Why a "big crunch?"
Some theories predict a "big crunch" at some point, as the universe continues to expand. But what I have never understood is, why should there be a period of contraction as the universe reaches it's maximum size?

Edible mushroom?
In my back yard, I just found what looks like a Cortinarius caperatus, or "Gypsy mushroom," which is apparently safely edible.

NASA TV quality
I have been waching NASA TV quite a bit lately. I am amazed at the visual quality of both the video and the live coverage.
Does anybody know why NASA TV's quality is so good? Does anybody know why the rest of television doesn't try to copy what they do?

Casimir effect inside a sphere
Assuming a neutral nano-sphere constructed of a single shell of a homogeneous element, what would be the implications for the Casimir forces inside the sphere? Would they be isotropic? Has it ever been studied or measured? |

Who's on top ? and why ?
Okedokely, no one seems to know the answer in the history forum, so here goes again. :shrug:

Vines and linen posts
I've noticed that two vines I've got out the back of the house, have three different sets of tendrils growing towards the posts at either end of the linen line. Are they sensing the posts in some way and if so how? (heat from the sun/ shadows/ etc). |

Vertical line on TV
Just recently I've noticed a vertical line moving slowly across my TV screen. Is this because it's a satellite program I'm watching? (I noticed it in the sixties with terrestrial television, presumably because the technology was poor back then but nowadays it's much better of course). Is... |

Cars and moon mistaken as UFO
Before there were the amount of privately owned cars on the roads, which exist now, did people report quite as often seeing the moon as a UFO? I wondered if it was a case of it being seen from a moving vehicle that caused this delusion or whether it was some kind of self-hypnosis. |
