English to Arabic Other Religion

here is the context:

Atheism, Darwinism, and virtually all the "isms" emanating from the eighteenth to the twentieth century philosophies are built upon the assumption, the incorrect assumption, that the universe is infinite. The singularity has brought us face to face with the cause – or causer – beyond/behind/before the universe and all that it contains, including life itself.

can I translate singularity as تفرد

what about " the universe is infinite" , Can I say " العالم لا نهائي" ?
