GeekSpeak – Is there a civilization around Tabby’s Star? Join the discussion on Saturday April 1 at 12pm SLT


There are rumors that there may be alien megastructures around Tabby’s Star, which is about 1500 light years from Earth.  Other explanations have been suggested for the variation in the light from the star but none of them fit all the data.  So it is possible that a Kardashev type 2 civilization is ruling over that area of space.

The Kardashev scale measures how much energy is used.  Type 1 uses the energy of the home planet, Type 2 the energy of the solar system, Type 3 the energy of the galaxy.  To build huge structures around stars a Type 2 would be needed.

How would these cultures work?  How do they build such huge structures and why?  Will we ever be able to send messages to them?  Do they know about us?  Should we be scared?

Join us at GeekSpeak on Saturday at noon SLT to talk about Tabby’s star.  Bring all your alien friends!
