University of Toronto physicists harness neglected properties of light

Harnessing the extra light — new method.


TORONTO, ON (Canada) – University of Toronto (U of T) researchers have demonstrated a way to increase the resolution of microscopes and telescopes beyond long-accepted limitations by tapping into previously neglected properties of light. The method allows observers to distinguish very small or distant objects that are so close together they normally meld into a single blur.

Telescopes and microscopes are great for observing lone subjects. Scientists can precisely detect and measure a single distant star. The longer they observe, the more refined their data becomes.

Brand New Maths Could Finally Explain How Disturbances Propagate Through Space-Time

Posted by in categories: cosmology, mathematics, physics

The Universe as we know it is made up of a continuum of space and time — a space-time fabric that’s curved by massive objects such as stars and black holes, and which dictates the movement of matter.

Thanks to Einstein’s gravitational waves, we know disturbances can propagate through both space and time. But what’s less understood is exactly how that happens when properties of the fabric is continuously shifting.

Hubble image captures the death of a star

Posted by in categories: physics, space

Feb. 3 (UPI) — A new image from the Hubble Space Telescope displays the beauty of a stellar death — in this case, the death of a low-mass star, similar to our sun in size.

Once a red giant, the star is currently in a transitionary phase: It’s on its way to becoming a planetary nebula. The Hubble image reveals the star’s layers of gas and dust being shed and thrown outward. The expelled material, now forming clouds, could eventually form new stars and planets.

Astronomers rarely catch dying red giants in their transitionary phase. It will only be a few thousand years before the star is a pure planetary nebula — a blip in space time.

Study reveals substantial evidence of holographic universe

Posted by in categories: cosmology, holograms, physics

Theoretical physicists and astrophysicists, investigating irregularities in the cosmic microwave background (the ‘afterglow’ of the Big Bang), have found that there is substantial evidence of our universe being a vast and complex hologram. A UK, Canadian and Italian study has provided what researchers believe is the first observational evidence supporting a holographic explanation of the universe. The researchers from the University of Southampton (UK), University of Waterloo (Canada), Perimeter Institute (Canada), INFN, Lecce (Italy) and the University of Salento (Italy) have published their findings in the journal Physical Review Letters.

What Was Our Universe Like Before the Big Bang?

Posted by in categories: cosmology, physics

Theoretical physicists and cosmologists deal with the biggest questions, like “Why are we here?” “When did the universe begin?” and “How?” Another questions that bugs them, and likely has bugged you, is “What happened before the Big Bang?”

Help Me, Obi-Wan! New Hologram Technology Mimics ‘Star Wars’

Posted by in categories: augmented reality, holograms, physics

Princess Leia’s holographic plea in the classic film “Star Wars” inspired researchers to work toward a device that could project real-life sci-fi holograms. Now, the futuristic 3D imaging may be one step closer to reality.

A team of physicists at the Australian National University (ANU) invented a tiny device that creates the highest-quality holographic images ever achieved, the scientists said.

Study lead researcher Lei Wang, a Ph.D. student at the ANU Research School of Physics and Engineering, said he first learned about the concept of holographic imaging from the “Star Wars” movies. However, these futuristic-looking 3D images could be used for more practical ends than sending messages from a galaxy far, far away.

Physicists ‘have substantial evidence’ our universe is a HOLOGRAM

Posted by in categories: holograms, mathematics, physics

The researchers from the University of Southampton, working with colleagues in Canada and Italy, claim there is as much evidence for this theory as for traditional explanations for these irregularities.

A holographic universe, an idea first suggested in the 1990s, is one where all the information, which makes up our 3D ‘reality’is contained in a 2D surface on its boundaries.
