Explore big discoveries that have revolutionized our understanding of the universe.
How big is the universe? If it began with the Big Bang, will it also have an end? Is there life beyond our planet? Questions like these inspired the launch of Voyager I in 1977 and have driven innovative space research and exploration ever since. Trace ground-breaking discoveries that have transformed our picture of the universe, from an age when we knew of no planets beyond our solar system, to today, when we have evidence of thousands and estimate trillions more. And follow the teams trying to solve two of the biggest mysteries in cosmology today: What are dark matter and dark energy?

Anyone who missed this Speilberg film made 24 years ago MUST see this film which is much more relevant now than it was then. - JW
David, an artificial kid which is the first to have real feelings, especially a never-ending love for his "mother", Monica. Monica is the woman who adopted him as a substitute for her real son, who remains in cryo-stasis, stricken by an incurable disease. David is living happily with Monica and her husband, but when their real son returns home after a cure is discovered, his life changes dramatically.

Can't re-watch it again
I was 13-14 when I watched this movie. It's a long movie if I recall it correctly. I was so moved by it's theme, so I watched it all. I had strong feelings of sadness and sympathy towards little robot David that wanted to be a real child and to have a mom to love him. And that little bear ... I cried during some scenes. I don't ...
The Mass of Nows:
A Temporal Foundation for Inertia and Gravity

For a century, physics has lived with a quiet asymmetry. Special relativity shattered absolute simultaneity, forcing us to accept that "now" is observer-dependent—an infinite stack of "now-slices" foliating the four-dimensional block universe.
Yet when we turned to dynamics, to the origin of mass and force, we continued to treat space and time as a smooth, empty stage on which particles play. Inertia and gravity were described with exquisite mathematics, but their common cause remained mysterious. The equivalence principle told us they feel the same, but never why they are the same.
The Mass of Nows proposes a simple, radical answer: the stage is not empty. Between the infinite now-slices lies a dense plenum—the zero-point fields of every possible now, permeated by the four-dimensional extent of every particle's wave function.
Mass is not a property particles possess; it is the ...
