They also appeared to have a significant proportion of their deposits effectively controlled by one person where that individual telling all his portfolio companies to withdraw there deposits was enough to eat up the banks liquidity.

The exception is probably when cast iron is used for searing. If all goes well, that should significantly exceed the temperature kitchen silicone mats can handle.

Edit: adding to the comment of someone mentioning size because that is what makes it an interesting target for a basic camera.

This isn't quite the same as seeing it with your own eyes. A digital camera that can do a 10s or so exposure with a delay on a cheap tripod can get you a picture in less than ideal conditions for naked eye viewing. The delay is because I am going cheap, so don't have a remote, which gives time for vibration from pressing the button to die out.

And being so big (and fuzzy), no need for zoom which makes it fairly easy to aim in the general right direction, and end up in frame.

Also, for exo-planets, in particular, we have a decent idea of what to look for for earth-like life. Claiming some other observation is a sign of non-earth-like life is a much more difficult conclusion to make.

To expand a bit, aside from the early universe point in terms of how we get anything smaller than a gas giant for dark matter. One thing that is possible even for hard to detect ordinary matter is that even non-detection sets limits for the size and quantity of those objects. So, surveys watching for occultations and gravitational lensing events on stars in Andromeda or distant galaxies or quasar by these objects if they made up the Milky Way's dark matter halo set limits on the size and quantity of planet sized objects and even planet mass primordial black holes. I believe the current boundaries for size and quantity of objects that have not been eliminated as significant dark matter contribitors is pretty small right now.

More massive black holes have larger event horizons.

You are thinking like space elevator where something pulls just a little harder than gravity can make its way up. Basically, if you apply a force of 1.0001g constantly from the earth's surface you move up from the earth's surface. There is no x.000001g that allows any object to move up inside a black hole event horizon.

They don't. Hawking radiation doesn't come from inside the event horizon. I am trying to paraphrase Matt O'Dowd here, but the short short version as I understand, an event horizon causes certain frequencies in quantum fields to no longer cancel. The effect is that, for an observer far away from the black hole, the black hole emits radiation. The energy comes from the mass of the black hole, I don't think anyone really knows how that happens since we don't really know what a black holexs mass is made of (if anything),

So, once the object dips below the event horizon there is no forcethat can make any part of the object below the event horizon move "up". I think that might be your confusion, thinking that a cable can somehow apply a force and thus an acceleration that a rocket or other form of propulsion cannot. Yes, in a sufficiently large black hole, the difference in force between the top and bottom of the object might be not be enough to rip it apart, but there is still no force that will allow the object to climb towards the event horizon.
