Reply to comment by Litalian in what will actually happen when we finally collide with Andromeda? by Wardog_Razgriz30

Pretty much this. I think there are gifs and videos of this being simulated too.

What I would like to add is that the merger and gravitational interaction of the matter within both galaxies will also result in a new burst of active star formation as the gases and nebulas within both galaxies are acted upon by various forces during the merger.

As for our Sun, it would be in its late stages, either nearing it or having already become a red giant and swallowing up the inner planets. So unless we have become a space faring species and spread out to other stars, we'd more likely be extinct.

Reply to Latest video of the Ingenuity Mars Helicopter kicking up dust and taking off for Flight #47. Ingenuity is well beyond its warranty at this point. The video was captured by the Mastcam-Z imager aboard NASA’s Perseverance rover on March 9, 2023. by ICumCoffee

So how does this helicopter differ than a similar helicopter that would be used in Earth? With Mars’ thinner atmosphere I would imagine that some alterations would need to be made to sustain lift.
