Fritz Zwicky Quotes

When someone tells me, 'Oh, we have so many problems on Earth; space exploration costs too much money,' I say, 'I absolutely agree with you. But I still hope we do it.'

If we want to implement climate protection worldwide, countries like Germany, which are capable of developing new technologies, will have to hand over some of their knowledge. We can't expect to have our cake and eat it too.

I feel we must all exert ourselves to the utmost to see that the ideals and hopes held by Alfred Nobel, whom we commemorate today, do not fail from lack of purpose on the part of scientists.

Space exploration is a force of nature unto itself that no other force in society can rival.

People need to be made conscious of a very simple reality: we have no choice but to share this planet, this small blue sphere floating in the vast reaches of space, with all of our fellow 'passengers.'

The International Space Station is a phenomenal laboratory, an unparalleled test bed for new invention and discovery. Yet I often thought, while silently gazing out the window at Earth, that the actual legacy of humanity's attempts to step into space will be a better understanding of our current planet and how to take care of it.

Mining asteroids will ultimately benefit humanity on and off the Earth in a multitude of ways.

This is the only global scale catastrophe that we know how to prevent, and for the cost of building a highway overpass.

We have brought down emissions in this country through our legal system and through technological innovation. We can do this on our own. We don't have to have the permission of countries all over the world to do that.

We have one planet in our solar system that's habitable, and that's the Earth, and space travel can transform things back here for the better. First of all, by just having people go to space and look back on this fragile planet we live on. People have come back transformed and have done fantastic things.

My personal opinion, Suni Williams - I think that when we really leave the planet - we all go as humans, not as people from one country or another. We are humans; we work together. This is our only planet as human beings that we know of. So we all should have an interest in preserving it.

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.

The earth, the sea and air are the concern of every nation. And science, technology, and education can be the ally of every nation.

I don't want students who could make the next major breakthrough in renewable energy sources or space travel to have been taught that anything they don't understand, and that nobody yet understands, is divinely constructed and therefore beyond their intellectual capacity. The day that happens, Americans will just sit in awe of what we don't understand, while we watch the rest of the world boldly go where no mortal has gone before.

Science has given to this generation the means of unlimited disaster or of unlimited progress. There will remain the greater task of directing knowledge lastingly towards the purpose of peace and human good.

We're not sane enough yet to enter space until we learn to live together in peace on Earth.

Today, more than ever before, science holds the key to our survival as a planet and our security and prosperity as a nation. It's time we once again put science at the top of our agenda and work to restore America's place as the world leader in science and technology.

Maybe we have enough technology to save the planet but it is not enough because the people are not ready.

Science and Peace will triumph over Ignorance and War...

If I could get one message to you it would be this: the future of this country and the welfare of the free world depends upon our success in space. There is no room in this country for any but a fully cooperative, urgently motivated all-out effort toward space leadership. No one person, no one company, no one government agency, has a monopoly on the competence, the missions, or the requirements for the space program.

I realized up there that our planet is not infinite. It's fragile. That may not be obvious to a lot of folks, and it's tough that people are fighting each other here on Earth instead of trying to get together and live on this planet. We look pretty vulnerable in the darkness of space.

Around the world, we see the results of exploitation which destroys much without taking future generations into account. Protecting the world's forests; stemming desertification and erosion; avoiding the spread of toxic substances harmful to man, animals and plants; protecting the atmosphere; all these can be accomplished only through active and wise cooperation, without borders or political power plays.

Let us take advantage of the opportunities presented by climate action and lay the foundations for a more prosperous and secure future for all

But while I'm realistic about our challenges, I'm optimistic about our future. There are a few things, and if we do them, we're going to have the greatest era in our history. And I have detailed what those things are specifically.

If NASA were advancing a space frontier there would be challenges you've never seen before. You have to be creative and you have to patent some new idea. You get to Mars...well, how do we get the water from the soil? I gotta invent a new device that will do that. And the carbon dioxide in the atmosphere, how can we use that? Can we breathe the oxygen from the carbon dioxide?
