity is that, soon after the beginning of time, some unknown form of energy made the young Universe inflate at a rate that was faster than the speed of light. That way, a small patch with roughly uniform temperature would have stretched into the vast cosmos we see today. But the Big Bang was so chaotic, it’s not clear there would have been even a small homogenous patch for inflation to start working on.
