Re: How far can we see?

don`t forget that at the very start the Universe was expanding faster than light (universes are allowed to do this, its things inside em that can`t go FTL), so a HUGE chunk of the Universe is so far away that we can`t see it and never could, even with a "SuperHubble", the chunk we CAN see is comparable in size (so I read once) to about the size of a grain of sand in the Superbowl stadium.

I`m from England so I don`t actually know how big the Superbowl stadium is, but assuming it`s bigger than a football stadium, thats one BIG universe, you just need some advanced technology to get to it, like a wormhole generator or a quantum transporter of some sort, since it`s recession velocity is still faster than light (and still accelerating by recent accounts) , so going via normal space won`t cut it.

afaik the current furthest object has a recession velocity of 0.84C, so thats over 4/5ths of the way back to creation (and IF the Universes expansion IS still accelerating then that object got beyond our reachable range a LONG time ago and is now (from our viewpoint) traveling faster than light.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.
