Yahoo! News - Universe Measured: We're 156 Billion Light-years Wide!

I love this tidbit of information. Stated with so much assurance and so much room for error. And I love this quote.
Yahoo! News - Universe Measured: We're 156 Billion Light-years Wide!: "'If the universe was finite, and had a size of about 4 billion to 5 billion light-years, then light would be able to wrap around the universe, and with a big enough telescope we could view the Earth just after it solidified and when the first life formed,' Cornish said. 'Unfortunately, our results rule out this tantalizing possibility.'"
