Runaway Universe | How Big is the Universe? By Brent Tully Posted 11.11.00 NOVA How big is the universe? Could it be infinitely large? If the universe has an edge, what is beyond the edge? Our experience of the everyday world does not prepare us to grasp the concept of an infinite universe. There are billions of galaxies in the visible universe. The Visible Universe There is an edge to what we are able to see and could ever possibly see in the universe. This horizon describes the visible universe—a region some 28 billion light years in diameter. While we can never directly "see" the whole of the universe or glimpse its farthest horizons, we can discover how it is behaving This view of the universe fits with the currently popular idea that the universe began with a vast expansion of size. If this grand idea is correct, then the universe is larger than we ever could have imagined. The universe began with a vast explosion that generated space and time—a hard thing to visualize.

Is the Universe a Holographic Reality? - Global One TV The Universe as a Hologram by Michael Talbot Does Objective Reality Exist, or is the Universe a Phantasm? In 1982 a remarkable event took place. At the University of Paris a research team led by physicist Alain Aspect performed what may turn out to be one of the most important experiments of the 20th century. You did not hear about it on the evening news. Aspect and his team discovered that under certain circumstances subatomic particles such as electrons are able to instantaneously communicate with each other regardless of the distance separating them. University of London physicist David Bohm, for example, believes Aspect's findings imply that objective reality does not exist, that despite its apparent solidity the universe is at heart a phantasm, a gigantic and splendidly detailed hologram. To understand why Bohm makes this startling assertion, one must first understand a little about holograms. This insight suggested to Bohm another way of understanding Aspect's discovery.

Howstuffworks "How Holograms Work" ­If you want to see a hologram, you don't have to look much farther than your wallet. Th­ere are holograms on most driver's licenses, ID cards and credit cards. If you're not old enough to drive or use credit, you can still find holograms around your home. They're part of CD, DVD and software packaging, as well as just about everything sold as "official merchandise." ­Unfortunately, these holograms -- which exist to make forgery more difficult -- aren't very impressive. You can see changes in colors and shapes when you move them back and forth, but they usually just look like sparkly pictures or smears of color. ­On the other hand, large-scale holograms, illuminated with lasers or displayed in a darkened room with carefully directed lighting, are incredible. If you look at these holograms from different angles, you see objects from different perspectives, just like you would if you were looking at a real object. Holograms have other surprising traits as well.

Todd's Intro to Quantum Mechanics Sonoluminescence Single-bubble sonoluminescence - A single, cavitating bubble. Video of synthetic wound cavity collapsing creating sonoluminescence. Long exposure image of multi-bubble sonoluminescence created by a high-intensity ultrasonic horn immersed in a beaker of liquid History[edit] The sonoluminescence effect was first discovered at the University of Cologne in 1934 as a result of work on sonar. In 1989 an experimental advance was introduced by Felipe Gaitan and Lawrence Crum, who produced stable single-bubble sonoluminescence (SBSL). Properties[edit] Sonoluminescence can occur when a sound wave of sufficient intensity induces a gaseous cavity within a liquid to collapse quickly. Some facts about sonoluminescence: Rayleigh–Plesset equation[edit] The dynamics of the motion of the bubble is characterized to a first approximation by the Rayleigh-Plesset equation (named after Lord Rayleigh and Milton Plesset): Mechanism of phenomenon[edit] In 2002, M. Other proposals[edit] Quantum explanations[edit] [edit]

The Museum of Unworkable Devices Physics Gallery - StumbleUpon Perpetual motion machine inventors do have principles. Unfortunately the physical principles they assume are often ones not obeyed by nature. Let's examine just a few. The principle of unlimited possibility. Anything is possible Inventors assume that since we haven't looked at every part of the universe nor have we looked at all possible mechanisms or phenomena, we can't rule out anything. Those who think this way are much like the child who puts two blocks in a box, closes the box, shakes it, then opens it, hoping to find three blocks inside. The "heavier on one side" seduction. The most naive level of perpetual motion seduction is the notion that if a system has more mass on one side of the axle, then that side must swing downward. We can test its stability by turning the wheel to any position whatever. The earliest unbalanced wheel of Bhaskara underwent countless modifications and embellishments over centuries. The situation is worse than that. But this isn't a valid test.
