Professor Lawrence Krauss: The true size of the universe is unknown.

In this episode of “Free Your Voice,” hosted by Dustin Plantholt and sponsored by Orion Messenger, listeners can expect an enthralling conversation with Professor Lawrence Krauss.

Professor Lawrence Krauss is a renowned theoretical physicist, cosmologist, and best-selling author known for his work on the universe’s origin and the relationship between science and society. He has written several acclaimed books, including ‘The Physics of Star Trek’ and his latest work, ‘The Edge of Knowledge. With a career that spans decades, Professor Krauss has received numerous awards for his contributions to science and science communication, including the prestigious Lilienfeld Prize and the Oersted Medal.

The episode kicks off with Dustin recalling a previous conversation where Professor Krauss stated that the true size of the universe is unknown. Krauss emphasizes that not knowing is the essence of scientific inquiry and a driving force behind the pursuit of knowledge.

Throughout their discussion, Professor Krauss elaborates on the nature of the universe, explaining why it doesn’t necessarily have an edge. He uses the analogy of a closed universe resembling the surface of a sphere, where traveling in one direction might eventually bring you back to your starting point. This idea challenges our common sense and expands our understanding of reality.

The conversation then shifts to the relationship between science and religion. Krauss argues that while religion often assumes answers without questioning, science thrives on the ability to question everything, highlighting a fundamental difference in approach.

Listeners will also hear about the challenges faced by scientists and academics in today’s climate, where certain questions and discussions are deemed off-limits. Professor Krauss shares his concerns about the growing trend of censoring scientific inquiry and the importance of maintaining an open dialogue in academic and public spheres.

As the episode progresses, Professor Krauss touches on some of the wildest theories in physics, including the possibility of multiple universes. He discusses the idea that there could be an infinite number of other universes, each with different physical laws and constants, and how this concept, though seemingly metaphysical, is grounded in scientific theories.

The episode wraps up with a discussion on the nature of belief and evidence. Professor Krauss emphasizes that in science, beliefs are based on likelihoods and evidence rather than absolute truths. He shares his views on phenomena like ghosts and the afterlife, arguing that the lack of empirical evidence makes these concepts highly unlikely.

Key Takeaways:

• The universe may not have an edge, challenging our common sense and expanding our understanding of reality.
• The fundamental difference between science and religion lies in the ability to question everything.
• The importance of maintaining open dialogue and resisting censorship in scientific inquiry.
• The fascinating possibility of multiple universes and how this idea is rooted in scientific theory.
• The scientific approach to belief, emphasizing evidence and likelihoods over absolute truths.
