Primary 5 maths question goes viral, stumps adults SINGAPORE - A Primary school mathematics question has been making the rounds on Facebook and stirring up debate.

The line of reasoning often attributed to Fermi, in his lunchtime conversation, runs like this: There may be many habitable Earth-like planets in our Milky Way galaxy. If intelligent life and technological civilization arise on any one of them, that civilization will eventually invent a means of interstellar travel. It will colonize nearby stellar systems. These colonies will send out their own colonizing expeditions, and the process will continue inevitably until every habitable planet in the galaxy has been reached.

The fact that there aren’t already aliens here on Earth was therefore supposed to be strong evidence that they don’t exist anywhere in the galaxy. This argument actually isn’t Fermi’s and was published more than 25 years later by astronomer Michael Hart. It was elaborated in a paper published by the cosmologist Frank Tipler in 1980.

Beyond "Fermi's Paradox" I: A Lunchtime Conversation- Enrico Fermi and Extraterrestrial Intelligence It’s become a kind of legend, like Newton and the apple or George Washington and the cherry tree. One day in 1950, the great physicist Enrico Fermi sat down to lunch with colleagues at the Fuller L...

Professor Hawking devised an ingeniously simple experiment to prove whether time travel to the past was possible. He held a reception for time travelers, but didn't publicize it until after it had happened. This way, only those who could travel back in time would be able to attend. — feeling thoughtful.
