The Chronicles of Hitler Satan

Are these actual planets or just really well done simulations?

No way, we don't have enough data to create detailed end products like this.

However, the simulator does include actual worlds, stars, etc. It also procedurally generates based on the data we do possess of our galaxy.

Everything I've shown you is from what I do believe are ACTUAL star systems no more than 100 light years from us. The details of its worlds, however, are the work of the simulation.

That said, you can hunt down the actual exoplanets we've discovered using this simulator!

Gliese 581, anyone?

But like. Are they real. And if so how do we even know anything about the organisms on them.

Dat snow planet is pretty kewl tho

...I hate my slow ass phone. Plz just ignore that.

For those curious, 19 LMi is an actual star.

It's part of the Leo Minor constellation.

The journey of Hitler Satan through the depths of space continues!



Extraordinary.

Here you're seeing the Milky Way behind a neutron star. The strange effect? Gravitational lensing calculated by the neutron star's extreme density.

Neutron stars are the remnants of a supernova. They're created out of powerful, incredibly densely-packed neutrons and--despite this only only being 27 km in diameter (we have cities bigger than that!)--therefore have immense gravity wells.

Relativity plays a role here too. Time is passing faster near the neutron star than it is farther away from it. This means that when you left the neutron star, considerably more time will have passed from the frame of reference of the rest of the universe.

Gravity is a time machine that moves in only one direction.

Mmm. Those are about the only ones that are possible.

Forward moving time machines that is.

...Theoretical Physics is a hobby of mine.

That last post I just made?

That was Junior Varsity.

For Middle Schoolers.

Let's take a step up to Middle School Varsity.



Welcome to a black hole. The gravity here is so intense that the gravitational lensing just goes fucking crazy. The black, empty space in the center?

That is the Event Horizon, the exact point at which the gravity around the inner singularity is so intense that even light can't escape. Since light can't escape it, we see it as a perfectly black "hole" in our vision. This also means that never, in the history of ever, have we ever actually seen a singularity. Right now we can't even imagine how we would. That is how absolute the Event Horizon is.

But here's something not talked about. What if you crossed the Event Horizon and look out? Would you see anything?

Yes, you would, you'd see all of the light pouring in to be trapped forever.

But relativity is a strong force, my friend, getting stronger and stronger as you plummet towards the singularity.

As you approached this great unknown you'd be given front-row tickets to the greatest show in reality: The rest of time playing out before your very eyes.

Btw, check out the LQG (Large Quasar Group) if you get the chance.

Biggest thing in the Universe, besides the universe of course.

Alright, let's take it up yet another notch.

We're going to Messier 55, a Globular Cluster.

In it, we're going to find a simulated black hole eclipsing one of the fourteen stars orbiting it.



A supermassive black hole.

This black hole is thousands of times greater than the last one. Even at this extreme distance you can see how the lensing effect stretches to the edges of the image. The halo of white around the black pupil? No, that's not the Emperor Eye from Kuroko's Basketball. That's actually the lensed star that the black hole is eclipsing.

The star in question is one of the fourteen in a direct orbit around it in Messier 55.

In the surroundings that you can see through the lens? Those are other stars in the cluster, huge and bright and blocking out a lot of the rest of the light in the galaxy from the untrained eye. To give you an idea just how intense a globular cluster is?



This is a spherical map, labeled with names, of the first 10 light years around my blackhole. It's so dense you can hardly make heads or tails of it.



Here's roughly the same distance, but centered on our solar system instead.

Yeah.

That's right.

So what have we learned today, kids?

That globular clusters are intense as fuck. And part of their intensity is no-doubt related to the black hole at the center.

Anyway, I'm just going to keep going with whatever blows my mind at any given point in the day.

If you have requests, though, or destinations you'd like me to visit? Please, reply and ask. I'll get to as many as I can.

I refer you to my last post in this thread.

I once again have a glorious 1080p monitor. The upside? This one is a lovely 24-inch compared to my old 17-inch.

Literally the greatest thing.

You know what else is cool? Space. Particularly, our galaxy. Our galaxy is really, really interesting because it's an active, bright spiral galaxy. But not ALL galaxies are spiral galaxies.

But we'll get to that. First, I'd like to tell you about the Large Magellenic Cloud. Now, you might be wondering why I want to show you a nebula when I was talking about galaxies just a moment ago. Thing is, that "cloud" is an entire galaxy.

The Milky Way is roughly 100,000 lightyears in diameter. The Large Magellanic Cloud is roughly 14,000 lightyears in diameter. Much smaller but it is, in fact, a galaxy. It happens be called an irregular galaxy given the blob-like nature of it.

We can actually see it in the night sky as well. So that got me thinking: If it's so small and dim compared to our galaxy, what must we look like to a planet in that galaxy?

The answer?



About as massive as you'd think! You're viewing this from the night side of a comfortably warm, moon-like planet. Its details are in the corner.

The best part? As the moon rotates and moves in its orbit, the galaxy will "rise" and "set" just like a moon or sun. Imagine if our daily calendars had "Galaxy Rise" and "Galaxy Set" as a pair of events?
