The origin of the Universe begins with the Big Bang, but how the super-explosion ignited has long been a mystery ̵

1; so far.


In a new paper appearing today in Science Science researchers detail the mechanisms that can cause an explosion, which is key to the models scientists use to understand the origin of the universe.

"We have defined the critical criteria by which we can activate a flame to generate our own turbulence, spontaneously accelerate and go into detonation," says Karim Ahmed, Assistant Professor at the UCF Department of Mechanical and Space Engineering and co-author

"We use turbulence to improve the mixing of reactions to the point where it undergoes this violent reaction and essentially results in supernovae that burst stars in simple expression," says Ahmed. k Here, it responds at five times the speed of sound. "

The researcher revealed the criteria for creating a Big Bang explosion while researching methods for hypersonic jet propulsion.

" We study these supersonic propulsion reactions and the resulting we came across this mechanism, which seemed very interesting, "he said. "As we began to dig deeper, we realized that this was related to something as deep as the origin of the universe."

is the application of the correct amount of turbulence and mixing to an unconfined flame until it hardens, at which point the flame begins to burn the energy absorbed, leading to a hypersonic explosion of the Mach 5. Supernatural machine.

The key faster air travel and space and improved energy production, including reactions that generate zero emissions, as all products used in combustion are converted into energy. The discovery was made with the help of a unique turbulent shock tube that allows the creation and analysis of explosions in a closed environment. Ultra-fast lasers and cameras are used to measure explosions and help to identify what factors are needed to get to the point where the flame becomes hypersonic, violent reaction.
