earliest leak maybe per sphere year
Our television transmitters leak out from the Earth. And actually, there's a sphere surrounding the Earth from the earliest television signals, maybe 70 years ago, that's going out one light year per year. But it's really weak.
motivation inspiration long
We, all of us, are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.
ocean thinking years
The space that we're looking through is nine-dimensional. If you build a mathematical model, the amount of searching that we've done in 50 years is equivalent to scooping one 8-ounce glass out of the Earth's ocean, looking and seeing if you caught a fish. No, no fish in that glass? Well, I don't think you're going to conclude that there are no fish in the ocean. You just haven't searched very well yet. That's where we are.
technology our-world long
In the future, will our technologies help stabilise or planet and population, leading to a very long lifetime for us? Or will we destroy our world and its inhabitants, after only a brief appearance on the cosmic stage?
stars hydrogen giants
Earlier generations of stars in the galaxy could well have had planets. But really, there was only hydrogen and helium to work with, so they'd all be gas giants and not small, rocky planets.
stars blood hands
We are made out of stardust. The iron in the hemoglobin molecules in the blood in your right hand came from a star that blew up 8 billion years ago. The iron in your left hand came from another star. We are the laws of chemistry and physics as they have played out here on Earth and we are now learning that planets are as common as stars. Most stars, as it turns out now, will have planets.
