[b][i]SCIENCE TO SUPPORT A SOUL[/i][/b]
When we die, by the nihilist or atheistic belief, we become nothing. Nothingness, though, in physics is not bound by our physical laws and can create energy from nothing as seen with Hawking Radiation. Such energy may manifest itself in ways such as creating a new universe (Big Bang?), star formation, or the creation of a spirit.
We do not, by science's general consensus, have souls while alive, but there is a possibility of dying and having a soul be formed from the nothingness. Such cases could be manipulated by emotional energies or such. Further evidence can be found in the infamous 21 Grams experiment or by an interesting phenomenon: http://imgur.com/ygs5tMV

I feel like the human "soul" is really just a cloud of electromagnetic energy. The only info i have supporting this is when you put a headphone jack up to your skin on a speaker system it puts up a little bit of static. The system has to be plugged in.
But the body has a slight electric current to it. Bot sure why, I'm not super smart.
The electromagnetic field around our bodies is most likely caused by the iron in our blood moving around each other and ionising
But idk the exact answer either
