Not sure why you were down-voted. Isaac Arthur's perspective is that a species with the opportunity to expand would turn ever star into a Dyson swarm which, in turn, would darken the stars. If ET existed, the night sky would be dark.
- TheOtherHobbes 9y agoWhy would they? Using stars for energy is a human-scale idea. The majority of alien-scale ideas are likely unimaginable in our current state of development. Trying to imagine them is like trying to build a Haskell compiler out of rocks.
- chmike 9y agoIndeed. Our expectation that ET would have an interest in colonizing planets may be wrong. With a space vessel, they would have a perfectly adapted and mobile environment. They can avoid danger and explore to accelerate their technological and scientific evolution. We are still rooted on the ground like vegetals while they could move freely like animals.
- politician 9y agoArthur doesn't assume that they would build on planets, but rather build swarms of habitats orbiting the local star. A Dyson Swarm would gradually fill in around the star reducing its luminescence.
- flukus 9y agoThat assumes that all species are expansionist. Even our own species halts it's population growth once a certain standard of living is achieved.
- marcosdumay 9y agoYes, it assumes that. To put it fairly, every other species on Earth is expansionist, and ours has still expansionist subgroups that, if things keep going this way, will take over he rest of the population in a couple of centuries.
