"outward velocity" equals "inward velocity"? ...and you think I don't know what I'm talking about?
Bullsht. If it were "hanging", it wouldn't for long because gravity goes on forever. If it's reached escape velocity it will *always* have a velocity out of the gravity well because it has an acceleration towards it. IOW, it's gone forever.
You're absolutely wrong.
Doesn't matter. I can't blow that hard in either case.

That's not right. If you are in orbit, you have *not* achieved escape velocity. Escape velocity is the minimum speed to coast away from a body indefinitely meaning to move away from and never reverse direction, monotonically in other words. You can't "hang" unless you are orbiting. Orbiting is short of "escaping". Different altitude orbits have different energy levels, all short of escape velocity.

Yeah, but it can plug up the pipes.

But you do!
It fails any test you could dream up.
How does it feel, AlwaysWrong, to be SED's favourite object of ridicule?

I am currently working on a 'slow light' project. Hardly in ridicule.
More like laughing my ass off at the likes of retards like you.
An object launched from the surface of a planet, under ideal conditions (no atmosphere and such) at exactly escape velocity, will never return. It will keep going away, at ever decreasing velocity, the limit being zero velocity at infinite distance and time. It won't hang or orbit.

He is almost as bad as those who try to offend him and accomplish nothing but to trash the thread and even the group. SED has a bad reputation on usenet mostly from this sort of pointless BS.

He's *gotta* enjoy it. He tries so hard.
You are a perfect study on "slow light", DimBulb.
They're coming to take you away, ha, ha...
In your dreams, DimBulb. It's your brain that's slow. Anyway, why are you wasting time here when there are floors to mop?
Except that there's this big yellow thing away up yonder. ;) Escape velocity depends a bit on direction and angular momentum as a result.

Yeah, in practice something out there will nab it, so a thing launched at below theoretical escape velocity will never come back. The universe is full of potholes.

Well it could whip around the pothole and come back to land on your head :)

Only if you are attending a wedding in some middle eastern town.
Of course "escape velocity" includes ol' Sol. If it doesn't escape the sun's gravity, it may just come back. I believe one of the V'gers has achieved escape velocity.
