just learned about the "great filter", very interesting. I think it does mean that our observation tech is not good previously - it also sounds like if we did start observing life, the fact that we have yet to be visited / colonized by that life form means only re-affirms the unlikelihood of interplanetary travel..

according to [wikipedia](https://en.wikipedia.org/wiki/Great_Filter):

> So by this argument, finding multicellular life on Mars (provided it evolved independently) would be bad news, since it would imply steps 2–6 are easy, and hence only 1, 7, 8 or 9 (or some unknown step) could be the big problem.[4]

Imagine that, knowing there's intelligent life out there, but knowing we will never meaningfully interact with them because it's impossible to travel any useful distance or communicate in any real way. Even if we could travel vast distances, It seems likely if we discover any life out there it may be long dead by the time we get there.

that's really sad :(. 300 light years ... gonna take a while. maybe the filter is space travel - no civilization is able to amass enough energy to go those distances

We have an enormous, almost inexhaustible source of energy just 1 AU away.
