2. You Could Feasibly Eat 3000 Year Old Honey.


It might be hard to bee-lieve but the 3,000-year-old sweet treat found in pyramids is still edible.

The secret behind honey’s eternal shelf life is a range of factors. Hydrogen peroxide, acidity and lack of water (hygroscopic) work together to make this sticky substance last forever.

3. A photon takes thousands of years to travel from the core of the sun to the surface, but only 8 minutes to travel the rest of the way to earth.


The 8-minute travel time to Earth by sunlight hides a thousand-year journey that actually began in the core.

4. Almost all of ordinary matter (99.99% of it) is empty space. If you took out all of the space in our atoms, the entire human race (7 billion+) would fit into the volume of a sugar cube



Size of an atom is governed by the average location of its electrons: how much space there is between the nucleus and the atom’s amorphous outer shell. Nuclei are around 100,000 times smaller than the atoms they’re housed in. If the nucleus were the size of a peanut, the atom would be about the size of a baseball stadium. If we lost all the dead space inside our atoms, we would each be able to fit into a particle of dust, and the entire human species would fit into the volume of a sugar cube.

5. If you unravelled all of the DNA in your body, it would span 34 billion miles, reaching to Pluto (2.66 billion miles away) and back … 13 times.



DNA is supercoiled using enzymes so that it takes up less space. Try holding a piece of string at one end, and twisting the other. As you add twist, the string creates coils of coils; and eventually, coils of coils of coils. Your DNA is arranged as a coil of coils of coils of coils of coils! This allows the 3 billion base pairs in each cell to fit into a space just 6 microns across.
