Firstly, just to bang my usual drum on this

, it is a myth that Einstein's idea were initially ignored. They were taken up with great alacrity. He was appointed associate professor at Zurich in 1909, only 4 years after his
Annus Mirabilis papers were published. Sure, his findings were disputed or challenged by a proportion of physicists for a number of years, as was to be expected in view of their revolutionary nature. But they were far from being met with the indifference shown towards Tegmark's ideas. They immediately set the cat among the pigeons.
Secondly, the indifference towards Tegmark is most likely in large part because his ideas about a "mathematical universe" are not science. They are just a metaphysical speculation, with no observable consequences and as such untestable. Like Bohm's pilot waves they are, as Pauli puts it, an "uncashable cheque".
