Janna Levin Quotes

Maybe truth is just like that. You can see it, but only out of the corner of your eye.
Adele never demands of him any actual conversation. She seems to understand that she is there to keep time and drown out the alarm of more individuated noises. The clink of a pin drop that can fray his nerves, the grinding of gravel beneath the weight of a man on the street, the spike of a dulled conversation as a couple pass beneath his window over Langegasse, the mounting pitch of the conspiratorial exchange as they approach.

In the far future, which promises to be vastly longer than our past (like a googolplex of years to our future versus 13.8 billion years to our past), all of the stars in the universe will have run out of fuel. Those that can will collapse to black holes; eventually everything will fall into stellar-mass black holes, and those black holes will fall into supermassive black holes, and then all of the black holes in the universe will eventually vaporize into Hawking radiation. This will take a very long time. ("Eternity is a very long time, especially towards the end.") All of the Hawking radiation will dissipate in an ever-expanding cosmos, unable to fill the swelling void, and the light in the universe will go out. Eventually, ever particle will find itself alone, no bright sky above, no luminous solar systems below. For now, we're here and the skies are bright, if somewhat quite. The gamble is that the skies aren't silent.

Black holes can bang against space-time as mallets on a drum and have a very characteristic song.

His weakness in this game, and in life, is that he's never prepared for how others will act. They are predetermined but too complex to solve or predict, and there are rules that he is just no good at applying.

I'd like to convince you that the universe has a soundtrack and that soundtrack is played on space itself, because space can wobble like a drum.

We have to wonder, if there is a multiverse, in some other patch of that multiverse are there creatures?

I don't believe that math and nature respond to democracy. Just because very clever people have rejected the role of the infinite, their collective opinions, however weighty, won't persuade mother nature to alter her ways. Nature is never wrong.

To see some truths you must stand outside and look in.

An idea sparked in the 1960s, a thought experiment, an amusing haiku, is now a thing of metal and glass.

Sam Harris fearlessly describes a moral and intellectual emergency precipitated by religious fantasies
misguided beliefs that create suffering, that rationalize violence, that have endangered our nation and our future. His argument for the morality, the honesty, and the humility of atheism is galvanizing. It is a relief that someone has spoken so frankly, with such passion yet such rationality. Now when the subject arises, as it inevitably does, I can simply say: Read Sam Harris' Letter to a Christian Nation.

Topology and number theory are my faves.

Sure one could argue the naturalist's case that the mind experiences an external reality in which it participates. But how can this account really satisfy us, Olga? One could equally well argue that all experiences is highly subjective, that the only thing we really have is the image, the smell, the taste, and all of our assertions about the universe are constructions of the human mind.

We are all caught in the stream of a complicated legacy - a proof of the limits of human reason, a proof of our boundlessness. A declaration that were were down here on this crowded, lonely planet, a declaration that we mattered, we living clumps of ash, that each of us was once somebody, that we strove for what we could never have, that we could admit as much. That was us - funny and lousy and great all at once.

Now, our Sun will not collapse to a black hole. It's actually not massive enough.

Joe's scientific life is defined by these significant near misses… He was Shackleton many times, almost the first: almost the first to see the big bang, almost the first to patent the laser, almost the first to detect gravitational waves. Famous for nearly getting there.

This world extends beyond this room, Adele. There are the streets of Vienna and beyond that Europe and beyond that a globe in space in orbit around a star in a universe. But how do I know that for sure? I cannot see the globe spinning on its axis right now as I speak to you. How can I be sure? I can be sure because it's logical; the mathematics is sound and respected by the orbits of the planets. I can verify it's true, not by looking at it, but by thinking about it.

Forever is a very long time, especially the bit towards the end.

We have never observed infinity in nature. Whenever you have infinities in a theory, that's where the theory fails as a description of nature. And if space was born in the Big Bang, yet is infinite now, we are forced to believe that it's instantaneously, infinitely big. It seems absurd.
