Science makes god unnecessary.
What is important is that we have the ability to create.
Nuclear weapons need large facilities, but genetic engineering can be done in a small lab. You can’t regulate every lab in the world. The danger is that either by accident or design, we create a virus that destroys us.
There could be whole antiworlds and antipeople made out of antiparticles. However, if you ever meet your antiself, don’t shake hands! You would both vanish in a great flash of light.
If human life were long enough to find the ultimate theory, everything would have been solved by previous generations. Nothing would be left to be discovered.

Religion believes in miracles, but these aren’t compatible with science.
I don’t have much positive to say about motor neuron disease, but it taught me not to pity myself because others were worse off, and to get on with what I still could do. I’m happier now than before I developed the condition.
In effect, we have redefined the task of science to be the discovery of laws that will enable us to predict events up to the limits set by the uncertainty principle.
I’m here to chew gum and kick some ass, and I’m all out of gum.

Time travel was once considered scientific heresy, and I used to avoid talking about it for fear of being labelled a ‘crank.’
Many people find the universe confusing – it’s not.
There is nothing bigger or older than the universe.
There is a real danger that computers will develop intelligence and take over.
Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it.
We’ve created life in our own image.
We explore because we are human.
