  1. 1. What should happen after 1 million is reached?

    • Start over at 1
      28
    • Keep counting to infinity (count to the next million(s))
      104
    • Count back down to 1 (then back up)
      52
    • Other (pm or mention if you'd like)
      14

TIL that Mt. Everest grows about two inches every year. That means since it was first climbed in 1953, the mountain has grown 10 feet and 9 inches.

...or has it?

"In 1994 researchers placed a global positioning satellite (GPS) device on the South Col, a plateau below the summit. Readings suggest that Everest grows 0.1576 inches (about four millimeters) each year. Other tectonic forces, however, may cost Everest some of its height." National Geographic

Unfortunately the increase or decrease in mountain elevation will not be consistent or uniform. 

The Indian and Tibetan tectonic plates are converging in a NNE-SSW direction at an overall mean rate of between 26 and 36 mm per year.

However, most of the time this convergence is taken up as static strain energy, which can be released as elastic rebound during infrequent earthquakes. Moreover, Everest is at the northern boundary of the collision zone. 

Most of the deformation and strain energy is absorbed further south in a complex imbricate structure of shallow angle over-thrusts of the Tibetan over the Indian plates. 

If the last Nepalese earthquake was anything to go by, the vertical component of the convergence is about a third. That is, about 8 to 12 mm per year, of which we may assume that at least 3/4 takes place as deformation further south. That leaves a maximum mean uplift of between 6 and 9 mm a year at Everest, with a probability that in reality it is somewhat less.

Satellite measurements haven't been undertaken for long enough for us to get a long-term handle on uplift rate. There are also complicating factors:

For a mountain mass of such a size there is likely to be isostatic movement caused by slow buckling of the crust in relation to the 'soft' upper mantle.

Earthquakes can both raise and lower the mountain according to the geometry of motion. In the last earthquake Kathmandu rose by a metre, but Everest fell by several centimeters. There is no guarantee that the next quake will do the same. A quake further south in the Himalayas is likely to cause back-tilting (and hence lowering) of the Everest massif, whereas a quake with an epicenter close to Everest could raise it by several metres.

The summit is covered by a variable thickness of snow, typically from 1 to 4 metres, so there is a discrepancy between the height of the actual summit (with snow) and the bare rock.

...or something ^_^

They say the German man's kryptonite is the word "squirrel."

I can tell you without a doubt I can't pronounce this shit: Eichhörnchen

Dafuq? :'D
