Physics finds no trace of God so far—but does it matter?
Can God exist out there in space-time? Do the laws of nature support the idea of a divine creator, or do they rule it out? At the moment, the existence of a god is a deep question for theologists and philosophers: it won't become a scientific question until there is evidence of God. With so much uncertainty, the question Bill Nye likes to focus on instead is: how would that knowledge change your life? Is who you are, with and without religion, two different versions of your self? The reality is that you don't need evidence of any god to live a good life. For Nye personally, he goes by the moral framework of "be responsible for my own actions, and leave the world better than I found it." That's probably the surest way to protect the life of the people and the earth that we have, whether or not it was made by higher power.
Get ready for a decade of scientific revelations. Thanks to gravity waves, we have a completely new way to explore the universe.
Alex Filippenko is a Hertz Foundation Fellow and recipient of the prestigious Hertz Foundation Grant for graduate study in the applications of the physical, biological and engineering sciences. When the discovery of gravitational waves was announced in February 2016, Filippenko was awed. The researchers at LIGO (Laser Interferometer Gravitational-Wave Observatory) managed to prove a key prediction of Einstein's general theory of relativity: his theory of gravity. Here, Filippenko explains the mind-boggling way they did it, and the scope of discoveries that this hyper-precise technology will reveal to us over the next decade. With the support of the Fannie and John Hertz Foundation, Filippenko pursued a PhD in astronomy at the California Institute of Technology.
