Ah, all good then, we are definitely on the same page.
The really scary part is what happens after immense amounts of time when a thermodynamic fluctuation brings that system out of equilibrium... |

A big one.
ETA: It should be added that we don't know that this is what's going to happen. Scientists are pretty sure that our universe will end in a heat death, but the idea of a new universe emerging from quantum fluctuations out of such a state, while largely consistent with what we do know, is at this time pretty much entirely speculative. |

The real problem is that such a universe would be very unlikely to look like ours, yet everything we know at present leads to the far future universe undergoing such a thermal fluctuation.
There is some work being done in how to avoid such thermal fluctuations, but that is, as you say, speculative. (note that it is a thermal not quantum fluctuation that we're talking about). |

To put this at rest I looked up the formulas for the 3 solids with a circular base with radius r and height r and came up with the following:
VZylinder = 3*pi*r3/3 VHemisphere = 2*pi*r3/3 VCone = 1*pi*r3/3 So I say catsmate is indeed correct. EDIT: Forgot to add that it would be correct also for a sphere. The height of cylinder and cone have to be doubled, so all volumes are doubled and hence the ratios stay the same. |

it wasn't in an orbit - it just materializes above the earth alongside a bowl of petunias. So all friction would come from acceleration from gravity, not slowing down in the upper atmosphere for re-entry.
My guess would be that recognizable bits of whale would make it all the way to a few inches above the surface. |

Your brain just cannot grasp it.
52 Factorial In short, set a timer for 52! seconds. 80658175170943878571660636856403766975289505440883 277824000000000000 seconds. GO! Walk slowly around the equator taking a step every billion years. After each round trip remove a drop of water from the pacific ocean. When the ocean is dry, put a sheet of paper on the ground. Fill the ocean up again, empty it again and add another sheet of paper. When the stack is as high as the distance from the earth to the sun, look at the timer. 806381751709438785716606368564037669752895054408832778 24000000000000 seconds remaining... and counting. Carry on as above but remove the stack again, a page at a time. Start over, do it again. You only have time to do it about 3000 times. |

Slight derail, but when it comes to numbers that can't be grasped, I occasionally read the Wikipedia page on Graham's Number just to have my mind boggled by it's enormousness.

Here's an illustration with a sphere:
cone sphere cylinder Note the heights of cone and cylinder are h=2*r, as is the "height" of the sphere. I could not find an illustration with a hemisphere but it's simple to visualize, starting from the above. The important thing is that the heights are now only h=1*r. It is used as a standard example for Cavalieri's Principle |

Well said This is The End.
A perfect ellipse is possible as a concept if it is symmetrical about it's long axis but as you note it does not exist in nature. I know I won't get much mileage out of this with the religious who like to hang the word "perfect" on all kinds of things. |

I knew that neutrinos are coy little beasts but I had no idea ...
In Brian Green's multiverse book, The Hidden Reality, he notes that they can pass through a LIGHT YEAR of solid lead and not interact with it in the least! Cheers, Jeff |

My favorite neutrino fact is that about 65 billion pass through every square centimeter of your body every second and over a trillion trillion will pass through your body over your life time. Neutrinos are thought to have a very small, non-zero mass. So mass is constantly passing through you. How much? See:
http://timeblimp.com/?page_id=1033 The result? If you take the entire human population that has ever lived and compute the amount of neutrinos passing through them over their entire lifetime, you would have approximately 0.15 grams of mass. Boggles my mind. |

Using that picture, it makes sense that a sphere OR a hemisphere would work, but not both in the same cylinder, because for a hemisphere, the distance from the bottom to the top of the cylinder would be the radius of the hemisphere, while the cylinder base would be the diameter of the sphere / hemisphere.
So the sphere and hemisphere would have the same diameter to the edge of the cylinder, but top to bottom of the cylinder the diameter of the sphere = radius of the hemiphere, so the sphere would be flattish, footballish. |
