Welcome to the newest edition of The Why. “Why didn’t the universe collapse after the Big Bang?” you ask? Good question. Timely too. (Besides, it sure beats answering the question: “Why does my great grandma smell like that?”)
If you had Physics in college you might think that something is wrong. After all, if you consider the principles of physics, the universe should not be here. Robin Burks a “GEEK” writer for Tech Times concurs.
Burks says: “Theories dictate that because the universe was so unstable after the Big Bang, it should have quickly collapsed.” She elaborates: “In 2012, (scientists) discovered the . . . Higgs particle . . . an elementary particle in the standard model of particle physics. After studying the Higgs, physicists determined that the Big Bang, which resulted in the universe expanding at an unprecedented rate, should have made it so unstable that it collapsed.”
Which brings us to our question of the day: Why didn’t the universe collapse after the Big Bang? According to recent research, the answer is: gravity. Some physicists at the University of Helsinki in Finland the Imperial College London in England and the University of Copenhagen in Denmark, claim that gravity provided the glue to hold the universe together when it was initially unstable.
As you may already know, gravity is a part of Einstein’s “theory of relativity.” Gravity is essentially a consequence of spacetime curvature. These scientists think this is what kept the universe intact during the rapid expansion following the Big Bang. (Heavy stuff, huh? Maybe that’s why a ton of folks prefer to go with God created the universe and be done with it.)
At any rate, these physicists learned that it would take but “a small interaction between gravity and the Higgs” to hold the universe in one piece and keep it from collapsing. Mind you, with scientists, every way of proving themselves wrong has to be exhausted first so they say the theory still requires additional examination.
Until they do some more work with the LIGO (Laser Interferometer Gravitational-Wave Observatory) detectors next year, you’ll have to be happy with the answer: “gravity.” Professor Arttu Rajantie, from the Department of Physics at Imperial College London concluded:
“Our aim is to measure the interaction between gravity and the Higgs field using cosmological data. If we are able to do that, we will have supplied the last unknown number in the Standard Model of particle physics and be closer to answering fundamental questions about how we are all here.”
Why didn’t the universe collapse after the Big Bang? Now you know.
