Light has no mass. Absolutely zero.
Yet it bends around stars, warps near galaxies, and spirals into black holes.
How can gravity pull on something with nothing to pull?
But gravity isn't pulling at all.
In this mind-bending physics documentary, we explore one of Einstein's most profound revelations - and discover why everything you thought about gravity is wrong.
In this deep-dive documentary, we go deep:
→ The 1919 solar eclipse that proved Einstein right and made him a global icon overnight
→ Why Newton's gravity couldn't explain the full 1.75 arcsecond deflection of starlight
→ How a 6.2 billion light-year distant star was magnified 1000x by gravitational lensing
→ The forgotten scientists - Michell, Laplace, Soldner - who predicted light-bending before Einstein
→ Why light follows geodesics through curved spacetime at 186,000 miles per second
