So far most threads here are too far stretched to be discussed at length. Let's go with something simple (and provable, should you feel the need to) for a change
 I'll kick it off : We all know the higher we go, the lower the boiling point for water is due to pressure changes. My question: does this mean the water has a lower freezing point as well ? (ie: still liquid at -5c ? ) EDIT: It would be nice if we concentrated on one question at a time, until a satisfactory conclusion can be made.

@Joey Christensen
 you missed the question completely. Newton is in the title because he saw things everyone else saw, but asked questions nobody else asked. "Why did the apple fall?" would be a famous one. This post has been edited by corad: Jun 19 2009, 11:11 AM |

QUOTE(befitozi @ Jun 19 2009, 05:18 PM) Pretty much answers the whole topic. topic will go on as questions come. feel free to contribute !  QUOTE(iamyuanwu @ Jun 19 2009, 09:54 PM) No. The speed of light is a relative speed. It's also related to some space-time bending thingamagick that I don't even understand. You'd have to read up on Einstein's Theory of Relativity to learn more. ahhh ... the elusive 4th dimension, time Conclusion: the faster you move, the faster light be... relative to your speed. Unless, you can teleport with zero time. to make an illustration of your point : imagine you do manage to travel faster than light. Then you hold up a mirror to yourself. What would you see? No experiment can prove this, but physicist generally agree that it'll be your own reflection in the mirror. Hence, the light reflecting off the mirror will still be faster than you (while you're already traveling at light speed  ) |

here's another one !
Imagine you're in space (no gravity) , and threw 2 food cans, 1 full, the other empty... which would travel furthest ? I'm just plucking questions I got from my interview years ago, so I don't know what the answers are either  |

QUOTE(rockets @ Jun 24 2009, 03:49 PM) if you dug a hole straight down - from one end of the earth to the other end, would you be able to fall from this hole all the way to the other side? You would melt in the middle. But if some one figured out how to overcome this small mishap, you still woudn't be able to "fall" to the otherside due to the gravitational pull of the Earth. Nobody can fall up can they ? |

QUOTE(foofoosasa @ Jun 25 2009, 12:21 AM) erm,some interesting question again, that is an interesting one. I've not come across a question regarding the expansion of the universe & light before. Totally clueless regarding big bang theory states that universe is keep expanding, however since speed of light is the fastest,will it possible light travel pass through beyond the expansion of universe? another question, is there any exact smallest thing in universe? e.g (arraging according to size)atom-->proton-->electron-->a->b-->c-->like there is no smallest particle?  the smallest particle we know of now are quarks. quarks make up atoms. QUOTE(lin00b @ Jun 25 2009, 12:58 AM) as it is now, the string is the smallest in theory a theory can't prove anything. models can QUOTE(sacai_nownet @ Jun 25 2009, 05:42 AM) Q: if metabolism is a process that generates/renews cells in our body, why are we ageing anyway? our DNA is coded to age, so we're just following orders. QUOTE(mylife4nerzhul @ Jun 25 2009, 07:34 AM) Q: How'd they get all the ice in a bottled water through that little tiny hole? by freezing it after the water is in the bottle ? |
