All depends on the scale. If we’re early in the universe then there won’t be any others

This is why he opened with the caveat.... IF civilizations are common

[@printitpaintit.2436]

Depends what you're looking for, I can be invisible in a crowded room! 😆

Your talking about a civilisation so advanced technologically they would likely shield us from seeing them until we had worked through the sort of hurdles that might make us a threat. If you had a Dyson sphere it would be rather easy to use that sort of energy to project a portion of space and one billions of years might simply edit your perception. However the Fermi paradox has 2 simple solutions. Space is massive. The second is analysis of how atomic complexity has changed, the chemistry and physics of our corner of reality has only been capable of life for a relatively short timeframe.

I think that the need for intergalactic travel begins to grow smaller the better your technology becomes. Most civilisations probably end up downloading their consciousnesses into digital environments and that’s it. A whole species just downloaded onto a microchip that could be hurtling through space close to suns to generate enough power to run the technology. Or… even weirder… they learn how to transcend time and space all together before they become galactic explorers. When we see what we’ve been able to do with the elements available to us with technology… it doesn’t seem that far fetched that our need to actually search the corners of the galaxy would become limited. Augmented reality is in its early stages but it wouldn’t surprise me if even in 100 years we could download ourselves onto the web.

But we are a Ancient race. One day civilization will look to use as they creators

[@Nacee082]

We destroyed earth, on to our next challenge 💪🏾💪🏾

It might just be that there are other civilisations but they're just too far away

[@tomg224]

in 1mln years there won't be "to far away"

[@kwakuasare316]

Not necessarily there must be more civilisations. Maybe we could be the most intelligent life forms. If let's say there where no humans and we got wiped out millions of years ago or wherever we evolved life forms today wouldn't have a clue about stars, solar systems the sun etc. So maybe we are just the most intelligent. Someone has to be the most intelligent Maybe it was us. Monkeys, birds, the dinosaurs weren't close to evolving to humans intelligence, well I can't say dinosaurs as we just don't know

[@thehouseofdowney]

First of all, we do know the size of dinosaur skulls and therefor their brains and we are certain they had minimal intelligence, similar to other modern reptiles. However given the scale of the universe its just hard to believe we would be the most intelligent, what makes us special?

[@SimonGildos]

It's already happened.
