Spacetime: continuous or quantized?

  1. Apr 12, 2012 #1
    What proof or evidence -both theoretical or emperical - is there, that spacetime is quantized or continuous?

    There is no experimental evidence for either. Continuous is assumed for General Relativity. Quantum theory is inadequate. Extensions that try to unite these theories seem to lean toward quantized.
