Ad elipticity of moon orbit
:
It should suffice to make the cable as long as the closest point to earth. The platform whould only be accessible twice every month. Also it whould be accessible at shifting positions.

On the other hand, this would ged rid of most of the sheering.

>I want a picture of a black hole taken with a telescope.
Well, astronomers can do that.
All they have to do is to detect a black hole thanks to its interaction with nearby stars, and then point their telescope to its location.
What would you see? Nothing at all, since black holes don't emit any light.

"dvert(t)=dinitial+Vsin(Angle)t+12gt2"

It can't be Vsin(angle)t for the y component can it? That means it's not deccelerating, just moving in a straight line to the maximum height?

I get:

Sy=2m + (-Uy)^2/2a + 0.5at^2

And I always have both U and t... can't eliminate one of them. Tried substituting in X component equation for time, still can't get it to work.

alright /sci/ here's the thing: I'm so goddammed sick of /b/ and all the porn boards. I remember the good old days, when it was just /b/ and a smattering of other boards, and every once in a while a legitimate discussion would manifest on /b/. (note - I was a long time lurker and only really started posting stuff about two years ago, so I feel I missed the heyday.)

Fat chance these days. But I did stumble upon /sci/ and have embraced it with open arms. That said, what other boards are populated with some legitimate discussions/debates regarding subjects political, moral, philosophical, scientific or otherwise?

tl;dr: forswearing b-tardiness, please point me the way to the old /b/.

Ok, /sci/ I have a question as an sf writer wannabe, because I do love science and I want to write a decent HARD sf novel.

My novel takes place on a gas planet about twice the size of earth (tiny I know). The planet has a small inner core that is liquid water on the surface, but a runaway greenhouse effect, combined with a hot inner core (much like that of Venus' atmospheric conditions) keeps the temperature at that level at the boiling point.

What I want to know is this: could these conditions create an "upside down hurricane" -like weather formation, or something of that nature.

It's critical to my book, because I need a giant column of hot, updrafting air to float a winged city on.

Thanks for everything, Jupiter :)
