“Nature does not know extinction; all it knows is transformation. Everything science has taught me-and continues to teach me-strengthens my belief in the continuity of our spiritual existence after death. Nothing disappears without a trace.”

I believe in an immortal soul. Science has proved that nothing disintegrates into nothingness. Life and soul, therefore, cannot disintegrate into nothingness, and so are immortal.

The greatest gain from space travel consists in the extension of our knowledge. In a hundred years this newly won knowledge will pay huge and unexpected dividends.

If we were to start today on an organized and well-supported space program I believe a practical passenger rocket can be built and tested within ten years.

I’m convinced that before the year 2000 is over, the first child will have been born on the moon.

I believe that the time has arrived for medical investigation of the problems of manned rocket flight, for it will not be the engineering problems but rather the limits of the human frame that will make the final decision as to whether manned space flight will eventually become a reality.

With our present knowledge, we can respond to the challenge of stellar space flight solely with intellectual concepts and purely hypothetical analysis. Hardware solutions are still entirely beyond our reach and far, far away.

My friends they were dancing here in the streets of Huntsville when our first satellite orbited the Earth. They were dancing again when the first Americans landed on the Moon. I’d like to ask you, don’t hang up your dancing slippers.

I only hope that we shall not wait to adopt the program until after our astronomers have reported a new and unsuspected asteroid moving across their fields of vision with menacing speed. At that point it will be too late!

One good test is worth a thousand expert opinions.

By the year 2000 we will undoubtedly have a sizable operation on the Moon, we will have achieved a manned Mars landing and it’s entirely possible we will have flown with men to the outer planets.

If we continue at this leisurly pace, we will have to pass Russian customs when we land on the moon.

Basic research is what I am doing when I don’t know what I am doing.

Conquering the universe one has to solve two problems: gravity and red tape. We could have mastered gravity.

The rocket worked perfectly, except for landing on the wrong planet.

Our sun is one of a 100 billion stars in our galaxy. Our galaxy is one of billions of galaxies populating the universe. It would be the height of presumption to think that we are the only living thing in that enormous immensity.

A good engineer gets stale very fast if he doesn’t keep his hands dirty.

I believe acting truly is harnessing the power of belief.

Religion is the belief in future life and in God. I don’t believe in either.

Belief in God is almost universal and the effect of this belief is so vast that one is appalled at the thought of what social conditions would be if reverence for God were erased from every heart.

I know Jesus is not finished with me yet.

We never stop to consider that our beliefs are only a relative truth that’s always going to be distorted by all the knowledge we have stored in our memory.

The body, like everything else in life, is a mirror of our inner thoughts and beliefs. Every cell within your body responds to every single thought you think and every word you speak.

My love, I challenge you to liberate your destiny and free your dreams from your limiting belief.

There is little sense in attempting to change external conditions, you must first change inner beliefs, then outer conditions will change accordingly.
