I wrote down a few facts on my journal that I took from the internet. Unsure if this has been posted before. I'll start with DNA. 

 

Please feel free to correct any inaccuracies. 

 

1. Human adult is made up of around 7,000,000,000,000,000,000,000,000,000 (7 octillion: 7x10 to the 27th) atoms.

 

2. 1 teaspoon of DNA carries instructions for building 350 times the number of humans alive today

 

3. In average life span of a human, DNA is copied 10,000,000,000,000, 000 times (1x10 to the 15th).

More mind-blowing facts:

 

Almost all of ordinary matter (99.9999999% of it) is empty space. If you took out all of the space in our atoms, the entire human race (all 7 billion of us) would fit into the volume of a sugar cube.
 

There might be as many as three sextillion stars in the universe. That’s 3 followed by 23 zeros, or 300,000,000,000,000,000,000,000. That’s more than all of the grains of sand on Earth.
 

Last year, scientists found the most luminous galaxy with light of more than 300 trillions (million million) suns.

Neutron stars spin incredibly quickly and are also incredibly dense. It is estimated, if you could collect a tablespoon of matter from the centre of a neutron star, it would weigh about one billion tons.

 

Our brains are remarkably complex objects with a hundred billion neurons, a quadrillion connections, and we still know very little about how this organic super computer operates.

 

Gliese 436 b is a Neptune-sized exoplanet located about 33 light-years away in the constellation Leo. Astronomers believe that it embodies exotic states of water that causes its surface to be covered in burning ice. The pressure on the planet forces the ice to stay solid, but the extreme surface temperature of 570° F (300° C) superheats the water, causing it to come off as steam.

The speed of sound is 767 mph

Light travels 671,000,000 mph (186,000 miles per second)

 These are somewhat "commonly known" speeds/facts

 

Lesser known is that, while the speed of light is constant, the speed of sound is not. The speed of 767 mph is"through the air". However, sound travels faster in more dense objects. It travels 3,319.6 mph through water, 11,453.1 mph through steel  and a whopping 26,843.2 mph through a diamond.


Lesser known is that the speed of electricity is in between sound and light.  Electricity travels at 6,696,000 miles per hour "through" a copper conductor (the most common way it is transferred)

 

The typical lightning bolt packs 100 million volts.

The average taser emits 50,000 volts.

A spark of static electricity can measure up to 3,000 volts.

Electric eels can produce shocks of 500 volts or more.

That is shocking information :eek:

A lot more than I thought. I think it would take more than 63,000 years just to count the galaxies. That if we think that there is 2 Trillion galaxies.

Years ago (pre-truth)I had a book with pictures of graffiti. Mostly inappropriate but I remember this one:

'If our brains were simpler we would be too stupid to understand them.'

Not that we actually understand them.
