Virtual particles. Just because something can happen it does.

The fact that virtual particles actually exist. When they pop into existence as a pair, (pair for conservation of charge/spin/momentum whatever) if one of them is over the event horizon of a black hole they can never get back to each other to annihilate so that's the reason black holes emit radiation. The virtual particles 'borrowed' energy to create themselves, and this energy deficit needs to be made up because they can't annihilate and re-release it, so to preserve the conservation of energy the universe takes some energy from the blackhole which is why blackholes "evaporate" over time.

The fact that we know all this about blackholes despite never seeing one, and have deduced it using nothing but the power of our minds.

That doesn't make sense. The earth moves in an eliptical orbit, and the difference between being tilted slightly away from earth is way less than the difference cause by being at the apogee or perigee of orbit.

Elliptical orbits don't make sense as a reason either, because seasons are opposite in Australia.

The seasons are a product of eliptical orbit AND non-perpendicular rotation.

When the Earth is close to the sun, we get Summer and Winter. Summer for the side with the pole facing toward the sun, Winter for the pole facing away. Yes, that means Summer in the North hemisphere happens when Winter happens in the South hemisphere.
If our Earth's rotation was at 90 degrees to the plane of our orbit, we wouldn't have four seasons, we'd have two - near the Sun, and far from it, but we'd have each season twice a year. There might be differences between the first and the second ones, but it likely wouldn't be noticeable.


We get Autumn and Spring when neither pole is directed towards the Sun - because of the Earth's constant rotational speed, each part of the planet would get (at the furthest point from the Sun along the orbital pathway) twelve hours of sun, and twelve hours of dark.
The build up and down to this point is what gives us Autumn and Spring.

If you don't get it, go back and see if you can understand basic time keeping skills, how the Sun works, and, failing that, shoot yourself.

strictly speaking, this isn't true. yes, we would be much better off if we'd developed nuclear power and the corresponding infrastructure from the 60's instead of abandoning it, much like how France did. curiously, this seems to be the only thing they're good at aside from making wine and cheese, read into that what you will. the idea that there's a safety rick of nuclear power is a ridiculous media-fueled delusion. done properly, nuclear power is completely safe, but like anything if your'e stupid about it, it can be dangerous. just look at chernobyl vs fukushima.

however, that being said, today constructing enough nuclear plants to meet power demands would be incredibly cost-prohibitive and cannot plausibly meet projected world energy demands. according to the department of energy, even if a new plant was brought online each day for the next fifty years, the power demands would outstrip production by a large margin.

so, yes, stupid paranoia over the almost non-existent risk of meltdown did fuck us over, but also it couldn't save us now anyway. fingers crossed for a breakthrough that makes fusion or solar efficient, i guess

Meidums other than vacuum have a lower lightspeed limit.
The lightspeed limit in these mediums are however possible to violate.

Seasons are not caused by the Earth being closer to the Sun in the summer than in the winter. In fact, the Earth is farthest from the Sun when it is summer in the Northern Hemisphere. Seasons are caused by Earth's 23.4-degree axial tilt. As the Earth orbits the Sun, different parts of the world receive different amounts of direct sunlight. When an area of the Earth's surface is oriented perpendicular to the incoming sunlight, it receives more radiation than when it is oriented at an oblique angle. In July, the Northern Hemisphere is tilted towards the Sun resulting in longer days and more direct sunlight; in January, it is tilted away. The seasons are reversed in the Southern Hemisphere, which is tilted towards the Sun in January and away from the Sun in July.

Here's something more mindblowing:

Let f(x)= (-1)^x.
Differentiate it normally. f'(x)=[(-1)^x](log(-1))
Now differentiate it another way:

(-1)^x=(i sinPI+icosPI)^x=i sin(xPI)+cos(xPI)
Thus f'(x)=PI(i cos(xPI)-sin(xPI)

Equate them.
(-1)^x[log(-1)]=PI(i cos(xPI) - sin(xPI)
Put x=0,

You can measure maximum entropy in a volume by calculating how much entropy a black hole core that takes that volume can have.

To represent Graham's number, you'd need so much information and so much entropy, that if you were to fully comprehend it, the amount of accumulated entropy in the volume of your head would be larger than the maximum allowed entropy of a black hole taking that volume.

Your head would LITERALLY implode

I mean this in a nice, courteous manner-
Probably not. Actually understanding what P=NP requires enough knowledge of computability theory to understand what the problem is even *talking about,* any explanation you're given before you have a good grounding in what polynomial-time computability capacities are is going to bastardize the explanation the the point of meaninglessness. Tip: if they talk about how P is "easy" and NP is "difficult," they're not giving you an accurate description.

This just isnt true. What if the P algorithm takes something like (Gram's number) * n to complete? Then, the algorithms we have to factor numbers (all of which are NP) will execute faster than our P algorithm for practical numbers.

it's stupid to worry about whether our definitions of life happen to include fire or not

because face it: fire is not alive

it doesn't matter if it's alive or not, because that doesn't change what we know about fire. What matters is how we describe something, and since we can describe fire perfectly fine without worrying about whether it's "alive" then we don't need to worry about that.

it's pointless and unscientific

That's not because the men didn't choose to reproduce, it's because they killed each other and the survivors celebrated with a lot of raping various women. It's not so much the constraints of 'conservative' society, it's just a lower incidence of warfare and conflict in the modern world

Time Dilation

This one was crazy to me. It made sense, but it was too grand of an idea to accept easily.

Because the rate of time is dependent on velocity, the universe we live in contains the past and future. What appears to be present is decided by the difference in speed between the objects you're comparing.

Therefore, the objects far out in the universe, whose light we see is from the past, are at a certain time in their history relative to ours based on the difference in speed.

If the earth had been travelling at a different speed throughout it's history, it would have developed at a different rate in relation to the "rest" of the universe. Therefore, at this point in history on earth, if you looked out you would have a different view than you do currently, while the earth is travelling at its present speed.

Bullshit. It's because women are cheating whores and men are indiscriminate horndogs.

Which has vastly improved the gene pool.

What women want sexually is the best man around. Unless she's the best woman around, she won't get him in a monogamous relationship. But she also wants an ostensibly monogamous relationship, for security. So she bonds with one man openly and sleeps with others secretly. And thus, her children have higher genetic quality.

In polygynous societies, it's a little easier for a woman to get hooked up with a high-quality man. But women still cheat, especially since their husbands have other wives to keep track of.

For me, it's the idea of a virus.
A plasmid is a short strand of DNA that operates outside the chromosome. It replicates independently of mitosis and can code for proteins just like any other DNA. At some point, a plasmid happened to split off from a cell with a little chunk of membrane. By random chance and natural selection, that plasmid was able to fuse with cells it encountered and hijack the cell's machinery, replicating itself and sending off more little copies. Because it doesn't have a whole chromosome to deal with, just a short DNA program, it can mutate quickly and adapt to 'outsmart' any opposing biological processes. We call this a virus.

It isn't much of a living thing, it's just a self-replicating program that must hijack a cell to survive. Every medical symptom of a viral infection is some trick the virus learned (without thinking) to increase its survival. Coughing germs on to people, flooding your nasal cavity with mucus to make you sneeze, etc.
