universe began with Big Bang, and w scientists have explained how mysterious explosion may have taken place around 13.8 billion years ago. Big Bang ory states that all matter that exists today in universe sprung forth from a single point in an epic explosion. research, published in journal Science, details mechanisms that could cause explosion, which is key for models that scientists use to understand origin of universe.

Big Bang ory explained
"We defined critical criteria where we can drive a flame to self-generate its own turbulence, spontaneously accelerate, and transition into detonation," said Kareem Ahmed, an assistant professor at University of Central Florida in US. He added,"We are using turbulence to enhance mixing of reactions to point where it transitions into this violent reaction and essentially leads to supervas, which is exploding stars in simple terms."
"We are taking a simplified flame to where it's reacting at five times speed of sound," he explained. team uncovered criteria for creating a Big Bang-type explosion while exploring methods for hypersonic jet propulsion.

"We explore se supersonic reactions for propulsion, and as a result of that, we came across this mechanism that looked very interesting," said Ahmad. "When we started to dig deeper, we realised that this is relatable to something as profound as origin of universe," he said in statement.
key is applying right amount of turbulence and mixing to an unconfined flame until it becomes self-perpetuating, at which point flame begins to burn ingested energy leading to a hypersonic -- exceeding speed of sound -- superva explosion.

Methodology used
finding may have applications in faster air and travel, and improved power generation, including reactions that generate zero emissions as all of products used in combustion are converted into energy, researchers said. discovery was made by using a unique turbulent shock tube that allowed explosions to be created and analysed in a contained environment, y said. researchers ted that ultra-high-speed lasers and cameras were used to measure explosions and help indicate what factors were needed to reach point where a flame becomes a hypersonic, violent reaction.
