Join us for live screenings of The Royal Institution 2026 CHRISTMAS LECTURES®.

We’re delighted to announce we are one of the livestream venues for this year’s CHRISTMAS LECTURES® from the Royal Institution. 

Running for 200 years, the CHRISTMAS LECTURES® were started by Michael Faraday to inspire and engage young people with science. This year leading space scientist, physicist, broadcaster and author, Professor Jim Al-Khalili, will tackle the awe-inspiring science of time.

Lectures theme: About Time 

In the 2026 Royal Institution CHRISTMAS LECTURES® theoretical physicist Jim Al-Khalili will investigate what time actually is and why it remains one of science’s most tantalising mysteries. 

Across three lectures, Jim will tackle the awe-inspiring physics of time, investigating a series of mind-melting questions:

  • Does time have a direction?
  • Have humans already time travelled?
  • Is the future all mapped out?
  • Did time exist before the Big Bang?
  • Does time even exist at all?
  • And why are our heads aging faster than our feet?!

Only time (and Jim) will tell…

Lecture episodes

Please note we are only showing two of the three lectures. 

Episode 1 - What Is Time?

Jim swings from the roof of the Royal Institution’s iconic Theatre and smashes crystals as he explores the curious ways we measure time. He'll test whether our brains are good timekeepers and uncover the truth that time may not actually be constant throughout the universe! 

Episode 2 - When Is Now?

Jim breaks down why the idea of “now” has wracked the brains of scientists and philosophers for thousands of years. It’s a maddening contradiction that as soon as we try to grasp the present moment it slips into the past. Jim believes it could lead us to a deeper truth buried in the universe, a hidden arrow of time pointing from the big bang to the cosmic crunch.
