Is Mining Asteroids That Impacted The Moon Easier Than Mining Asteroids Themselves?

https://www.universetoday.com/articles/is-mining-asteroids-that-impacted-the-moon-moon-easier-than-mining-asteroids-themselves

Asteroid mining is considered challenging due to engineering complexities such as landing on low-gravity targets and retrieving materials safely. A new study suggests mining fragments from asteroids already embedded in lunar craters instead. Simulations indicate asteroid remnants (especially inside craters larger than 1 km) may contain valuable materials such as platinum-group metals or water embedded in the lunar surface, making the Moon potentially richer and more accessible than near-Earth asteroids.

What If We Never Find Dark Matter?

https://www.scientificamerican.com/article/dark-matter-hunters-may-never-find-the-universes-missing-mass/

Despite decades of searches, physicists have yet to detect dark matter. Possibilities include WIMPs, hypothetical heavy particles interacting via the weak force, and QCD axions, ultra-light particles predicted by quantum chromodynamics. Other candidates include primordial black holes that formed in the early universe, exotic particles from an undiscovered "dark sector", and revisions to our understanding of gravity.
