Debra Fischer Quotes

Ultimately, what we're looking for in the long run is to find other Earth-like planets.

For many centuries, humans have speculated that there might be planetary systems around other stars and that there could be extraterrestrial life there and even intelligent being. However, those were simply speculations, and now we have evidence for the first part of these ideas.

With 'Extinction Machine,' I wanted to start some conversations about whether we're alone in the universe and what that might mean.

We're going to understand that there is life on other bodies in the solar system.

The bottom line is, like, one in five stars has at least one planet where life might spring up. That's a fantastically large percentage. That means in our galaxy, there's on the order of tens of billions of Earth-like worlds.

It's presumptuous for us to think we are the only beings in the cosmos.

To me, it's the kind of interesting question the human race should be investing in. Is there intelligent life out there? Are there other beings out there?

Life outside of Earth is probably going to be really hard to find.

We go to learn about our solar system, to search for life, and to understand what happened to Mars so we avoid it ourselves.

Among the plausible niches for extraterrestrial life in our solar system, the clouds of Venus are among the most accessible and the least well explained.

There are other planets besides the Earth and Mars. I'd like to remind you that studying Venus is vital to understanding life elsewhere.

Theoretically, there are planets with an environment that can support life. As yet there is no evidence that there indeed is life on other planets. It's only a matter of time before we get to know.

A deep ocean under the icy crust of Ganymede opens up further exciting possibilities for life beyond Earth.

I do a lot of work with NASA and am involved in research projects studying planetary evolution, Earth-like planets, and potential conditions for life elsewhere.

The existence of life beyond Earth is an ancient human concern. Over the years, however, attempts to understand humanity's place in the cosmos through science often got hijacked by wishful thinking or fabricated tales.

I believe that there may be intelligent life on other planets.

We're all interested in life outside of Earth. We all have a fascination with what's out there because we don't really know.

It might be arrogant to think that we're the only living creations in all of the solar systems that there are. Space is so vast.

Exploring and colonizing Mars can bring us new scientific understanding of climate change, of how planet-wide processes can make a warm and wet world into a barren landscape. By exploring and understanding Mars, we may gain key insights into the past and future of our own world.

Maybe the search for life shouldn't restrict attention to planets like Earth. Science fiction writers have other ideas: balloon-like creatures floating in the dense atmospheres of planets such as Jupiter, swarms of intelligent insects, nano-scale robots and more.

We can never prove that we're alone in the universe. But the Allen Telescope Array could prove that we're not.

I actually think the chances that we'll find E.T. are pretty good.

It's just too egotistical to think that we are the only lifeform in the universe.

Wonder if there is life on another planet? Let's suppose there is. Suppose further, that only one star in a trillion has a planet that could support life. If that were the case, then there would be at least 100 million planets that harbored life.

Mars is the only place in the solar system where it's possible for life to become multi-planetarian.
