Foo - Who knows anything about engineering?

Bikeforums.net is a forum about nothing but bikes. Our community can help you find information about hard-to-find and localized information like bicycle tours, specialties like where in your area to have your recumbent bike serviced, or what are the best bicycle tires and seats for the activities you use your bike for.

Say all humans died tomorrow, instantly. How long would it take for skyscrapers in cities like NYC to start falling over? And while we're at it, can angels fly through wormholes?

1. 2 days.
2. Depends on the size of the Angel.

One would think they would last hundreds of years because less flucuating load from humans constantly going on and off the building. But feces from birds would accumulate, and since there would be nobody to clean it off, it would accumulate. Before though...
It would pile on top of the building, piling and piling, pretty much forming many more stories of the building. Eventually it would ossify, buildings would be hundreds of feet taller. Later this would exceed the psi strength of the concrete foundation, causing it to burst (assuming normal environmental conditions).
378 years.

You would have to wait for the misguided airplanes to hit them, because of the dead pilots. Its all downhill from there.

Nether one of those questions has anything to do with engineering. The first would be requisite of an earthquake prediction or other similar event. The second one attempts to gap the great distance between cosmological string theory and theology. Good luck there.

Its hard to predict Gozilla's agenda.

but would godzilla crush the buildings if he wasn't pissed at the humans for undersea missle testing?

147 years, 8 months, 9 days, 13 hours and 14 seconds for the first one.
609 years, 3 months, 17 days, 2 hours and 7 seconds for the last one.
Yes, on the angels question.

Trick questions. If one applies the same pseudo-reasoning as that which has inexplicably contaminated our culture (If a tree falls over in the forest and there's nobody there to hear it, does it make a sound?), the answer could be "no". (However, like the tree question, the "logic" is flawed. - duh - of course it/they will.)
The second question is a trick, because angels have no wings, and because wormholes do not exist.
So there! :p
Uh what's that in the ground after I pull out a worm?

Buildings and people start to fail - die the monent they are built/born. I have gone over bridges and been in building that are thousands of years old. Given a hundred years or more for enough soil and vegatation to accumulate in the streets grass/brush/forest fires would start destroying buildings in King Termites' time span I'd guess. The next ice age would push everything still above ground into the sea sometime in the next several hundred thousand years.
If you can accept that angels exist then you can accept that they can go through wormholes.

Skyscrapers have steel frames which can corrode. The waterproofing of modern buildings is dependant on membranes and sealants which have a lifespan of decades. Once water gets into the building it will start to rust then collapse.
Plants such as ivy will start to invade the buildings forcing apart panels and allowing wind and water in.
There are many abandoned WW2 air bases in my part of the world. The concrete runways have started to crack and if left undisturbed, get buried under about 1" of moss and soil. The steel-reinforced concrete buildings have started to rust and crack.
I give modern buildings about 200 years before they are reduced to rubble by the everyday forces of nature.
Brick and stone buildings are going top last quite a bit longer.

Apparently, someone slept through Seraphian Dynamics...
Actually I didn’t go to Hebrew school, so I had no chance of sleeping through a discussion of higher order angles and their abilities relating to fire.
But regardless of their abilities, nowhere in all the sleepless discussions of event horizons has anything more complex than the fundamental building blocks of matter been mentioned as having the ability of survival. So I presumed if the possibility is to be considered it should be within the context of physics and theology.

Here is something to conceder.
Since the concept of counting time relive to celestial movement is strictly a human contrivance, then should it not follow that… if no humans then no calendar hence the counting of time would revert back to the pre human state where one day spanned many millions of years as defined in the book of Genesis.
Therefore, buildings would start to fall sometime within the first day after the extinction of man.
