****. My estimate = 2.22x10^13 species that match our intelligence.

I wonder if any of those can travel faster than light?

You're forgetting one thing: time.

There are entire galaxies out there that have been around a lot longer than our tiny milky-way galaxy.

Add that to the fact that there are 200-400 stars in our galaxy alone, most of them containing their own gravitational pull and solar system like our own. Times that by the number of observable galaxies (hundreds of billions) and you start seeing that the probability is extremely high. In fact, the probability of us being the ONLY intelligent life becomes laughable.

e=mc2 is based on the physics of our planet and Earth's gravitational pull. Beings living on another planet, with a different gravitational pull live by different physics. At least in theory.
