If nothing is “objectively real” prior to “measurement”, what exactly is a “measurement”? +1, god damn good question |

What is the current radius of cosmological event horizon? @Johannes : I am not looking for changes of cosmological event horizon in time, but that right now given that $H_0$ is constant in space, then what is the value of cosmological event horizon right now? |

What is the current radius of cosmological event horizon? @LubošMotl : because of the first line of the answer , I wasn't sure if my question was implying the contrary, I wasn't questioning Johannes but confirming that my question is not implying the contrary. the result I ended up with was $13\times10^{10}$ it is 3 times the answer of from alpha. My question is at this point of time, how far is the cosmological event horizon? If it was possible to take a snap shot of universe, with given $H_0$ at this point of time, since it is not dependent on time. |

What is the current radius of cosmological event horizon? Is The Hubble length suppose to coincide with the radius of the observable universe? or not? Sorry I am confused, I don't know why Hubble length and radius of the observable universe relate to each other. |

Will a magnet loose too much strength it cut with a hacksaw? If heat is a concern, then liquid nitrogen will make it a snap! |

Variations of double slit experiment with their results to look up Indeed that is type of thing that I am intrested, time to spice up the double slit experiment! |

From where (in space-time) does Hawking radiation originate? @Dilaton : I thought the radiation was due to the uncertainty principle. |

From where (in space-time) does Hawking radiation originate? @Dilaton : yes, but is it an exact distance or has some level indeterminency? in other words could a photon inside finds itself (if it is sufficeintly close enough to some region we would consider as the event horizon) all of a sudden outside? |
