What is the mystery behind the events that triggered the formation of our universe as we know it?
The Big Bang, the colossal explosion that caused the formation of our universe, occurred about 13.7 billion years ago. After that, it took millions of years for the Earth to actually form. Known as the Big Bang theory, this theory was put forward by an astronomer named Georges Lemaître in 1927, but it remains an open question today. What were the early days of the Big Bang like? How did Earth become the planet it is today? What really happened during the Big Bang?
According to the Big Bang theory, the universe began as a single point known as a singularity. The universe stretched and expanded, got bigger and bigger than it is now, and is still expanding a little bit every day, although according to space.com this singularity is based on Albert his Einstein’s general theory of relativity , which may not be entirely true.
Technology that captures it all
Understanding all this is simply not possible without technology and the gadgets that come with it. NASA’s Cosmic Background Explorer satellite and Wilkinson Anisotropy Microwave Probe reported observations of microwave light just 400,000 years after the Big Bang, according to the space agency. According to NASA, the universe was shrouded in darkness for a long time after the first explosion, until the first glimpses of visible and ultraviolet light were seen 100 million years later. This light was captured in data form by another NASA gadget, the Spitzer Space Telescope.
What do the experts say?
Sean Carroll, a theoretical physicist at the California Institute of Technology, said on space.com: It would be wrong because it doesn’t take quantum mechanics into account. And once it reaches its place in the history of the universe, quantum mechanics will certainly become important. ”
The universe expanded to about 100 times its size in a fraction of a second, known as inflation. Alex Filippenko, an astrophysicist at the University of California, Berkeley, told space.com: Before inflation, there were just a few, maybe a little more expansion. Something like inflation was needed to make the universe bigger. ”
