The enormous distances between things in space as well as the speed limit of c make me think it's pretty likely we will never make contact with any other advanced civilization elsewhere even though there is no way there aren't billions of them out there. Space is so empty the average temperature of it is only like 3 Kelvin. E.g. 3 degrees celsius above absolute zero.

Yep, just completely mind blowing how small we all really are.

But what data do they really get from those 1 second BLLOOOPPPPPPs? Unlike the spectral breakdown from JWST

They know now that if the can get the sensitivity up some more, they will be able to detect "less dramatic" events. They saw nothing until they upgraded the system and lucked out and had a confirmed detectable event since both facilities saw the Bloop like 2 days after the upgrade.
 
Lol.

Straight out of the first Star Trek movie.

Did it show up in the movie? I know it was in the OG series because when I was a kid they had some special where they broadcast the top 10 OG trek episodes and it was one of them so I ended up watching it like 20 times.

Maybe we will learn to fold space someday.

Was wondering about this possibility since the mirrors are not protected by a tube wall. Hope this does not occur regularly.

As mentioned earlier in the topic, it’s an edge segment. So impact to image quality is negligible. And to get an enclosed telescope, it would be HUGE!!!! Far too difficult to launch into space.

But there are discussions to avoid turning JWST towards certain parts of the sky to minimize it pointed in the line of fire to cosmic dust.

Micrometeroite and Orbital Debris (MMOD) are getting to be significant problems. Most of the risk comes from passage through low Earth orbit, but even out at L2 where JWST is there's always a risk of an impact with something to small to see.

There are technically solutions in General Relativity that allow for wormholes and Star Trek style Warp Drives. The problem is they require types of and amounts of energy that may not ever be feasible in the real universe.
