CERN researchers trace particle movements, Big Bang appearance is reproduced with CG

It is well known that the big bang is about the big explosion that happened at the beginning of the universe, but I can not actually see what the explosion was exactly.

For images to be posted below,CERN (European Nuclear Research Organization)Researchers modeled how elementary particles showed movement during the explosion of the Big Bang by causing atomic size lead ions to collide with each other.

In the experiment,absolute temperatureIn a space of minus 273 degrees Celsius which is almost close to, we collide lead ions with each other and trace the movement of that particle.



The linearity of the image is a trajectory showing how the collided particles moved, and the line color shows the heat intensity of each particle in the same color as the flame hue. In this image, the central red is strong and the yellow is weak.


According to a CERN spokesperson, "If you collide two lead ions,Pi mesonWill be released. We can not see the particles themselves, but we can see the trajectory. "



In addition, the spokesperson said "Subatomic particleAre the basic building blocks of atoms, so from these experiments we can know more about what the universe is made from and how it started. "
