Mercury has the greatest temperature swing of all the planets in the solar system, ranging from minus 184 degrees to 427 degrees Celsius.
Luv things to do with space etc cheers for that one :35: It is just unimaginable for me to think about that swing in temperature, fook me when it drops a few degree's i run for me jumpers, i don't think we willbe going to Mercury in the future somehow :10:
I love spacey facts. Looking at the stars is a time machine, the light you see is from the past, not the present. The light from the Sun takes 8 minutes to reach us from it's source, everything you see happens in the past, your brain is behind in computing information all the time.
This is from an interesting article I read a while back, explaining how you won't experience your own death if it happens suddenly, and you will quite literally not know what hit you -
"To get an appreciation of the slowness of human perception, Eagleman says it's helpful to compare it to the speed of mechanical devices. Take the anatomy of a car accident for example. It takes as long as 150 to 300 milliseconds (ms) to be aware of a collision after it happens. Other neuroscientists think it can take as much as 500 ms."
Now this might not sound like a lot of time, but think of what happens during a car accident. At the 1 ms mark, the car's pressure sensor detects a collision, and at 8.5 ms the airbag system fires. At the 15 ms mark, the car starts to absorb the impact to a significant degree. It's not until the 17 ms mark that the occupant starts to make contact with the airbag, with the maximum force of the collision reaching its apex at the 30 ms point. At the 50 ms mark, the safety cell begins to rebound, and after 70 ms the passenger moves back towards the middle of car — the point at which crash-test engineers declare the event as "complete.
And then, around the 150 to 300 ms mark, the occupant finally becomes aware of the collision.
That's assuming of course that an airbag was deployed or that the occupant was wearing a seatbelt. Otherwise, the person wouldn't have known that they were even in a car accident.
Which, if the accident was fatal, is not necessarily a bad thing."
