Where is everybody - the Fermi Paradox
Discussion
Old(ish) stuff in all honesty but interesting (truth be told pretty much noggin frying) non-the-less, along with some scary thoughts...

I love waitbutwhy stuff.
This one always brings me crashing back to reality on a Friday afternoon....

Universe distances are hard to wrap your head round. Mind boggling.
The observable universe is said to be 93 billion light years across. Travelling at the speed of light - the fastest physical speed known possible - is itself hard to fathom, but having to do it for 93,000,000,000 years? Wow.
But that's the observable universe; the bit that we can see and speculate on because it's light has managed to reach us. According to the theory of cosmic inflation, the entire size of the universe is estimated to be 10^23 that of the observable universe.
I'd love to know what's out at the edge of the universe. I don't imagine it's a brick wall. The universe is expanding into ........... what, nothingness? Infinity? The theory that it's infinite is slightly troubling in itself because infinity, by its definition, means there are no limits, no end.
Infinity means everything that can be........... is.
Everything that can possibly exist ......... exists.
Every set of circumstances that can occur .......... is occurring.
It means there is potentially another you sitting somewhere else in the universe right now reading this same thing. But maybe eating something different, or scratching their nose on the other side.

It's all part of the cosmic unconsciousness.The observable universe is said to be 93 billion light years across. Travelling at the speed of light - the fastest physical speed known possible - is itself hard to fathom, but having to do it for 93,000,000,000 years? Wow.

interesting stuff...maybe we are the type III civilisation and we're as advanced as it is possible to be and as we develop we are the ones at the boundary edge...https://waitbutwhy.com/2014/05/fermi-paradox.html
maybe in 3.4 billion years other civilisations will think the same thing....
we'll all be shadows and dust by then

It puts the average lifespan of a human into perspective! Not an entirely pleasant feeling to be honest.https://waitbutwhy.com/2014/05/fermi-paradox.html
Advanced for less than 100 years against billion year time frames. The chances of finding or being found is improbable. Imagine if advanced species visited earth when dinosaurs roamed, 300 million years. Hell even 80k years ago.
We need a million probes and a lot of time. It think it could take a million years.
