Is There A Shadow Biosphere? Life On Earth That Isn't Related To Us

Hi everyone, a quick note. I've been asked by viewers to start using the Premiere functionality of YouTube to hang out with people while the new episode is being first broadcast on YouTube, but that means that I can't give you the episode in advance. 

So, I'm trying an experiment this week, and uploaded the full 4K version to our Vimeo account, which is hidden behind the Patreon system, so only you can see it.

The advantage to this is that you'll get the episode without ads. :-)

But, if you do want to hang out and watch the Premiere with me, you can do that too.

Here's the info:

Whenever I talk about the search for life in the Universe and its emphasis on water, I get comments that scientists aren’t being creative enough. Why does life rely on water? Couldn’t there be lifeforms which are completely different from life on Earth? Isn’t that the textbook definition of alien?  

Astrobiologists have only scratched the surface in their search for life in the Universe, and they’re going after the low-hanging fruit. Since life on Earth can be found wherever there’s water, why not check out the water on other worlds? If that doesn’t pan out, then they’ll expand the search.  

But it’s possible there are aliens living right here on Earth among us, in a shadow biosphere, we just haven’t detected them yet.
