Motivational Quotea by Adam Riess

We know there is   gravity because apples fall from trees. We can observe gravity in daily life.   If we could throw an apple to the edge of the universe, we would observe it   accelerating.

One of the most   exciting things about dark energy is that it seems to live at the very nexus   of two of our most successful theories of physics: quantum mechanics, which   explains the physics of the small, and Einstein's Theory of General   Relativity, which explains the physics of the large, including gravity.

It's everywhere,   really. It's between the galaxies. It is in this room. We believe that   everywhere that you have space, empty space, that you cannot avoid having   some of this dark energy.


Your chemistry   high school teacher lied to you when they told you that there was such a   thing as a vacuum, that you could take space and move every particle out of   it.

We look at distant   exploding stars called supernovae, and we've developed techniques to measure   how far away they are and how fast they're moving away from us.

Dark energy is   incredibly strange, but actually it makes sense to me that it went unnoticed,   because dark energy has no effect on daily life, or even inside our solar   system.

During my time at   Watchung Hills Regional High School, I was fortunate to have a number of   teachers who inspired me and filled me with enthusiasm for learning.
