We only see shadows of reality. We shouldn't expect those shadows to behave sensibly. - Lawrence M. Krauss

Now, since the time of Newton there had been a debate about whether light was a wave---that is, a traveling disturbance in some background medium---or a particle, which travels regardless of the presence of a background medium. The observation of Maxwell that electromagnetic waves must exist and that their speed was identical to that of light ended the debate: light was an electromagnetic wave.

A universe without purpose should neither depress us nor suggest that our lives are purposeless. Through an awe-inspiring cosmic history we find ourselves on this remote planet in a remote corner of the universe, endowed with intelligence and self-awareness. We should not despair, but should humbly rejoice in making the most of these gifts, and celebrate our brief moment in the sun.

I don’t make any claims to answer any questions that science cannot answer, and I have tried very carefully within the text to define what I mean by “nothing” and “something.” If those definitions differ from those you would like to adopt, so be it. Write your own book. But don’t discount the remarkable human adventure that is modern science because it doesn’t console you.
