- How close to the Big Bang can modern particle accelerators get?
How many nanoseconds after the Big Bang was its energy density that achievable in modern particle accelerators?
jeremyfiennes said:From fig.11 I see that temperature is given in baryon-Mev, which is a unit of energy, rather than degrees C. So they are different ways of expressing the same thing?
The Big Bang Energy Density refers to the amount of energy present in the universe at the time of the Big Bang. It is estimated to be incredibly high, around 10^29 grams per cubic centimeter.
Modern particle accelerators allow us to recreate the extreme conditions of the early universe, including the high energy densities present during the Big Bang. By colliding particles at high speeds, we can study the fundamental particles and forces that make up our universe.
One major achievement is the discovery of the Higgs boson, a fundamental particle that gives other particles their mass. This discovery was made using the Large Hadron Collider, the largest and most powerful particle accelerator in the world. Other achievements include studying the behavior of matter at extreme temperatures and densities, and uncovering new particles and forces.
One challenge is the high cost and technical complexity of building and operating large particle accelerators. Another challenge is creating and controlling the extreme conditions needed to study the early universe, such as very high temperatures and energy densities. Additionally, interpreting the vast amounts of data produced by particle collisions can be a challenge.
Scientists are constantly working on improving and building new particle accelerators to push the boundaries of our understanding of the early universe. This includes plans for even larger and more powerful accelerators, as well as developing new technologies and techniques for studying particle collisions. Additionally, advancements in computing and data analysis may help us better interpret the data from these experiments.
