Hemp-Green.com @hempgreenhk Galaxies contain stars, planets and gases. All the visible universe β the Earth, Sun, stars and galaxies, everything that makes βusβ β is made of protons, neutrons and electrons bundled together into atoms. Perhaps one of the most surprising discoveries of the twentieth century was that ordinary matter makes up less than five per cent of the mass of the universe. The rest of the universe appears to be made of a mysterious, invisible substance named dark matter, and a force that repels gravity known as dark energy. The exotic unknown substance named dark matter doesnβt appear to absorb, reο¬ect or emit light, rendering it βinvisibleβ. #hk #hongkong #cbdisolates #thcfree #weimprovelives #universe (at ππππ ππππ) https://www.instagram.com/p/CL6oFGhphii/?igshid=1dyhizeyuc0mt
