Beyond Einstein: Gravity, Time and the Edge of Knowledge – with Prof. David F. Mota (Condensed)

95% of the universe is made of something we can’t see and don’t understand. We call it dark matter and dark energy – or, as cosmologist David F. Mota puts it, “a name for our ignorance.”

In this condensed edition of my conversation with Professor David F. Mota from the Institute of Theoretical Astrophysics at the University of Oslo, we go beyond Einstein:

• How gravitational waves let us hear the universe for the first time
• The 2017 cosmic collision that wiped out a whole family of gravity theories
• Why the cosmological constant might just be duct tape
• What time actually is – and why nobody knows
• How the Euclid space telescope could reveal whether dark energy changes over time

Recorded in 2025 and cut down to the core – the big questions are as open as ever. Euclid’s first major data release is arriving now, with cosmology results expected in 2027. When they land, David will be back.
