Does anyone else find it suspicious that the universe is supposed to
be just about exactly half as old as it is across (in light years)? I
don't know that much
about physics, (I'm sure you never would have guessed), but it
seems funny to me to suppose that the
beginning of the universe is
just as far back in time as the time it
would have taken the light to cross the distance to get here, so I'm
proposing a new universe where the "beginning" is just a fading
out effect of not being able to see that far.

This simply confirms my long-held suspicion that I am the center of the universe. |
|
| |
Ah, you're a Cambridge graduate, then? |
|
| |
I believe it's from wearing that damn Asteroid Belt! |

As you look outwards into the Universe, you also look backwards in time, because light takes time to travel. |
|
| |
Any ray projected outwards from the Earth can also be considered to be projected backwards in time; all such rays (that don't hit another star, galaxy, etc on the way) eventually encounter the Big Bang, which can be seen as being 13.7 billion years ago, 13.7 billion light-years away, or any combination of the two. |

A few years ago I saw a brilliant diagram which explained this superbly; unfortunately I can't find it now. |

Are you soliciting for donations? Or looking for advice on where to source components? |
|
| |
We ain't finished with the old one yet. |
|
| |
According to NASA, the "known universe" (not necessarily the entire universe) is 94 billion light years in diameter due to expansion after the light started traveling. See link. Where are people getting the numbers for a 13.7B light-year radius? |

//Where are people getting the numbers for a 13.7B
light-year radius?// That's the size for Universe Lite,
which has some features disabled but is much
cheaper than the full version. |

No good asking me. I am a member of the Flat Universe Society. Willing to participate in any big bang though. |

The phenomena you observe is analogous to
observing the horizon, which keeps going further out
as you go higher, but at some point, you see the
curvature of the planet. |

What you need is a really tall 4 dimensional tower. |
