Einstein's theory of relativity gives us a smooth and organized way to think about the universe, like a well-arranged blueprint. On the other hand, quantum physics is more like a jumble of noise and unpredictability, making it hard to fit into that neat blueprint. So, how do we make sense of these different pictures and create a clear understanding of how everything fits together in space and time? Well, it turns out that using (quantum) computer science can help us bridge the gap. Scientists have found that our universe seems to cleverly blend gravity and quantum physics, much like managing noisy data on a computer. This blending helps to keep the spacetime continuum intact as much as possible, using a technique called quantum error correction. This discovery helps us gain a better understanding of black holes. Imagine the surface of a black hole acting like a super-smart computer, simulating what's happening inside. By studying how information moves around inside a black hole, we can learn a lot about how our universe is put together and how information is stored within it.

Life possesses a superpower: the ability to seemingly defy the second law of thermodynamics – the unstoppable rise of entropy. From skyscrapers to poetry, life can evolve and create ever-more complex structures, apparently bringing order out of chaos and challenging the universe's entropy machine. However, we will discover that this remarkable feat is not exclusive to life; it can be found elsewhere in nature. From the swirling complexity of tornadoes to the orderly patterns of crystals, nature exhibits a knack for generating order amidst chaos. Interestingly, even self-duplication and evolution may be viewed as ultimately contributing to entropy. In this episode, we'll explore how, despite the apparent creation of order, the universe's entropy machine ultimately prevails. Counterintuitively, life itself may be viewed as an entropy machine in the grand cosmic narrative. Join us at Discord Discord: ⁠⁠⁠⁠⁠⁠⁠⁠https://discord.gg/qPuVBXNZ

What keeps our nuclei stuck together? It's the somewhat less well-known particle, gluon. They reason we don't see it very much is because it is doing a superb job at jail-keeping its nuclear constituents. Gluons' peculiar abilities to keep things together may also provide us unlimited clean energy in the future. In this episode we'll describe just how the gluon manages to do its jobs and its importance for our Universe.

What is the one particle that cannot be stopped? The answer would have to be the graviton. While the graviton interacts with everything, it also passes through everything mostly unscathed. This unique property makes graviton one of the greatest messengers of the Universe.

The God's particle is a misnomer in particle physics: The Higgs Boson doesn't participate very much in the creation of our Universe. A more proper title for the Higgs Boson would be the Keystone particle, as it is the key that sets the interaction strength and relevant energies in our Universe. This episode we'll explore what that means.

In this special Valentine Day's episode, we’ll introduce what may be considered the loneliest particles in the Universe -- magnetic monopoles, if it exists. Indeed, on this very same day in 1982, Prof. Blas Cabrera uncovered a potential signal for such a lonely wanderer. Unfortunately the findings were never repeated. Still monopoles can be hiding important secrets of nature, and its loneliness may critically impact the structure of our Universe.

In particle physics, particles aren't necessarily the most important object. It turns out, physicists really are interested in the concept of fields, which will be the focus of this episode.

If there's anything that could last forever, it might be fundamental particles. However, even that may not be true. In fact, particles can and do lose their identity over time, and their existence may ultimately be doomed.

It has been widely popularized that our Universe will end in a heat death, where all interesting activities will cease. But is this really what will happen? With the inclusion of quantum physics, it turns out that heat death may not be so deadly after-all. In fact, there can still be interesting interactions after heat death, and in some cases, new universe can even emerge from the remains...

Unlike the ordinary time we experience, time in quantum systems behave rather differently. From unitarity to quantum recurrence, we explore just how weird quantum times can be, and how our macroscopic notion of time can merge from such a drastically different notion of quantum time.
