Distances between stars in a galaxy are so great that it will be near impossible for most stars or planets to collide. Though a few are likely to. We would almost surely still have our Sol And solar system as it has always been, just probably much farther from the center of our new galaxy than we were in our old. And this would apply to almost the entire galaxy. It would not be nearly as destructive as you probably imagine.

Edit to say that the most destructive part of the collision would likely be the force of gravity launching some entire stars, planets, and solar systems out of orbit entirely. Off into the darkness of space to freeze and float forever. This is also an unlikely scenario for 99% of both galaxies, but it’s still going to happen to some of them.

You are making up crap in your head. Look, 3 execs confirmed at multiple different times in multiple different interviews the cost. People have also gone through to verify numbers as best as possible. The Execs have no reason to lie. And reuse is not some gimmick. It's actually making a meaningful difference. Not just price, but cadence.

And yes, we do know the funding reasons. They specifically made a big deal about both Starlink and Starship. Plus we can see with our own eyes the huge production being done. Factories ain't cheap, nor is the huge amount of construction for Starship and the massive number of satellites for Starlink.

And of course common sense clearly shows that reuse is making a huge financial difference. If it wasn't, they wouldn't have reduced the cost of reusable launches, they wouldn't push customers towards reused rockets, and they wouldn't fly Starlink missions entirely on reused boosters. You are effectively accusing SpaceX of being a pyramid scheme when it clearly isn't.

Most people can’t grasp the enormity of an accomplishment like this. It’s just too big. In fact there are some who resent what this suggests about their plodding lives on earth. But the vast majority are in awe and wonder and it helps to elevate us all

Both impressive and the results of Atlas since operation shows it's doing a great job. A space-based telescope system would be able to do so much more, especially since it wouldn't have the limitations of only scanning the night sky that a ground one does. A key point - any impactor that is in a orbit similar to Earth's is that the last years of its path will be from the Sun side of the planet. The sooner we see anything and can calculate mass and vectors the sooner we can do any action that we might be able to do. Another key point - to be able to do anything like deflection we have to get to the object first long before its arrival, so knowing years in advance is crucial.

That's pretty cool, but not it.

I'm about 80% sure it was something that NASA (or perhaps another government agency) put together. They made a huge deal about it being in HD at the time (the first polar solar eclipse captured in HD from an airplane). I want to say they flew two planes and got it from two different angles, and chased the eclipse to experience totality for a bit longer.

It's kind of weird that I can't find it now. It's one of the things that got me really interested in astronomy when I was in high school.
