What If All Stars Exploded at the Same Time?

For every galaxy that's visible from Earth, there are nine smaller ones that we can't see, even with all the technology we've developed. That's 90% of all space stuff in the observable universe that we're missing out on. We can't even see all the stars in the Milky Way. Our home galaxy is just too cluttered with gas, dust, smaller stars and, well, one supermassive black hole. All that makes it impossible to tell how many stars there really are out there. But whatever that number is, it sure has a lot of zeros in it.
