...heard on the TV in the background while the main character is leaving the house.

Man, there is a xkcd for everything …

One of their neighbours has to be erratically throwing their family and stuff into the car, awkwardly saying hey to the main character as they jump in their car and speed off.

The summary bot didn’t even list the odd behavior. It has continued to decelerate a month after impact. Find that a bit unusual and counterintuitive to newton’s laws. But I’m not a physicist.

It's slowing down to look for the fucker that sucker punched him lol

It was an alien ship with camouflage and they ain't happy.

It appears to be slowing down. That means it's either generating thrust (outgassing etc), still being impacted by debris, or their measurements have been thrown off by something. All would be interesting, in their own way.

Somewhere a dev in the real world is scrambling to fix the bug in the simulation’s physics engine.

I guess they broke their engine! /s

To be fair, it's like playing billiards with a rope for a cue, in 3 dimensions, in zero gravity, with rocks for balls, and a coke can for the white, and the balls are moving.

I'm surprised they even hit it, give them a few years before you start expecting them to do trickshots.

They say, the dart was about the size of a fridge. It started in Nov 2021 and finished in Sep 2022. About a year later.

I say, there was still a pizza in the fridge.

Because, when you eat a year old pizza, it can slow you down a little, afterwards...

This is the best summary I could come up with:


However, a teacher and his class studying the rock have now discovered that since the collision, it has moved in a strange and unexpected way.

By crashing into the smaller asteroid, the Dart mission successfully altered Dimorphos' orbit by "tens of metres".

Dart, which stands for Double Asteroid Redirection Test, used a spacecraft around the size of a fridge.

By successfully crashing directly into Dimorphos, Nasa was testing if it could use similar methods to knock an asteroid off course, if one is in danger of hitting the Earth.

After discovering the unusual behaviour of Dimorphos, it's likely that Nasa will have to factor in the high school's findings, if they ever launch another asteroid redirection mission in the future.

The European Space Agency is launching a mission called Hera, which will arrive at Dimorphos in 2026 and could reveal more details as to what happened to the asteroid following the impact.
