A Quote by Seth Shostak

Give consideration to the fact that alien astronomers could have scrutinized Earth for more than 4 billion years without detecting any radio signals, despite the fact that our world is the poster child for habitability.

Almost any biographer, if he respects facts, can give us much more than another fact to add to our collection. He can give us the creative fact; the fertile fact; the fact that suggests and engenders.

Virginia Woolf

Radio astronomers study radio waves from space using sensitive antennas and receivers, which give them precise information about what an astronomical object is and where it is in our night sky. And just like the signals that we send and receive here on Earth, we can convert these transmissions into sound using simple analog techniques.

Honor Harger

Ever since the Second World War, television signals (as well as FM radio and radar) have served as Homo sapiens' emissaries into deep space. High-frequency, high-power broadcasts have filled an Earth-centered bubble more than 60 light-years in radius with signals.

Despite the fact that he no longer dressed like the big dork he did then, despite the fact that he’d swapped the nerd wear for some much cooler clothes, despite the fact that he’d let his hair go all shaggy and loose to the point where it curved down into his face in that cool guy, slightly windswept, effortless way, despite the fact that every time I looked into his brilliant blue eyes I was totally reminded of the Zac Efron poster that used to hang on my old bedroom wall, it still didn’t make it okay for him to laugh at me the way he did.

I don't think there has been any mayor in America scrutinized that way. I don't think there has been any mayor as a matter of fact, Coleman Young I think received an incredible amount of scrutiny and he was kind of the poster child for that in Detroit. He was the first Black mayor who really expressed his manhood in a different way than had been seen from African-American man that was projected across the country.

Kwame Kilpatrick

I can remember the time when, if we wanted a house or housing, we relied on private enterprise. In fact, Americans built more square feet of housing per person than any other country on the face of the earth. Despite that remarkable accomplishment, more and more people are coming to believe that the only way we can have adequate housing is to use government to take the earnings from some and give these earnings, in the form of housing, to others.

Leonard Read

Our earth is like a child who has grown up without parents, having no one to guide her... Some have attempted to help her but most have simply tried to use her. Humans, who have been given the task to lovingly steer the world, instead plunder her with no consideration, other than their immediate needs. And they give little thought for their own children who will inherit their lack of love. So they use her and abuse her with little consideration and then when she shudders of blows her breath. They are offended and raise their fist at God.

William P. Young

Forests ... are in fact the world's air-conditioning system-the very lungs of the planet-and help to store the largest body of freshwater on the planet ... essential to produce food for our planet's growing population. The rainforests of the world also provide the livelihoods of more than a billion of the poorest people on this Earth... In simple terms, the rainforests, which encircle the world, are our very life-support system-and we are on the verge of switching it off.

Prince Charles

In a world without any criticism at all, although there are many actors who would think they would be delighted to see that happen, would in fact be a far more problematic world than they could ever imagine.

Terry Teachout

As soon as the idea of the Big Bang was proposed in the 1920s, astronomers set about trying to work out when the bang happened. Initial estimates were, not surprisingly, wildly inaccurate, but by the 1980s it was known that the universe was 15 billion years old, give or take 5 billion years.

Simon Singh

Supposing we knew that up there is some alien civilization and it's sending radio signals our way we should not tell the public where that is. We could say that we've picked up a signal, but we should not tell them where for the simple reason that anybody could commandeer a radio telescope, set themselves up as some self appointed spokesperson of mankind and start beaming all sorts of crazy messages back to the aliens.

Paul Davies

The freedom I have as a U.S. citizen is unparalleled. Despite the fact people may not like American passports, having that passport affords me more freedoms than any other passport could.

Chris Cornell

Our planet has been around only for four and a half billion years. Let's imagine a planet that has life on it such as life is on Earth and it's seven billion years old. Let's say that planet evolved intelligence. Well, that intelligence would be way more advanced than what we call intelligence here on Earth. How long has intelligence been around on Earth as we've come to define it?

Neil deGrasse Tyson

Although humans have existed on this planet for perhaps 2 million years, the rapid climb to modern civilization within the last 200 years was possible due to the fact that the growth of scientific knowledge is exponential; that is, its rate of expansion is proportional to how much is already known. The more we know, the faster we can know more. For example, we have amassed more knowledge since World War II than all the knowledge amassed in our 2-million-year evolution on this planet. In fact, the amount of knowledge that our scientists gain doubles approximately every 10 to 20 years.

If we could magically transport ourselves back to the young Earth, when it was only a billion years old or two billion years old or three billion years old or four billion years old, we wouldn't be able to survive. We would have a hard time surviving if we were transported to the time when dinosaurs were around.
