Could a huge lunar telescope be our best chance of spotting aliens?

In this latest instalment of Future Chronicles, an imagined history of future inventions, Rowan Hooper explores the advances that meant an optical telescope with an effective mirror size of 3000 km could be built on the moon

2H2KWEA Big Bang to Present. Stages in the history of the Universe after the Big Bang. At 300, 000 years, matter and radiation decouple, and the Universe becomes transparent for the first time. The first galaxies form at around 300 million years after the Big Bang, but the exact time period is uncertain. At an age of 9 billion years the Solar System formed. Finally, 13.7 billion years after the Big Bang we arrive at the present day. The Universe is still expanding and evolving.
