Things that blow my mind

Life:

...within a generation, biology will face its ultimate identity crisis. Researchers in the field of nanobiotechnology are racing to achieve the complete molecular integration of living and nonliving materials. We will hack into the CPU of life in order to insert new hardware and software. The purpose is to extend the capabilities of biology far beyond the limits imposed by evolution, to integrate the incredible biochemistry of life with the equally spectacular chemistry of nonliving systems like semiconductors and fiber optics. The idea is to hard-wire biology directly into any and every part of the nonliving world where it would be to our benefit. Optoelectronic splices for the vision impaired, micromechanical valves to restore heart function.

But the moment we close that nano-switch and allow electron current to flow between living and nonliving matter, we open the nano-door to new forms of living chemistry — shattering the "carbon barrier."

The universe:

The burst, named GRB 050904, originated 12.8 billion light-years away, which means it occurred 12.8 billion years ago and the light took that long to reach us. It erupted very nearly at the beginning of time.

You know, everything!
