While theoretically possible, we don't see enough observable evidence to support this.
Additionally, think of this. At what specific point of size/mass would a black hole actually "explode" into another Big Bang? As far as we know, each black hole that currently exists at any size or mass is already infinitely dense. Even if you combined all the matter in the Milky Way Galaxy into one black hole, it would still be an infinitely dense black hole, it can't get any more dense than it already is. It *would* become more massive and have a larger event horizon.
But there's nothing fundamentally different about a solar-mass size black hole and a galactic core black hole, aside from just being much much more massive. Again, as far as I'm aware.

>with gold foil more ubiquitous than lead foil
Just to clarify, that doesn't necessarily mean that gold is found more commonly than lead, it's that gold foil was relatively easy to make compared to lead foil? Is that still true today?
I recall selling and using adhesive lead foil for adjusting the weight and balance of tennis racquets, for example. Most modern commercial uses of gold foil I've noticed seem to be related to artistic projects or embellishing food at fancy restaurants.

Mmm I dunno about that. There are plenty of moon craters you can see in these photos that would not form on earth because those small meteoroids would burn up in Earth's atmosphere. And the moon's surface is relatively light and dusty.

Anytime I get mad and slap a keyboard, I solve that problem and boom, I instantly have a different problem. Molotov cocktails work the same way.

Because it's very light dust that is electrostatically attached to the panels. Tapping wouldn't do much. And as other folks have mentioned, adding more complexity to the rover means a greater chance of failure and adding more weight, which means more cost, and that you have to choose what other scientific instruments you can't include because you have a maximum weight/cost limit.

Reverse the polarity in the deflector array by negative 5! I cannae captain, it won't respond!

It's not too difficult to make a mini Thanksgiving-style Sunday dinner!
Just get a small chicken and de-bone or spatchcock it. Dry brine overnight.
Roast with whatever veggies/stuffing/casserole you like, do potatoes/gravy/other veggies on the stove, along with whatever fresh stuff like kimchi/slaw/eggs you can make ahead of time.
Just make whatever quantity you want, whether it's for 1 person and you've got 3 days of leftovers (most of this freezes & microwaves pretty well too) or enough to serve a family of 5 with one day of leftovers!
