Max Tegmark Quotes

(…) time is not an illusion, but the flow of time is. So is change. In spacetime, the future exists and the past doesn’t disappear.

I believe that consciousness is the way information feels when being processed.

Aristarchos of Samos... was able to use to figure out... the distance between the Earth and the Sun. His conclusion... the Sun was about twenty times farther... than the Moon and therefore twenty times bigger than the Moon. In other words, the Sun was... over five times bigger than the Earth in diameter. This insight prompted Aristarchos to propose the heliocentric hypothesis long before Nicolaus Copernicus... It turned out to be quite difficult to tell precisely when the Moon was 50% illuminated, and the correct Sun-Moon angle... isn't 87 degrees but about 89.85 degrees... This makes... the Sun... almost twenty times further away... and about 109 times larger than the Earth... [T]his wasn't corrected until almost two thousand years later, so when Copernicus came along... the overall scale of his Solar System model was about twenty times too small...

Yet the complexity of all this pales in comparison to the patterns of information processing in your brain. Your roughly 100 billion neurons are constantly generating electrical signals (“firing”), which involves shuffling around billions of trillions of atoms, notably sodium, potassium, and calcium ions. The trajectories of these atoms form an extremely elaborate braid through spacetime, whose complex intertwining corresponds to storing and processing information in a way that somehow gives rise to our familiar sensation of self-awareness. There’s broad consensus in the scientific community that we still don’t understand how this works, so it’s fair to say that we humans don’t yet fully understand what we are. However, in broad brush, we might say this: You’re a pattern in spacetime. A mathematical pattern. Specifically, you’re a braid in spacetime—indeed, one of the most elaborate braids known.

Some ancients speculated that the stars were small holes in a black sphere through which distant light shone through. ...Giordano Bruno suggested that they were... like our Sun, just much farther away, perhaps with their own planets and civilizations... the Catholic Church had him burned at the stake in 1600.

So with each advance in understanding come new questions. So we need to be very humble. We shouldn't have hubris and think that we can understand everything. But history tells us that there is good reason to believe that we will continue making fantastic progress in the years ahead.

Why do we perceive the world as stable and ourselves as local and unique? Here’s my guess: because it’s useful.

Some key physical entities such as empty space, elementary particles and the wavefunction appear to be purely mathematical int he sense that their only intrinsic properties are mathematical properties.

It depends... on what you measure outrageousness in... If what you mean is that something is more extravagant if it... involves somehow having more particles, or reality being bigger... then sure. But... maybe the kind of simplicity that we should value with Occam's razor is rather that the math is simple. The equations are simple.

The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom. Isaac Asimov

Your synapses store all your knowledge and skills as roughly 100 terabytes’ worth of information, while your DNA stores merely about a gigabyte, barely enough to store a single movie download.

[I]t's... a big mistake as a species if we don't create institutions and governments which support science. There have been a number of... economic studies that have shown... that investing in basic science is the highest return on investment, basically ever... Inventing the ... just basic... physics research... has benefited us so much, in so many ways... Inventing calculus... didn't cost that much, but it's... so, so valuable... This comes back to the whole media question again. There are much more people who have heard about the Kardashians than... can name three living scientists... let alone twenty. ...[W]e've created a culture where scientists... not only are they not particularly known... or viewed as role models or heroes, but they are even very actively attacked by... folks with power with whom what scientists are saying is inconvenient... One of the best things we can do for science funding is to create a less screwed-up media landscape where we actually appreciate how much we benefit from scientific research. That governments will actually support it again. ...We spend two billion dollars a day or more, in this county alone, on military... If you can get a puny, puny fraction of that into scientific research, we wouldn't even be having to have this conversation about how we get funding.

… when people ask about the meaning of life as if it were the job of our cosmos to give meaning to our existence, they’re getting it backward: It’s not our Universe giving meaning to conscious beings, but conscious beings giving meaning to our Universe.

measurements, so please let me take a few minutes to summarize 13.8 billion years of cosmic history.
