# Quote — Max Tegmark, Our Mathematical Universe

> This implication of the Mathematical Universe Hypothesis is pretty radical, so please pause (…) take it in and think about it. What you’re aware of right at this moment feels not like a photo but like a movie clip. This movie isn’t reality—it exists only in your head, as part of your brain’s reality model. It contains lots of information about the actual external physical reality—as long as you aren’t dreaming or hallucinating—but still constitutes only a very heavily edited version of reality, akin to the evening news on TV, mainly featuring certain highlights of patterns nearby in space and time that your brain thinks are useful for you to be aware of.

> In 1814... Joseph von Fraunhofer invented... a spectrograph, which let him separate white light into into a rainbow of colors... He discovered mysterious dark lines in the rainbow... and... the detailed positions of these lines... depended on what the light source was made of, constituting a kind of spectral fingerprint. During the following decades such spectra were measured and catalogued for many... substances. ...Sensationally, the spectrum of sunlight revealed that the Sun... contained elements... such as . Moreover... it revealed that stars are made of roughly the same mixture of gases as the Sun! This clinched it in favor of Bruno: stars are distant suns...

> But I’ve suddenly changed my mind and turned more optimistic about our cosmic significance. Why? Because I’ve come to believe that advanced evolved life is very rare, yet has huge future potential, making our place in space and time remarkably significant.
