When does the mega sunspot or whatever hafta fire a large mass ejection at us, and how strong would it have to be, to cook most of humanity?

The sun fires multiple ejections a day big enough to cook us. They just all miss. It would be like you stepping outside and shooting a bullet in a random direction a few times a day, with Earth being a golf ball miles away. The golf ball would be destroyed by a bullet. But your odds of hitting it are very low. Of course, over time the odds become an inevitability.

Why do people just make up things like this? Did you hear it somewhere and never research it?

Now I want to know on what date and time the lowest percent of the world's population will be in sunlight.

6 months and 12 hours later (or earlier) would be my rough guess.

Earlier quoted context omitted.

London has long benefitted from its position allowing its working day overlapping everywhere from the US West coast to Japan, even if barely at those extremes. Most of the world's population lies between UTC-5 and UTC+5 I believe.

Is that "most of the world's population" in the same sense as "Mohammed is the most common name?"

Well, is it?

...and if it is predictably half a year away?

It's not clear to me why the same isn't true for the 7th of June - ie, 17 days the other side of the solstice (for fuzzy values of solstice, depending where you're standing, etc).

Seems related to the fact that you can draw a surprisingly-small circle over part of Asia and have more people inside the circle, than out. Human geography is very uneven.

Lots of things on Earth are unevenly distributed. Mineral deposits, water, fertile land, mild climates…

... the future.

Australia: Our brother to the hot south with more sex appeal and far less marriage material.

I was just quoted a stat that said boomer retirees have sex way more frequently than any of their younger cohorts. So weird and depressing if true.

Maybe single people are less likely to retire

Not to be "that guy", but claiming that 4:15am in California (11:15 UTC) is daylight is really stretching it, at least going by this morning. Also sunrise here is ~5:50 AM. Even for a 7am meeting I typically need lights on in my office until partway through. The room has both eastern and southern exposure in the south-east corner (my desk is literally by the windows).

Australia has less than 1% of the world population? Edit: yep, around 0.3%

A few years ago I wanted to make my movie-watching more representative of relative populations of countries, so I made this list. Most strikingly, about 4 movies in each 100 I watch should be from USA.

Percentage of world population: China 18.5 - India 17.7 - USA 4.25 - Indonesia 3.5 - Pakistan 2.8 - Brazil 2.7 - Nigeria 2.6 - Bangladesh 2.1 - Russia 1.9 - Mexico 1.65 - Japan 1.6 - Ethiopia 1.5 - Philippines 1.4 - Egypt 1.3 - Vietnam 1.25 - DR Congo 1 - Turkey 1 - Iran 1 - Germany 1 - Thailand 0.9 - UK 0.9 - France 0.8 - Italy 0.8 - Tanzania 0.8 - South Africa 0.8 - Myanmar 0.7 - Kenya, South Korea, Colombia 0.6 - Spain, Uganda, Argentina, Algeria, Sudan, Ukraine 0.6 - Iraq, Afghanistan, Poland, Canada, Morocco, Saudi Arabia 0.5

It would be fascinating to ask people around the world - "What percentage of the world's population lives in your country?"

Wow, what a fun statistic! Even if it's pushing the common definition of "sunlight" quite a bit. Also makes me wonder what fraction of the world population is awake at a given time, and what that fraction looks like plotted against 24 hours of the day.

In Internet Census 2012, there's an animated gif of planet earth's day/night cycle as measured by which IP addresses respond to ping:
