If you go within 4 million miles of the sun's surface, you need to be moving fast to achieve orbit. Otherwise the intense gravity of the sun you pull you down. The speed is to stop the probe cascading down to the surface of the sun.

Fastest Spacecraft
According to NASA, the fastest spacecraft ever made is the Parker solar probe going very close around the sun on a highly elliptical orbit. It is traveling 430,000 miles per hour, over a million kilometres per hour. There is a shield on it made of carbon foam that is stopping the spacecraft from melting in the sun's intense heat, but it is very close to the star.

London Underground
The Metro rail system in London is largest in the world when the overground network is also considered.
The standard tube network alone consists is of 402 km of railroad. This makes it the 3rd largest in the world.
There is also a large overground network throughout London.
There are many instances when a street will have two train stations on it with a 5 to 10 minutes walk between them; Places like frogmore and Eastcoat.
Plus there are trams and lite robotic trains(DLR). London is so crammed with trains that there is always a station nearby.

Draw on Command
Google's Gemini artificial intelligence system can now draw on command. I asked it myself to draw and octopus playing pool.
Just like many other ai systems it will read your command and draw a unique image in seconds. It is hard to tell what is more amazing, the ai understanding what you're asking of it, or the speed of it creating something for you.
Google's Gemini ai is free to download and use and can replace your Google assistant. You can then say "hey Google draw a tree in space" or something like that.

Earth Perspective
If Earth was an Orange the atmosphere would be the peel. The maximum extent of the Earth's atmosphere is 96km, but the earth is 12,000 km wide. Most large jet airliners cruise at about 11 to 12 km above sea level, a small fraction of the earth's atmosphere.
If you thought there is more than 1% composition of carbon dioxide you would be wrong. Carbon dioxide comprises less than half a percent. There is more Argon in the atmosphere than carbon dioxide at roughly 1%.

Birthday Paradox
It is possible to be born before someone but still be younger than they are.
If you were born in London England at 1:00 AM and your friend in America was born 2 hours after you, their records would show they're a day older than you. This is because they live in a previous time zone that is in the previous day. At 1:00 Am it is still 7 or 8 pm the previous day, even at 3:00 am UK time it is still the evening the previous day in America.
This paradox gets worse if your born on the 1st of January at 1:00 am because your American friend's records would show they're born a different year to you as well.

Neutrinos
Billions of particles are passing through your body at this moment and throughout your life. They're called Neutrinos and they have almost no mass and don't interact much with matter.
They're thought to be created by the nuclear fusion reactions inside stars and cosmic events. They can be detected but only a small number of them and the detector needs to be very large.

British Flag
It you mixed all the colours of the United Kingdom of Great Britain's flag together, you would get a bright purple colour.
A similar affect could be achieved if the flag was spun around at a curtain speed, a red circle would still be left in the middle.

Premonition of Disaster
Man called Tom Horn claimed to have received a vision of the future, a disaster that would cause the death of millions of people. He claimed the flyby of asteroid apophysis in the year 2029 would actually be a strike from the asteroid.
According to media interviews, he has a significant track record of accurate visions. He correctly predicted the resignation of pope Benedict. He wrote down the correct date of the popes resignation long before it happened.
Have a look a the video yourself and think about it.

Art
A banana duct-taped to a wall has recently sold as a valuble art installment for five million dollars.
I don't get it myself, perhaps they're selling a story or something like that. It makes me feel better about my pen sketches, I'm not good at drawing but when I see modern abstract art, I feel like my images have more clarity about their message and story.
I won't get the full details of the purchase because I don't want to face legal issues.
