This thing is pretty cool, I got to see hubble launch when I was 14 and now my 14yo gets to witness Webb. I hope he has the same reactions to Webb as I did with Hubble images

I think it’s very different, because a giant meteor/comet/black hole hit on planet Earth might not be something where we can just “learn to mitigate the damage” - such things could be near-extinction events, which we know have happened in the past. Furthermore, we KNOW the the sun will eventually expand and engulf Earth. While that is obviously VERY far in the future, it is known event that is likely going to make the planet uninhabitable.

The JWST will increase the size of the visible universe by several billion light years, by this time next year the universe will probably be much bigger than we thought.
The hubble deep field got us to around 12-13b years visible age of the universe. However at a certain point the light from those distant galaxies is to far shifted to the red for hubble to detect because Hubble didn't have much IR capability. The current consensus is that there is only an extra billion or so years of visible universe beyond the current hubble deep field - at that point the earliest galaxies are hidden by dense primordial clouds of hydrogen and helum created during the big bang. The JWST will see a lot deeper into the IR spectrum so there is a good chance it will reveal scores more galaxies beyond the limits of hubble's deep field, and even reveal galaxies hidden in the primordial soup of the early universe. My personal guess, we won't see the primordial gas created from the big bang condensing into the earliest galaxies. We're going to see red-shifted galaxies going back back and back. All the way to the limits of the JWST making the universe 20, even 30b years old, and it will vastly change the current model of the evolution of the universe. |

Works for me. Tower Assembly has been successfully deployed:
The Deployable Tower Assembly (DTA) is deployed. The tower extends 1.22 meters. This movement/distance provides needed separation between the spacecraft and telescope to allow for better thermal isolation and to allow room for the sunshield membranes to unfold. Prior to this, several release devices will have been activated, and various heaters, software, and electronics have been configured to support deployments. This deployment motion is driven by a motor. View Quote |

View Quote Starlifting is a good strategy for a Kardashev II civilization. The star will outweigh everything else in the system, as will its share of elements not contributing to fusion. The one thing I wonder though is that G-class stars like our Sun aren't fully convective. Unlike M-class red dwarf stars. That means if we "clean" the Sun of heavier elements, it may not actually benefit the core where the fusion is happening. Our future descendants might need a big stir-stick or something. |
