Speed of light...instantatious Travel??

Comment: Division by zero doesn't necessarily give you an error. If you take lim(x->0)+ [1/x] you'll get infinity, which is an acceptable mathematical answer. lim(x->0)- [1/x] gives you negative infinity. It's not an error, per se, but more an indeterminable state, unless the limit is defined.

But, as you said tormod, this doesn't have practical applications.

Quick question: If travel at the speed of light necessitates a passage of time somewhere, does travel through a wormhole do likewise? Since light speed is thought to be the "barrier" for all speed possible, then travelling through a wormhole would be instantaneous and circumvent this speed limit. So would the universe compensate by forwarding (or reversing?) time elsewhere?

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.
