  1. John Wheeler

  2. Albert Einstein

  3. Hermann Minkowski

  4. Ludwig Boltzmann
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

John Wheeler, an American physicist, proposed the idea of 'spacetime foam', a hypothetical structure at the smallest scales of space and time. This concept suggests that spacetime is not smooth but rather has a frothy, quantum nature.
