New Evidence For The Simulation Hypothesis? Donald Hoffman on The Simulation Argument Subscribe to Science Time: https://www.youtube.com/sciencetime24 Dive deep into a reality that transcends our basic understanding. Is the universe, with its vastness and intricate details, just a simulation? From the pioneering ideas of ancient Greek philosophers like Plato to modern-day scientific breakthroughs, we explore the provocative Simulation Hypothesis. Donald Hoffman, a renowned cognitive psychologist, challenges conventional beliefs about reality, space, and time. Could our experiences, the very laws of physics, and everything around us be the result of advanced computational processes? Quantum mechanics, the double slit experiment, and the recent 2nd law of infodynamics seem to offer tantalizing clues. Join us as we journey through this cosmic conundrum, exploring age-old questions and the cutting-edge scientific insights that hint we might be living in a digital construct. Are we truly witnessing the universe as it is or just through a virtual headset? #simulation #universe #science
Black holes were also known as frozen stars. Basically black holes are stars but with such high density that they exert such powerful gravitational forces that nothing can escape their gravity not even light itself. Subscribe to Science Time for more videos: www.youtube.com/sciencetime24
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the Timaeus of Plato, or Socrates in his reflections on what the Greeks called khôra , or in the Physics of Aristotle in the definition of topos or in the later "geometrical conception of place" as "space qua extension" in the Discourse on Place of the 11th-century Arab polymath Alhazen. Many of these classical philosophical questions were discussed in the Renaissance and then reformulated in the 17th century, particularly during the early development of classical mechanics. In Isaac Newton's view, space was absolute—in the sense that it existed permanently and independently of whether there was any matter in the space. Other natural philosophers, notably Gottfried Leibniz, thought instead that space was in fact a collection of relations between objects, given by their distance and direction from one another. In the 18th century, the philosopher and theologian George Berkeley attempted to refute the "visibility of spatial depth" in his Essay Towards a New Theory of Vision. Later, the metaphysician Immanuel Kant said that the concepts of space and time are not empirical ones derived from experiences of the outside world—they are elements of an already given systematic framework that humans possess and use to structure all experiences. Kant referred to the experience of "space" in his Critique of Pure Reason as being a subjective "pure a priori form of intuition". In the 19th and 20th centuries mathematicians began to examine geometries that are non-Euclidean, in which space is conceived as curved, rather than flat. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space. Experimental tests of general relativity have confirmed that non-Euclidean geometries provide a better model for the shape of space. #sciencetime #space #spaceexploration SUBSCRIBE to our channel "Science Time" https://www.youtube.com/sciencetime24
Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3500 to 3000 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages but was preserved in the Muslim world during the Islamic Golden Age. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe from the 10th to 13th century revived "natural philosophy" which was later transformed by the Scientific Revolution that began in the 16th century as new ideas and discoveries departed from previous Greek conceptions and traditions. The scientific method soon played a greater role in knowledge creation and it was not until the 19th century that many of the institutional and professional features of science began to take shape; along with the changing of "natural philosophy" to "natural science." Modern science is typically divided into three major branches that consist of the natural sciences (e.g., biology, chemistry, and physics), which study nature in the broadest sense; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study abstract concepts. There is disagreement, however, on whether the formal sciences actually constitute a science as they do not rely on empirical evidence. Disciplines that use existing scientific knowledge for practical purposes, such as engineering and medicine, are described as applied sciences. Science is based on research, which is commonly conducted in academic and research institutions as well as in government agencies and companies. The practical impact of scientific research has led to the emergence of science policies that seek to influence the scientific enterprise by prioritizing the development of commercial products, armaments, health care, and environmental protection. #sciencetime #science #sciencevideos SUBSCRIBE to our channel "Science Time" https://www.youtube.com/sciencetime24
The development of full artificial intelligence could spell the end of the human race. We cannot quite know what will happen if a machine exceeds our own intelligence, so we can't know if we'll be infinitely helped by it, or ignored by it and sidelined, or conceivably destroyed by it. This was a quote from the late theoretical physicist, cosmologist, and author, Stephen Hawking. Obviously artificial intelligence and automation in general, is greatly beneficial for society in today's age. And will probably continue to be beneficial in the coming decades. However, if or when intelligent machines becomes strong enough, they will pose a serious threat to humanity. Because a super intelligence is decades if not a century away, it's hard to take this issue very seriously. Or so it would seem. If we stop and think about it, the time-frame as for how long it takes to develop artificial general intelligence is not a compelling argument why we shouldn't be concerned. It is in fact a non sequitur. This response from some quote "skeptics" also comes with an implicit claim. Suppose we figure out it takes a 100 years to develop AGI, to say we shouldn't worry, is to make the latent claim that it takes 99 years or less to make safe AGI. To quote Stephen Hawking again: "So, facing possible futures of incalculable benefits and risks, the experts are surely doing everything possible to ensure the best outcome, right? Wrong. If a superior alien civilization sent us a message saying, 'We'll arrive in a few decades,' would we just reply, 'OK, call us when you get here–we'll leave the lights on?' Probably not–but this is more or less what is happening with AI" It's really a depressing state of affairs for the chances of humanity to survive this existential threat, if we have to convince lay people and some experts alike that we even have a problem. As of 2017, there are about 40 known organizations actively researching AGI. One could argue that the risks involved in the development of AI and ultimately AGI are intrinsic to the creation of intelligent systems that are goal oriented.
