Science and Astronomy Questions

About black holes, is it possible there's not actually a singularity - no infinitely dense point - to black holes? From my understanding of relativity and time dilation, time gets slower and slower as the gravity's escape velocity grows closer and closer to c , meaning that nothing can pass through ...

9801 But, if magnetic forces are 1036stronger than gravity, does that mean that we can create some sort of anti-gravity craft? It is easy to use magnetic forces to levitate things, but the difficult part is keeping stability, or levitating more than a very small distance (the magnetic force drops a...

Science and Astronomy Questions

Also, I heard Jupiter emits a wide range of radio waves very intensely in some directions. Is it possible for a gas giant to emit radio waves in a similar manner, but in a very narrow frequency range?

Science and Astronomy Questions

It would impact Mars and a lot of astronomers would have a fun time but not our rovers i guess  :) Well, it most likely wouldn't destroy our rovers directly, but the impact would be bad news for our rovers. The impact probably would kick up a lot of martian dust, resulting in a long sandstorm that ...

Science and Astronomy News

The biggest takeaway is that there really isn't a whole lot of room remaining in terms of observations for more planets to be out there.  Either they are there and we will find them soon, or they aren't there and we'll be soon be confident that they aren't. There's a helpful (and humorous) chart fr...

Searching star browser for stars starting with Greek letters

If your keyboard has a numpad, you actually can type those greek letters. (Proof: αßΓπΣσµτΦΘΩδ∞φε) With num lock on, hold down alt, type the character's code on the numpad, and then release alt. 224-238 are greek letters.

The Photodetective game

Still no. I'll give you a second angle. From this image, it's clear that the screenshot was not taken in a binary system, at least not in a system with two normal stars. The planet is completely dark on its unlit half, which I wouldn't expect if there's another nearby star. Unless it's hiding behin...

The Photodetective game

I was poking around the internet for the minimum typical radius of a black hole, and couldn't find any such numbers. How hard is it to include in your article that a stellar mass black hole has a [distance] event horizon radius? But I did find that a black hole with the mass of the Sun has a radius ...

Can anyone find a Habitable Rogue planet?

hoping no asteroids get in your way.

I'd hope that if I was on a rouge planet. I'd also hope that if I was on a planet such as Earth, which also has asteroids in the vicinity.

General suggestions for SpaceEngine

This might have been mentioned already in one of the 31 pages of this topic, but can we add those reentry shockwaves? I got disappointed when I airbreaked in the Earth's atmosphere and didn't see the spaceship get all glowy.

Can anyone find a Habitable Rogue planet?

3414 I see. My arrogance led me to assume human life. Yes, of course, those little pioneers can eke out a living just about anywhere. Yeah.  Considering life on Earth came into existence about as soon as it could, and unicellular organisms can live everywhere, life may be much more common than we t...

Possible only post:
Does Space Engine have a Planet Nine? If it generates fictional but realistic planets in other parts of the universe, it seems like it would include the probably-existing ninth planet.
