Here are some random fun facts
- A cloud weighs around a million tonnes. ...
- Giraffes are 30 times more likely to get hit by lightning than people. ...
- Identical twins don't have the same fingerprints. ...
- Earth's rotation is changing speed. ...
- Your brain is constantly eating itself. eeeeeK... mine must be the size of a walnut!

Don’t believe everything you see online…
Look carefully and it appears the lightning bolt is much further from the camera than the giraffe. A cloud weighing a million tonnes, how big is that cloud, they are variable? The Earth’s rotation is slowing down incredibly slowly, https://www.jpl.nasa.gov/news/earths-daily-rotation-slowing. Your brain is not “eating “ itself, brain cells are just dying as you get older.

Sage advice, though I think the bit about the Earth's spin is correct - the moon is moving away, so it's a conservation of angular momentum thingy.
EDIT - interesting first few paragraphs on winkypedia:
Earth's rotation - Wikipedia

You mean that Nigerian Prince isn't going to send me £100million if I give him my bank details???

The blah about the giraffe originated from the rag Daily Mail, this certainly supports your claim that this is nonsense 🤣

If iron was less dense than rock, there would be no life on Earth (at least not as we know it, Jim...
We'd have a planet with an iron crust over a rocky core. Iron being a good conductor of heat would mean that the stone core would have cooled a lot more that the existing iron one. Plus, crucially, no molten iron core would mean no magnetic field, meaning no protection from the solar wind and cosmic rays, so nothing to breathe and massive doses of radiation.

You can't be more dense than Rock. I've seen his films!

Talk of elements makes me think about the fact physicists shaven’t solved the quantum gravity problem.
Two theories about our universe that have yet to be disproved, but at the same time cannot exist together 🤯

You might like to look at this from MiT, research into how quantum physics and General Relativity work together.

Thanks, some cool ideas in there.You might like to look at this from MiT, research into how quantum physics and General Relativity work together.

Might be worth highlighting it finishes with this statement: "there is still no clear fundamental description of the theory that works in all situations, and the set of four-dimensional solutions"

Trust us Sam - the two are definitely not reconciled. It's the sort of thing that would probably make the main news.

It's the biggest challenge in physics, as far as I understand it. There's lots of work going on - science never rests.

Saturn's rings are 170,000 miles across, but for the most part only 40 feet thick. If you scaled a piece of A4 paper up to the same width, the paper would be thicker than the rings are. (Philip Plait's Under Alien Skies)
