What we still don't know!

Welcome to the frontier of knowledge!

As this section of Tell Me How contains hundreds and hundreds of answers to question, to balance things up here is a list of questions to which we still don't know the answer, and may never know.

If you would like to contribute any others, please contact us here

  • What is dark energy?
  • What is dark matter?
  • Why was more matter than anti-matter created at the birth of the universe?
  • Has there been more than one Big Bang?
  • Is there intelligent life elsewhere in the universe (are we alone)?
  • Is the universe unique or part of a 'multiverse'?
  • Is time travel (to the past) possible?
  • Would the concept of self still exist if we could replicate (e.g. transport)?
