I believe one of the ideas that came out of the “Star Wars” Strategic Defense Iniative of the Reagan years was the idea that we could use powerful lasers to pulverize the asteroid into harmless debris.
Do we even have lasers that powerful? How much power would it even take to use light at a distance to destroy something as huge as an asteroid? I don't really know enough about lasers to know, but it seems like...probably a lot? 🤔
