Previously on Thirty Minute Thesis I've explored alternatives to string theory, such as Loop Quantum Gravity. But I realized I hadn't yet explored the basics of string theory itself. So in today's video I ask: "What would It take for String Theory to move beyond the realm of pure math, Into verifiable territory"? Is the fact that many 'discoveries' in string theory revolve around the math of theory itself or already disproven facts about our universe -- such as the fact that AdS/CFT correspondence relies on a negative cosmological constant, in contrast to the observed positive cosmological constant -- already fatal to this once-most-promising of all theories? Or could it be salvaged and, if so, how? Do we need new predictions, or would even a retrodiction suffice?
This episode of Thirty Minute Thesis explores the experimental minimum -- the very basics that any purported theory of everything should aspire to achieve. We discuss the basics of the theory as delightfully explicated by Ed Witten in Physics Today and compare it to other approaches, such as Loop Quantum Gravity and more.
Welcome to another episode of Thirty Minute Thesis -- a solo deep-dive into a fascinating topic in cosmology, physics, or science itself. Today's video explains what String Theory must do in order to prevail as a candidate Theory of Everything.

There is a God equation in mathematics; could there be a God equation in physics? Is Michio Kaku back in control ?
This is the question to which Dr. Michio Kaku has dedicated his life. Dr. Kaku is a theoretical physicist, bestselling author, acclaimed public speaker, renowned futurist, and popularizer of science. As co-founder of String Field Theory, Dr. Kaku carries on Einstein’s quest to unite the four fundamental forces of nature into a single grand unified theory.
In this repost episode of Into the Impossible from 2021, Dr. Kaku and I embark on a quest to find this theory of everything. We discuss artificial intelligence, string theory, God, agnosticism, how to become the next Einstein and one of my favorite books – The God Equation.

Did scientists recently detect evidence for an Anti-Universe, one where time flows backwards? Or is it an overreach into unsupportable hype? I explore the data that led scientists to make claims about ghostly neutrinos that are their own anti-particles. How do scientists interpret data like these and how do physicists reveal the hidden symmetries of nature?
Stange signals were seen in recent years by a NASA-funded radio telescope flown aloft over Antarctica by a giant helium filled balloon. The device, called the Antarctic Impulsive Transient Antenna (ANITA), detects radio signals produced when high-energy particles coming from cosmic sources smash into earth’s atmosphere. Some radio signals waves skim the Earth before being detected by ANITA, and others reflect off the ice. ANITA can tell the difference and some claim their odd behavior are indicative of signals traveling backwards in time. Or are there other interpretatisn? Found out in this video!
Technical write up https://arxiv.org/pdf/1603.05218.pdf
Characteristics of Four Upward-pointing Cosmic-ray-like Events Observed with ANITA
We report on four radio-detected cosmic-ray (CR) or CR-like events observed with the Antarctic Impulsive Transient Antenna (ANITA), a NASA-sponsored long-duration balloon payload. Two of the four were pre- viously identified as stratospheric CR air showers during the ANITA-I flight. A third stratospheric CR was detected during the ANITA-II flight. Here we report on characteristics these three unusual CR events, which develop nearly horizontally, 20-30 km above the surface of the Earth. In addition, we report on a fourth steeply upward-pointing ANITA-I CR-like radio event which has characteristics consistent with a primary that emerged from the surface of the ice. This suggests a possible τ-lepton decay as the origin of this event, but such an interpretation would require significant suppression of the Standard Model τ-neutrino cross section.

My colleague Professor Jorge Hirsch joins me to discuss recent claimed breakthrough in high-temperature superconductors, including claims they work at near ambient pressure and temperture.
Here come cheap magnetic levitating trains, low-loss power distribution, free MRI scanners in every clinic…. Or not?
Watch my solo episode about the controversial claims here: https://youtu.be/hbER0AnwXD4
Since the discovery of superconductors in 1911 by Heike Kamerlingh Onnes, earning the 1913 Nobel Prize in Physics, they have been the subject of much fascination and inquiry. Some of the greatest minds in physics have grappled with how superconductivity works to drive electrical resistance to 0.
The 1972 Nobel prize in Physics was awarded to John Bardeen, Leon Neil Cooper, and John Robert Schrieffer "for their BCS theory of superconductivity. Now the race is on to get the highest temperature superconductor possible; another Nobel Prize was awarded just for getting the temperature up to 35K or -396 Fahrenheit!
Superconducting has remained impractical, until now... Maybe! The HUGE claim: zero resistance, at temperatures up to 65 degrees Fahrenheit. Is it a scientific breakthrough, or is it very probably fraud?

SUMMARY:
Researchers at the University of Rochester claimed that they have discovered a room-temperature superconductor. This would be a major breakthrough, as superconductors are materials that conduct electricity without resistance. This would have a wide range of potential applications, including in power transmission, medical imaging, and quantum computing.
However, the video also discusses some concerns about the validity of the research. The researchers have not yet published their findings in a peer-reviewed journal, and there have been some questions raised about the quality of their data. It is possible that the discovery is a fraud, or that it is not as significant as the researchers claim.
It is too early to say whether the discovery is a breakthrough or a fraud.
Key concepts discussed in the video:
* Superconductors are materials that conduct electricity without resistance.
* Room-temperature superconductors would have a wide range of potential applications, including in power transmission, medical imaging, and quantum computing.
* The researchers at the University of Rochester claim to have discovered a room-temperature superconductor.
* However, there are some concerns about the validity of the research.
* It is too early to say whether the discovery is a breakthrough or a fraud.
