Humans are (Literally) Made of Stars

stars-humansA new study has revealed to us that over half the atoms that are in our bodies have originated from far beyond our own galaxy.

Well known astronomer Carl Sagan once said “The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of star stuff.”
Turns out he was pretty much on the money.
According to the recent results of a computer simulation, the atoms that make up our human bodies not only came from the core of a star, but from a star that did not originate in our galaxy, rather was from a distant galaxy beyond our reach.
According to scientists, large galaxies like The Milky Way actually amass alot of their matter from ‘neighbouring’ star clusters from distances up to 1 million miles away.
“WE DID NOT REALISE HOW MUCH OF THE MASS IN TODAY’S MILKY WAY-LIKE GALAXIES WAS ACTUALLY ‘STOLEN’ FROM THE WINDS OF OTHER GALAXIES,” SAID STUDY CO-AUTHOR CLAUDE-ANDRE FAUCHER-GIGUERE.
These particles once originated in supernovae, sent flying at incredible speeds through the cosmos by galactic winds – streams of charged up particles which are powered by these massive explosions.
It was initially believed that these winds were not strong enough to send large amounts of matter across the massive distances between neighbouring galaxies, however it seems that those forces are actually much stronger than anyone realised.
While they are hurtling through the galaxy at impressive speeds, the transfer of matter between galaxies is a patient man’s game, with the process taking anywhere between a few hundred million years and 2 billion years.
And yet – here we are, made of stardust.

The Enfield Poltergeist

“There was all kinds of phenomena reported and witnessed by the family, neighbors, police, journalists and investigators in 1977 and 1978. Furniture would move around, seemingly without the aid of human hands; knocking sounds were heard, the sources of which were never found; people were allegedly thrown into the air; Janet was seen levitating above her bed—witnessed by a person outside the house through a window; electrical equipment broke down, with batteries draining inexplicably; teleportation; the list is almost endless.” One of the strangest things about the Enfield case is that the ‘thing’ behind it all seemed to be sentient. In fact, it could use knocks to communicate and audio recordings exist of it ‘speaking through’ Janet with a voice most incongruous to an 11-year-old girl. If I remember correctly, the voice identified itself as a previous occupant of the house: Bill Wilkins, an old man who had died of a brain hemorrhage in a chair downstairs. Posted By: Junio
