Even if it turns out that time travel is impossible, it is important that we understand why it is impossible.Stephen Hawking
There are grounds for cautious optimism that we may now be near the end ofthe search for the ultimate laws of nature.Stephen Hawking
Time travel was once considered scientific heresy, and I used to avoid talking about it for fear of being labelled a 'crank.'Stephen Hawking
Look up at the stars and not down at your feet. Try to make sense of what you see, and wonder about what makes the universe exist. Be curious.Stephen Hawking
I believe alien life is quite common in the universe, although intelligent life is less so. Some say it has yet to appear on planet Earth.Stephen Hawking
I was born on January 8, 1942, exactly three hundred years after the death of Galileo. I estimate, however, that about two hundred thousand other babies were also born that day. I don't know whether any of them was later interested in astronomy.Stephen Hawking
Not only does God play dice, but... he sometimes throws them where they cannot be seen.Stephen Hawking
The radiation left over from the Big Bang is the same as that in your microwave oven but very much less powerful. It would heat your pizza only to minus 271.3*C - not much good for defrosting the pizza, let alone cooking it.Stephen Hawking
It's time to commit to finding the answer, to search for life beyond Earth. Mankind has a deep need to explore, to learn, to know. We also happen to be sociable creatures. It is important for us to know if we are alone in the dark.Stephen Hawking
It was Einstein's dream to discover the grand design of the universe, a single theory that explains everything. However, physicists in Einstein's day hadn't made enough progress in understanding the forces of nature for that to be a realistic goal.Stephen Hawking
