WHY NOT! Just because we/they haven't witnessed, seen or proved something exists does not preclude the possibility of it existing.

Approaching asteroid? Is this THE one?

You have electromagnetic radiation as fast, because it is (virtually) weightless.

Anything else e.g., mass particles are going to need large amounts of energy to accelerate them and, of course, a 'vacuum' is not really a vacuum, containing much to impede the acceleration of material particles.

I think it would take a lot more energy to move even the smallest useful asteroid than to install smelting equipment and ferry the ore back.
