but back on topic, what else can u expect from those nerds at harvard.... BUT it is preatty cool |
None taken, it's somewhat related to my studies at school. I just wanted to set the record straight. =)
I have a tendency to say too much though.
I agree, it is quite cool though. Materials research is a very quickly growing field at the moment. |

| Light is truly an amazing phenomenon, and much about it is still a mystery. Do we even know what the light is exactly (exept photons)? |

BUMP
Cool stuff if you haven't seen it yet. |

| This has also been done by runing light through certain stones, i forget which ones tho. IT was posted here a while back |

omg!!! you lucky bastards... rush hour traffic here in norway is usually about 10-15 kmph... (10 mph) |

Light or the c in E=mc² is supposed to be a constant in that equation. If light is either stopped or slowed down it isn't a constant anymore.
A simple explanation I hope: In order for someone to travel at or near the speed of light he has to be lighter in weight/mass than light itself. But since light can be stopped or slowed the equation does not work. Kind of like changing pi from 3.14 to 1.1 to 5.32 to 124.4 everytime you had to figure the circumference of a circle.
Since the measure of starlight would be affected by the extreme coldness of space, it would also kill the "Big Bang" theory. |

:o
Please elaborate. |

In order to slow down or stop light they had to simulate space. Or better yet outdo it's temperature. If they have to simulate space then space itself is at or near absolute zero (0º Kelvin). If space is at or near absolute zero (0º Kelvin) then light is stopped or slowed. And if light is stopped or slowed there can never be an "expanding/collapsing universe" based on the "Big Bang" theory.
The average temperature of space, from what I've gathered so far, is 2º to 15º K. This would be in space where there would be no stars or nebula nearby.
The coldest temperature that anything can realistically reach is 3 K. This is the temperature of the cosmic microwave background radiation (CMB)[click]. |
