Before this, the Universe is opaque: it is as if a veil has been pulled over it]]> 2021-12-12 17:46:11 UTC https://padlet.com/pablolr2/bxywosoea0a0gjf0/wish/1943002259 pablolr2 https://padlet.com/pablolr2/bxywosoea0a0gjf0/wish/1943011113 Matter clumps together under its own gravity forming the first protogalaxies and within them, the first stars.
Stars and nuclear furnances in which heavier elements such as carbon, oxygen, silicon and iron are formed. Such explosions send material into space ready to be incorporated into future generations of stars and planets.]]> 2021-12-12 17:53:57 UTC https://padlet.com/pablolr2/bxywosoea0a0gjf0/wish/1943011113 pablolr2 https://padlet.com/pablolr2/bxywosoea0a0gjf0/wish/1943018006 Initially, the expansion of the universe decelerated, but few billion years after the Big Bang, the expansion began to acelerate. The aceleration is caused by a mysterious force known as ¨dark energy¨, the nature of which is completely unknown]]> 2021-12-12 18:00:04 UTC https://padlet.com/pablolr2/bxywosoea0a0gjf0/wish/1943018006 pablolr2 https://padlet.com/pablolr2/bxywosoea0a0gjf0/wish/1943037313 The Sun along with its eight planets,including Earth, and all the asteroids, comets and Kuiper Belt objects, such as Pluto, form from the debris left behind by earlier generations of stars]]> 2021-12-12 18:17:12 UTC https://padlet.com/pablolr2/bxywosoea0a0gjf0/wish/1943037313 pablolr2 https://padlet.com/pablolr2/bxywosoea0a0gjf0/wish/1943043937 The first life appears on Earth in the form of simple cells.

Protons decay and black holes evaporate, leaving the Universe to its ultimate face as cold, dead, empty space, containing only radiation which itself too will eventually disperse.]]> 2021-12-12 18:39:13 UTC https://padlet.com/pablolr2/bxywosoea0a0gjf0/wish/1943061760
