As pointed out above, the slowing down of time has a lot more qualifiers on it. An observer very far away would see a falling body appear to slow down in time as it approached the event horizon. They would also see it red shift, quite rapidly, so it would still disappear from being visible, but not because it appears to fall through the event horizon.

For an observer falling into a black hole, as for any other observer, their own time would appear the same as always. Nothing special happens to the observer at the event horizon. If you were in a small ship with no windows, and the black hole was large enough that there wouldn't be a large difference in pull from the front and back of the ship, you would have no way of knowing the exact moment you cross the event horizon when falling through.

If you did have a window, you wouldn't see all time pass either. This seems to be more blatant wrong than just unqualified. Assuming GR works within the event horizon, the observer would hit the center in a finite (and actually quite short) time, the whole time still seeing stuff in front and behind them, with some time dilation. The only way to get infinite blue shifting of the rest of the universe, so that you could watch all time pass by, would be to stop yourself from falling right at the event horizon, requiring infinite force to stop your fall (and this all assume that quantum mechanics doesn't do something weird right at the event horizon).

We might actually get to see some of this more directly confirmed or proven wrong in the next couple years, as the Event Horizon Telescope, a network of radio telescopes, might be able to resolve the event horizon of the black hole at the center of the Milky Way.

I would rather the Mr. Fusion ran on water so that the empty beer cans be saved for the beer-can-refilling machine plugged into the Mr. Fusion.

These ideas mostly predate the modern science concept of testing by experiment and observation, and some even come from the time when philosophers thought reality could be derived from logic alone. Their persistence had a lot to do with momentum.

If the escalator is past a certain capacity, the the efficiency of the whole becomes the efficiency of the individual. In that situation the time saved walking is lost waiting to get on due to other people walking.

There are many cases where forcing people to wait can make every person get there faster, even for the individuals who have to wait longest. This is heavily studied for road traffic. You can have situations where a road with no cross streets will perform better with a stop light to pace people, such that even the first person stopped at the light, who has to wait the longest, will get through faster than if they didn't have the light.

The problem is these fixes tend to be for only certain high traffic scenarios, and a bad implementation will make other scenarios worse. Additionally, people complain heavily and will insist it is slower even when someone else measures it with a stop watch. At the end of the day, perception of speed matters more than actual speed for things like road and foot traffic.

That is only true because you chose the word "and" instead of "or."

It snows enough in SWFL that you would see snow in the sky at least once before making it to adulthood, unless you slept through it multiple times. That said, I didn't see accumulated snow until I was 20, and remember many kids finding stereotypical winter and Christmas decorations to be a bit abstract with all of the snow themes.

She names more than half a dozen different actions that fall under learning to give someone respect, and only one of them involves spending money.

If this is in Johannesburg, the police probably won't be coming and you've already been called by a private security company that you've previously contracted and who are familiar with your alarm setup. The guys coming to your place with dogs and guns will be the private security from a company you chose. If you want to see a real threat to your family's from security systems in South Africa, you should see some of the security gate and fence arrangements that make it take 5+ minutes to get out of the back of your house in the event of a fire. This all assumes you're lower-ish middle class or better and can afford all of that.

If you're going to hit so many of the most common fallacies and fallacious, trite sound bites, while claiming to be well studied and above tripe, others are going to assume you are using a trolling checklist.

I find your anti-America spin particularly amusing, as it likely runs counter to most people's experience when traveling. Having been to science conferences both in the US and elsewhere, there is a huge difference with vastly more emotional response against climate change research in the US (both from a subset of the scientists at the conference and the public I've meet outside the conferences). On the other hand, there have been enlightening discussions of issues and criticisms of the details of specific climate models, but involving people who don't get basic physics wrong. But those discussions run completely orthogonal to the criticisms seen on TV, newspapers, most websites, and comments similar to yours (and lacking the supercharged emotions and loaded absolute statements).

I also find it funny how often people champion a cause by talking about how much people on the other side just regurgitate what they've heard elsewhere. Except plenty of people everywhere, on both sides of almost all issues, will repeat things with varying lack of critical thought. The existence of such people is irrelevant to what side is actually correct for most such issues.

The location of the caption can depend on your play back device.

The accuracy can also depend on the device too, as some online streaming services, and definitely over the air transmissions, will have garbled CC. The small mistakes they show are nothing compared to the mess I've seen over the years, ranging from TimeCube-esque coloring schemes to what looks like captioning by the Swedish chef (not to be confused with actual captioning of the Swedish chef, which makes videos like this one worth a second watch).
