👋 Hey Friends,
welcome back to a new episode of the Sunday Night Sky, the newsletter where we explore and learn about new scientific achievements, astrophysical, mathematical, and physical theories to understand the world around us a little better.
i have recently read "The End of Everything: (Astrophysically Speaking)" by the cosmologist and author Katie Mack who studies and teaches about the cosmos at the North Carolina State University where she especially focuses on dark matter and the concept of Vacuum Decay. In her book she explores the varies possible edings for our beloved cosmos, one of which is vacuum decay. Exactly this concept stroke my eye and we today explore how the hole universe and everything within it could literally vanish each second.
☄️ What is Vacuum Decay?
Vacuum decay is a hypothetical event in which the vacuum of space undergoes a sudden and catastrophic change, leading to the destruction of the entire universe as we know it. In the current model of particle physics, the vacuum of space is not completely empty but contains a field of energy called the Higgs field. The Higgs field is responsible for giving particles mass and is a fundamental part of the Standard Model of particle physics.
In a vacuum decay scenario, the Higgs field would change from its current stable state to a lower-energy state. This change would cause a wave of destruction to propagate at the speed of light, destroying everything in its path. In this scenario, the destruction would be absolute, and nothing could survive.
👩🔬 How Could Vacuum Decay Happen?
Vacuum decay is a hypothetical event, and there is currently no evidence to suggest that it is imminent or even likely to occur. However, physicists have proposed several ways in which vacuum decay could happen.
One possibility is that a particle accelerator could create a high-energy particle that could trigger vacuum decay. Another possibility is that the Higgs field could change state due to a cosmic event, such as a collision between two black holes. Alternatively, vacuum decay could be triggered by a random quantum fluctuation.
💀 What Would the Consequences of Vacuum Decay Be?
The consequences of vacuum decay would be catastrophic. If the vacuum of space were to undergo a sudden change, a wave of destruction would propagate at the speed of light, destroying everything in its path. This destruction would be absolute, and nothing could survive.
If vacuum decay were to occur, it would be the end of the universe as we know it. The laws of physics that govern our universe would cease to exist, and everything we know and love would be destroyed.
Vacuum decay is a hypothetical event that could occur in our universe, leading to the destruction of everything we know and love. While there is currently no evidence to suggest that vacuum decay is imminent, physicists continue to study this phenomenon to better understand the nature of the universe and the laws that govern it. As we continue to explore the mysteries of the universe, we must remain vigilant and prepared for the unexpected, no matter how unlikely it may seem.

The true nature of e (Euler's number)
What is e, what is a derivative and why are exponentials proportional to their own derivative? We find the answers to these question by finding visual and algebraic evidence in order to gain more mathematical intuition for any problem. Dive down the roots and beauty of calculus and learn what it has to do with 2.7182...
✍️ Quote of the week
"The bad news is that this consistent picture of the Standard Model also tells us that our Higgs vacuum—the perfectly balanced set of laws that govern the physical world—is not stable."
