Quotes About Space

It shouldn't be so difficult to determine what a planet is. When you're watching a science fiction show like 'Star Trek' and they show up at some object in space and turn on the viewfinder, the audience and the people in the show know immediately whether it's a planet or a star or a comet or an asteroid.

I've been enthralled by deep vistas of space and time ever since watching George Pal's film of 'The Time Machine,' while an early encounter with Arthur C. Clarke's 'The City And The Stars' cemented my love for books with a scope spanning millions of years.

It hadn't really percolated through my brain that I was going to see real, live TV from the surface of the Moon, and boy, oh, boy, had that Saturn V launch been exciting! And then, there it was - late at night, sitting up, watching, and there was Neil Armstrong actually standing on the surface of the Moon.

I grew up watching a lot of the coverage of the early U.S. space program, all the way back starting with Mercury and then through Gemini and Apollo and of course going to the moon as the main part of the Apollo program.

I'm 9, 10, and I'm watching the Apollo astronauts go to the moon. We're sitting on the floor of a school, and they have this... huge TV, and I'm looking at that, and I'm thinking 'Me, I would like to do that.' But it didn't dawn on me then that they were American; I was Canadian. They were men; I was a girl. They were test pilots, military folks.

The competitive landscape for us is very broad. We see ourselves in the entertainment space. We compete with listening to the radio. We compete with watching TV. We compete with social networks.

As a young planet, Venus was losing hydrogen rapidly to space. The oceans boiled off, and after some period of time, perhaps 600 million years, there was no surface water.

To an observer situated on the moon or on one of the planets, the most noticeable feature on the surface of our globe would no doubt be the large areas covered by oceanic water. The sunlit face of the earth would appear to shine by the light diffused back into space from the land and water-covered areas.

It's an electrical network, isn't it? It's molecules in space... and they're linked to each other electrically. Which is to say, one end of a soap molecule is attracted to a nearby water molecule electrically. The bubble is this network. The whole thing is inter-dependent.

There was a lake beneath me, but the big, heavy parachute which had to be opened two miles above the ground couldn't be steered. My first thought was, 'Lord, they send just one woman into space, and she has to end up in the water.'

Gravity pulls our bodily fluids down, like water in a glass goes to the bottom part of a glass. In space, the water doesn't stay in the bottom of the glass. It distributes itself evenly over time throughout the entire volume of the glass.

Geo-stationary orbit is actually real estate - you can only put so many satellites up there. It's like waterfront property at the beach. Everyone builds the biggest thing they can put up there.

There is hopeful symbolism in the fact that flags do not wave in a vacuum.

I thought that there must be an easier way to explain how a gravitational wave interacts with matter: If one just looked at the most primitive thing of all, 3D floating masses out in space, and look at how the space between them changed because of the gravitational wave coming between them.

The obvious thing to me was, let's take freely floating masses in space and measure the time it takes light to travel between them. The presence of a gravitational wave would change that time. Using the time difference, one could measure the amplitude of the wave.

I think it quite likely that we are the only civilization within several hundred light years; otherwise we would have heard radio waves.

When gravitational waves reach the earth, the waves stretch and squeeze space. This is a tiny stretch and squeeze. Far too small to detect with ordinary human senses.

You know the Einstein waves can be thought of as a distortion of space and time. But the way we see it, we see it as a distortion of space. And space is enormously stiff. You can't squish it; you can't change its dimensions so easily.

Space is much stiffer than you imagine; it's stiffer than a gigantic piece of iron. That's why it's taken so damned long to detect gravitational waves: to deform space takes an enormous amount of energy, and there are only so many things that have enough.

Since my own genome was sequenced, my software has been broadcast into space in the form of electromagnetic waves, carrying my genetic information far beyond Earth. Whether there is any creature out there capable of making sense of the instructions in my genome, well, that's another question.

Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the drug store, but that's just peanuts to space.

I believe that the way people live can be directed a little by architecture.

Once you get into space, you can really unleash a lot of creativity, but the launch itself? I have been through all of the creative ways, and believe me, chemical rockets are the best.

It was Apollo 8 that first showed us the tiny blue marble of Earth floating in the void of space, one of the great psychological shifts in human history. From out there, we can both appreciate and begin to solve the problems of our world in ways unavailable to us otherwise.
