Science is the single most productive means humanity has ever come across for gaining useful information about the physical universe.
Science is based upon the systematic gathering of data on measurable and replicable natural phenomena, and attempts to explain and predict these data by appeal to measurable and replicable natural causes in the formation of a scientific hypothesis.
If the evidence supports the hypothesis, and your hypothesis is found to be USEFUL in predicting and explaining natural phenomena, then it may one day be regarded as a theory.
A theory is the highest rank of scientific explanation, making the construction “just a theory” the domain of tools and fools.
Nice, and I guess everyone is to ignore multiverse theory, string theory, the fact that scientists study the effects of prayer...
what a hoot!
And what are the findings of those studies?
Do you think somehow that the sciences of geology or biology or chemistry or physics are somehow changed or discredited because some theoretical physicist published some musings about the “multi-verse”?
If it is a productive hypothesis it will be embraced and expounded upon.
If it is not productive they will wonder “what was he smoking”.
That is how science works. We have a mechanism for sorting out the productive ideas from the useless ones.
