Reliability Big Bang

March 26, 2014

Commenting on the excellent:

I guess I will have to get more subtle with my own “Universe: 100-billion years old?” (Hahaha) Yet “BICEP2 can really only tell us about the late stage and exit from inflation”.

In any case, thank you for this detailed analysis on how certain we are of the various elements of the concept of Big Bang. This is the sort of subtlety that needs to be taught to the public: that there are degrees of certainty in science. And even on physics.

By preaching the Big Bang as if it were a religion, as many scientists have done in popular shows (latest on “Cosmos”, complete with multiverse, presented as part of our “address”!) one did a disservice to science, or even to reason itself… And there could be a backlash, if the public discovers that they were lied to. So the earlier the subtleties are taught, the better.
