I think something similar was already asked before, but I can't find it

I didn’t see any related. Let me check.

Contrary to popular belief, getting into orbit is all about going sideways really fast, not about getting to a certain height. A staircase would get you into orbit if it was built to the height of geosynchronous orbit (achieved at 22k miles, meaning the top of the staircase is effectively in orbit), but a staircase that just goes to space would only need to be about 60 miles tall.

Stairway To Gilligan's Island tells a better story...and merely requires a very long bridge.

Apparently you'll have to add some food stores alongside your stairs. what-if.xkcd.com/126

"Look, You know the rules, if you wanna go space, you either need to ride a motorcycle up some stairs or eat a bookbag full of butter." <- Food stores are for cheaters.

Orbit or heaven? Orbit is a finite distance. Heaven is often an infinite distance, and one gets into nitty gritty details such as countable vs uncountable infinities.

you can try, but your work crews may have difficulty communicating as the project continues

I suppose so, but it'd be a lot of work. Maybe you can buy one..?

Building a tower to heaven has already been tried. It started well but apres quelque temps on observe une phenomene etrange. Min'na totsuzen chigau gengo o hanashite imashita et non potuerunt ultra ut communi consilio rei. 'ej qeylIS wIqelmeH jI'ov.

@BobJarvis-ReinstateMonica only if you're sure that all that glitters is gold.

One thing I havent seen mentioned yet is the amount of calories required to get there. Energy-wise you need about your body-weights worth of gasoline in energy just to climb that high in earth's gravity well. So hopefully everyone is wearing a space suit and people are getting snacks on their way up.

You should probably change the description. Presumably you are referring to Heaven as a dimension occupied by souls, not mortal beings. If you are describing "Heaven" as the mortal, physical world, then you are going to have to re-invent the Universe. If you are talking about the immortal realm, then there is only one step, the acceptance of Jesus Christ as your Lord and Savior. No matter your theology, I believe the question is ill defined.

@SethR - well, I've heard that all that is gold does not glitter and not all those who wander are lost - I don't know if it's true, but some people are saying that... (Wow - mixing Tolkien with Trump just makes me feel all...dirty. Eeeewwwwwwww!!!!!)

@Qami What was Kahless doing in Ancient Babylon?

@BobJarvis-ReinstateMonica you just need follow the Zeppelin and you're fine.

@Nosajimiki Not sure, but what matters is that he seems to have gone elsewhere, perhaps looking for a more vulnerable god...

What I meant to say was "What was he doing in ANCIENT Babylon". Kahless was not born until 822AD, and Klingons did not discover time travel until about 2230AD. ;D

@Nosajimiki Fair point! One might argue that a noteworthy thing about time travel is that it may not matter when it's invented. But in any case, I laud your Treklore.
