The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?

All that my work has shown is that you don't have to say that the way the universe began was the personal whim of God.

If I have questions about the universe on my mind when I go to bed, I can't turn off. I dream equations all night.

While there's life, there is hope.

The universe and the Laws of Physics seem to have been specifically designed for us. If any one of about 40 physical qualities had more than slightly different values, life as we know it could not exist: Either atoms would not be stable, or they wouldn't combine into molecules, or the stars wouldn't form heavier elements, or the universe would collapse before life could develop, and so on...

It is impossible to imagine a four-dimensional space. I personally find it hard enough to visualize a three-dimensional space!

The doctor who diagnosed me with ALS, or motor neuron disease, told me that it would kill me in two or three years.
