Fraggin' Bastiches
so after going back through the last few chapters again, i'm not really convinced that stars were actually destroyed at all.
blast straight up says that the collision between saitama and garou will "blow earth to smithereens" (not the solarsystem or galaxy)-
blast couldnt contain that energy alone, so then his 3 underlings (who all seem to be weaker than blast himself) arrive to help contain and redirect it-
but as you see above; it looked like they just redirected the energy to an area very close to the earth, which was shown again on the next page-
so i think the black hole we saw here-
could just be a temporary after effect of the gateway that blast and his underlings opened. because the art in the prior pages definitely didnt allude to them redirecting the energy thousands of light years away from earth IMO.
there's also the fact that if blast couldnt even contain and redirect earth busting energy by himself, its hard to believe that with the help of his 3 weaker buddies, they would be able to contain and redirect an energy that allegedly destroyed hundreds (possibly thousands) of stars. the fact that saitama and garou's even more serious fight on IO was only moon level in scale just helps support that.
but thats just my speculation. we dont know all the facts yet.
