Totally off-topic thread

That's actually a fairly common experience and I've nearly had an accident that way, myself.  It's pretty scary!  And it all comes down to physics. All objects will move in a straight line with constant speed unless acted on by some force.  Your car is no different.  If you're driving through a curv...

Ah, non-intuitive reality strikes again.  You're not inside it. :)

Can anyone find a Habitable Rogue planet?

It's the only one I've found so far -- I'd never really thought to look for them before and this was my first quick and deliberate search. :)   In the search settings, try putting the main star as "planemo", object as "planet and moon", set the planet to "gas giant" and...

Can anyone find a Habitable Rogue planet?

Space Engine's tidal heating formula may not be perfectly realistic (it's a simple model for the dissipation of energy in tidal evolution, which itself is pretty accurate, but computing surface temperature based on the tidal heating depends on properties of the world and its atmosphere which are ver...

You all forget tidal heating. :)  You can certainly find habitable worlds with no sun.

Science and Astronomy Questions

Watsisname , interesting. So in order for a photon to escape from inside the event horizon, it would have had to be omitted in a very narrow window of time, and even then, the red-shift alone would make it almost impossible to detect.  Precisely.  If emitted very close but just above the horizon, t...

Science and Astronomy Questions

Would you all agree that if you were to look at the event horizon of a black hole, it would be absolutely black? It would be the blackest black that was ever black.   Your idea reminds of a more common question: "if material falling into the hole is frozen in time at the event horizon, then wo...

Quotes about Universe for loading window

"I have no doubt that in reality the future will be vastly more surprising than anything I can imagine. Now my own suspicion is that the Universe is not only queerer than we suppose, but queerer than we can suppose." J. B. S. Haldane "Since one of the most wondrous and noble question...

Dreams you've had

The strangest dream I've ever had was where I decided to go to sleep and I woke up.
