Well now that would depend on what Deus ex Machina revealed...If it simply revealed that it created life and set in motions the principles of its variations, mutations, adaptations and extinctions of various sub groups it doen't destroy mathematics nor sets at naught the three sided triangle. Salt remains salt...and A will still = C if A=B and B=C. 1+1 will still =2 and what objects that exist can never again be said to have not existed. Evolution may be scientifically strengthened or set at naught, but if set at nought the basic fundamentals of reason and logic will remain firm and strong. Yes and vinegar and Bicarb will still fizzle when mixed!
The fundamentals don't change unless Deus Ex Machina should declare it so...
Now Science can't speak to Deus ex Machina as this is tautologous in concept and can't de demonstrated or falsified...I undestand this.
It can be said truthfully that our universe such as it is will continue in its current state tending towards randomness and disorder unless an out side force should act upon it to change it.
Science can make no predictions FOR THE EXISTENCE of Transcendent applied activity upon the Universe nor should proper scientists make BIASED PREDICTIONS AGAINST SUCH ACTIVITY!(that is and still stay true to science)
"The fundamentals don't change unless Deus Ex Machina should declare it so... "
Unless of course Monsieur Deus Ex Machina doesn't bother to inform us of the change.
