To put things into perspective, the ability to traverse from galaxy to galaxy is impossible even with Star Trek warp technology. Traveling to the far reaches of own Milky Way galaxy (100,000 light years) is also impossible. So even with the ability to travel far beyond the speed of light, we’re still limited to distances of only about several hundred light years away, which is just a fraction of the Milky Way Galaxy.

Here is where I become even less optimistic. I think intelligent life is abundant in the universe, no doubt, but perhaps not within in our own galactic neighborhood. When I say galactic neighborhood, I’m talking about the distances that can be travelled with Star Trek warp technology, and that’s where we could find the existence of intelligent life to be quite limited.

As insanely huge as those numbers are, it's actually far greater than even that. Andromeda alone has approximately ~1 trillion stars based on the most recent Hubble imaging. It's absolutely mind blowing, and there are galaxies that just dwarf Andromeda. Andromeda is 220,000 light years across from end to end compared to the Milky Way at 130,000. The largest spiral galaxy is 832,000 light years across. One of the largest cluster galaxies is IC 1101 and it is 5.5 million to 6 million light years across with an estimated 100 TRILLION stars! What?!

The largest galaxy ever discovered is Alcyoneus, which is 22million light years across. It's a radio galaxy shooting massive lobes out of each side.

The latest research posits there could be as many as ~2 trillion galaxies in the observable universe alone. It's astonishing.

When I think about all of that out there and how great the distances are between bodies, how could there not be life somewhere else?
