“If I die trying but I’m inadequate to the task to make a course change in the evolution of this planet…okay I tried. The fact is I tried. How many people are not trying. If you knew that every breath you took could save hundreds of lives into the future had you walked down this…

“Look and think before opening the shutter. The heart and mind are the true lens of the camera.” -Yousuf Karsh Every time you shine light through a lens or reflect it off of a mirror, no matter how good it is, a portion of your light gets lost. Today’s largest, most powerful telescopes don’t even…

“Suddenly whole new programs open up, things you can do that you could never do before. It’d be great scientifically, it’d be great for the nation, for educators, for students, and it’d be just great for the public at large.” -Garth Illingworth Looking farther and farther into the distant Universe is the equivalent of looking…

“Einstein’s gravitational theory, which is said to be the greatest single achievement of theoretical physics, resulted in beautiful relations connecting gravitational phenomena with the geometry of space; this was an exciting idea.” -Richard Feynman For over a century after the publication of General Relativity, it was uncertain whether gravitational waves were real or not. It…

“The surface of the Earth is the shore of the cosmic ocean. On this shore we’ve learned most of what we know. Recently, we’ve waded a little way out, maybe ankle-deep, and the water seems inviting. Some part of our being knows this is where we came from. We long to return.” -Carl Sagan Here…

“Day after day, day after day, We stuck, nor breath nor motion; As idle as a painted ship Upon a painted ocean. Water, water, every where, And all the boards did shrink; Water, water, every where, Nor any drop to drink.” -Samuel Taylor Coleridge Here on Earth, water can easily exist in all three phases…

“The more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction.” -Rachel Carson The idea that the spatial fabric of the Universe itself is expanding, and that’s what’s behind the observed relationship between redshift and distance has long been controversial,…

“Hubble often takes images of distant gravitationally lensed galaxies to infer their substructure and to try to learn about early galaxies in general. For LUVOIR, we would have that same resolution for any galaxy! That’s truly revolutionary.” -John O’Meara If you were an observational astronomer, what would your dream telescope look like? It would have…

“The physicist is like someone who’s watching people playing chess and, after watching a few games, he may have worked out what the moves in the game are. But understanding the rules is just a trivial preliminary on the long route from being a novice to being a grand master. So even if we understand…

“There are so many people who are arguing or fighting over issues which don’t have much relevance. We must all realise it is not worth it. It’s like being in the whirlpools which are always present behind a little rock near a river. We seem to be living in these little whirlpools and forget that…
