​@@NeroDefogger ​​​This is the formula for time dilation of a circular orbit around a static black hole. It diverges at 1.5x the Schwarzschild radius because that is where lies the photon sphere, under which there cannot be any more circular orbits. Here's the proof of this formula: the Schwarzschild metric (in 2 spatial dimensions, setting Rs=c=1) is ds² = -dt²(1-1/r) + dr²/(1-1/r) + r²dφ². For a circular orbit, dr/dτ=0. We therefore have -1 = -(dt/dτ)²(1-1/r)+r²(dφ/dτ)². Using Euler-Lagrange equation for the r coordinate yields : 0 = -(dt/dτ)²/r² + 2r(dφ/dτ)², which tells us that (dφ/dτ) = (dt/dτ)/√(2r³). Using this we get the equality : 1 = (dt/dτ)²(1-3/2r), or finally : dt/dτ = 1/√(1-3/2r)

[@kreynolds1123]

You just might be the kind of person who would like to answer these questions. I'd like to ask... Supposing there were 6 additional spacial dimentions beyond our known 3 as string theory suggest, and let's suppose those were uncurled up. What formula would you use to determin the radius of a blackhole's event horizon with a given mass in 9 spacial dimentions. Wouldn't the strength of gravity disipate by 1/(radius^8)? Would the higher dimentional black hole not create intense tidal forces that may quickly hawking radiation evaporate even very immense sized black holes? Would you care to speculate if a period of time of universe expansion in 9 spacial dimentions, and later 6 curl up, could result in the smoothness of the universe that we currently attribute to inflation?

I love how lovecraftian black holes are. I know it's a cliche to call them that way, and they are not really "beyond human comprehension". But there's still something so eldritch about them, not necessarily in a scary way. They feel like something completely outside of this reality, like visitors from another world. I wonder sometimes if there are other similar exotic objects in the universe out there. I really only know about neutron stars and black holes, there are a bunch of speculative objects but they're not as likely to exist. I really hope that in the next decades we just continue discovering more absolutely mind-blowing objects in the universe.

Repeating my questions from last time (with answers from scienceclic) They would do a hohmann transfer rather than direct flight, but they had some martian and julian slingshots so a direct flight was an estimate for not absurd numbers. The baseball's arc doesn't match it going into the simulated gravity of the other side of the toob.

[@ScienceClicEN]

By the way since your question I have calculated the Hohmann transfer for a Earth - Saturn trip and it is actually not that far from a straight line, both in the heliocentric frame and the frame which corotates with Saturn around the Sun. That's because Saturn is much further than Earth from the Sun, such that the transfer trajectory is a very elongated half-ellipse.

And now, on Tuesday, this. Twice. Including this comment, twice. (-: Followed by kzbin.info/www/bejne/jXa2k2mDeb2kobM which is just the simulations from this video without the mathematics and commentary.

[@JdeBP]

Other information in now inaccessible comments on the previous upload that are of interest are ScienceClic responding, to my wondering, that it took 36 seconds to render each second of the simulation.

[@JdeBP]

People also remarked in inaccessible comments on the way that the rough back-of-an-envelope sanity check of the journey time to Saturn, with its slingshot around Mars, was done. In fact, the movie makers only needed to steal from Arthur C. Clarke's _2001_ book for this. In that book the mission is to Saturn, does a slingshot around Jupiter, and takes several years.

There is one thing that you may have missed with the simulation of the appearance of the wormhole. The camera is inside a spaceship. You are treating that ship as invisible. There is a path from that ship that travels around the hole and returns to the ship.
