Science

How Did the Universe Begin?

Professor Barth Netterfield’s lifelong journey into faith, physics and astronomy

September 23, 2017 | By Barth Netterfield

I come from two worlds. One is the world of science. The other is the world of faith.

As a child, I felt the presence of God all around me. In stars. In trees. In insects.

...the more impressive they become.

At the same time, I was fascinated by where things came from and how they worked.

Not long before he died, my 91-year-old grandfather encouraged me to study science. He didn't accept all of its findings, but he believed in the process.

I enrolled at a Christian liberal arts college in Minnesota, where I studied physics - and religion.

At grad school, a friend and I often didn't see eye to eye on religion.

Now as an astronomer I use huge balloons to raise telescopes 35km above the Earth - to avoid the atmosphere and get a clear view of deep space.

In one experiment, we studied the cosmic microwave background - the faint afterglow of the Big Bang.

But nothing we or anyone else has discovered explains why the universe exists, or what purpose it serves.

And, as I tell my students, there's still so much we don't know. We've observed that the expansion of the universe is accelerating. But we have no idea why. It's as if empty space has hidden energy. This is what we call dark energy.

We don't know what happened in the first moments of the universe. And we don't know if our universe is one of many.

What we do know is that, compared to the age of the universe, all of human history is but a moment.

...and the Milky Way is just one of hundreds of billions of galaxies. As we look deeper and deeper into the universe, peering back to the beginning of time... the more mysterious and breathtaking it becomes...

...revealing, to my eyes, on an ever-grander scale, the creative majesty of God.
