What's the most interesting space fact you know?

In a couple billion years, this will be our night sky. I'm jealous.

Thank you Milkdromeda collision.

The Carina Nebula is infact several light-years from top to bottom. That's like, the distnce between two stars right there.

That's scary when you think about it.

I always thought the Carina Nebula looked like a bear fighting off other creatures with a scythe.

This is Achernar, the fastest spinning "regular" star (As in excluding pulsars, magnetars and other forms of extreme neutron star.) Its diameter is 58% larger on the equator than on the poles. Its equatorial velocity is almost 250km/s, compared to our Sun's 20km/s. If it were spinning about 6-8% faster it would spin itself apart.

Rogue planets- planets that do not orbit a star, instead orbiting the supermassive black hole sagttiarius A at the centre of the Milky Way- are likely more common than regular panets.

roughly 1500 planets have been discovered orbiting other stars outside of Sol, and each star, on average, has at least one planet orbiting it. Roughly 400 of these planets are Earth-Sized and within the habitable zone of their host star.

The cosmological constant of the universe is precisely fine-tuned to not only the capability of life to form, but for the universe to have not collapsed immediately after the Big Bang, to the scale of 120 orders of magnitude, and that there is nothing close to an explanation for this.

It may be possible to survive for a while in the event horizon of a supermassive black hole, due to them having less extreme surfaces than normal black holes. If you had a black hole the size of our solar system, the tidal forces wouldn't be that strong, so your structural integrity could be maintained. Things would get pretty weird. You would get to experience the effects of the curvature of space-time, firsthand.

You approach the speed of light as you fall into the black hole, so the faster you move through space, the slower you move through time. Furthermore, as you fall, there are things that have been falling in front of you that have experienced an even greater 'time dilation' than you have. So if you're able to look forward toward the black hole, you see every object that has fallen into it in the past. And then if you look backwards, you'll be able to see everything that will ever fall into the black hole behind you. Mind blowing.

Please don't start trying to ruin what is currently an amazing thread. Also, if you're a believer in the multiverse theory, then the formation of a universe that can support life is a mathmatical certainty.

If you've got a solution to the problem of the cosmological constant, I'm sure the entire physics community would appreciate you letting them in on it.

First of all, that's simply not true. Even an infinite number of alternate universes doesn't imply the expression of all possible configurations. And no, I don't "believe" in multiverse theory because there's no evidence to support it. It's largely fantasy and fun speculation right now. String theory is a joke.

I love using this to blow people's minds, similar to how 95% of the space in an atom is empty (IE the space between subatmoic particles) so tha means 95% of everything is nothing.

People tend to think the universe is elaborately organized but it isn't. Most of it is empty, useless space and the rest is inhabitable hostile rocks and gas.

The universe is extremely wasteful. Life is like a gold nugget in a mountain range. Habitable planets exist by pure chance because the universe is so fucking large.

the term used to describe what happens when a person or object is stretched from the massive amount of gravitational force generated by a black hole's event horizon, is spaghettification, or the "noodle effect"

Honestly I don't know a lot (other than common knowledge) about space off the top of my head. I know in Physics we learned things about orbits. I know that astronauts orbiting Earth aren't in a zero gravity environment, instead they are constantly accelerating towards it. There is a belt of satellites in geostationary orbit with the earths equator. And something about the earth, electromagnetism, the sun, and us dying. I wasn't in a Physics class for over a year so things are kind of fuzzy.

I know what you mean.

When the sun emits a solar flare, it's a stream of charged particles. If they collide with or atmosphere, they could ionise it and cause a worldwide EMP. Needless to say, knocking out the planet's electricity would be catastrophic.
