A new paper suggests an alternative strategy: why not capture a nearby asteroid and put it into an Earth-bound orbit to use as a shield?
Such an asteroid could then be moved as needed to absorb the impact of any collision that would otherwise hit the Earth.
A deceptively simple solution. I wish I'd thought of it.
