Jewish Science 101
The Bible and Talmud saw science and the Jewish tradition as manifestations of the same divine truth. The rabbis of the Talmud even used science in legal decision making-- using astronomical calculations to create the Jewish calendar--and referenced many of the scientific theories of their time.
Medieval Jewish thinkers--many of them scientists—were forced to struggle with new scientific theories and apparent contradictions between Judaism and science. Maimonides strove to integrate Judaism and science, going so far as to assert that if the eternity of the universe was proven though science he would reinterpret the biblical passages figuratively bring them in line with scientific truth.
The scientific theory of evolution seems to contradict the biblical account of creation. While the Bible claims that God created the world in six days, culminating with the creation of humanity, the theory of evolution asserts that humanity evolved over billions of years.
Some Jews reject evolutionary theory, while others reject the biblical account of creation. Many, however, strive to integrate the biblical account with the findings of modern science. Some Jewish thinkers reconcile the biblical account of creation with evolutionary theory by rejecting literal understandings of the Bible in favor of metaphorical or allegorical readings. Recent theories regarding the expansion of the universe have provided new opportunities for reconciling the biblical account of creation with science.
Some modern kabbalists have looked to the scientific theory of exponential expansion for corroboration of Lurianic kabbalistic ideas. These thinkers suggest that tzimtzum (God's withdrawal from the universe) occurred during the moments right before creation, when, according to the theory of eternal inflation, the universe began to expand exponentially, inflating countless random quantum events in the process.
