Astronomers agree: Universe is nearly 14 billion years old

Posted by in categories: cosmology, physics

From an observatory high above Chile’s Atacama Desert, astronomers have taken a new look at the oldest light in the universe.

Their observations, plus a bit of cosmic geometry, suggest that the universe is 13.77 billion years old – give or take 40 million years. A Cornell researcher co-authored one of two papers about the findings, which add a fresh twist to an ongoing debate in the astrophysics community.

The new estimate, using data gathered at the National Science Foundation’s Atacama Cosmology Telescope (ACT), matches the one provided by the standard model of the universe, as well as measurements of the same light made by the European Space Agency’s Planck satellite, which measured remnants of the Big Bang from 2009 to ’13.

Engineers Are 3D-Printing a Nuclear Reactor

OEC just started 3D printing classes last year.


It sounds bizarre — but could help the nuclear industry skip decades of rote experimentation.

Episode 31 — Interstellar Propulsion — What We Need to Make Star Trek Real

Posted by in categories: physics, space travel

Will humanity ever travel to the stars? This is a question for the ages and it remains as open as a deserted stretch of interstate highway. To answer this question, we need an international scientifically-based effort that can chip away at the physics needed to make Star Trek real. Please have a listen to this episode with Guest Marc Millis. Well worth your time.


Propulsion physicist Marc Millis talks about the prospects for fast, efficient interstellar travel. Millis was head of NASA’s Breakthrough Propulsion Program at Glenn Research Center outside Cleveland for years beginning in the mid-1990s. We discuss why the problem of traveling to the stars is so difficult and what would need to happen to help such dreams become a reality. It’s a lively and irreverent discussion!

Time travel is theoretically possible, new calculations show. But that doesn’t mean you could change the past

Posted by in categories: physics, time travel

Time travel is theoretically possible according to the laws of physics, a study says. But time-travelers couldn’t alter the past in a measurable way.

Making Money in a Futuristic World (Jobs and Future Business Ideas)

Posted by in categories: business, economics, Elon Musk, employment, physics, robotics/AI, space

In the not so distant future you could be making money from home by controlling robots, robots that are in another country. Or there will be products, such as a self driving Tesla car, that can go out and earn money on their own.

This video takes a look at the futuristic ways people will be earning money. From telepresence jobs and future business ideas, to new space businesses, and even how people will be storing their money — moving away from cash and credit cards to using chips that are in their bodies.

All Dark Matter in the Universe Could Be Primordial Black Holes – Formed From the Collapse of Baby Universes Soon After the Big Bang

Posted by in categories: cosmology, physics

The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) is home to many interdisciplinary projects which benefit from the synergy of a wide range of expertise available at the institute. One such project is the study of black holes that could have formed in the early universe, before stars and galaxies were born.

Such primordial black holes (PBHs) could account for all or part of dark matter, be responsible for some of the observed gravitational waves signals, and seed supermassive black holes found in the center of our Galaxy and other galaxies. They could also play a role in the synthesis of heavy elements when they collide with neutron stars and destroy them, releasing neutron-rich material.

In particular, there is an exciting possibility that the mysterious dark matter, which accounts for most of the matter in the universe, is composed of primordial black holes. The 2020 Nobel Prize in physics was awarded to a theorist, Roger Penrose, and two astronomers, Reinhard Genzel and Andrea Ghez, for their discoveries that confirmed the existence of black holes. Since black holes are known to exist in nature, they make a very appealing candidate for dark matter.

New supercluster discovered by astronomers

Posted by in categories: physics, space

Containing various structures with a range of masses, from massive and dense clusters of galaxies to low-density bridges, filaments and sheets of matter, superclusters are among the largest structures in the known universe. Finding and investigating superclusters in detail could be essential in order to improve our understanding of the formation and evolution of large cosmic filaments.

Now, a group of astronomers led by Vittorio Ghirardini of the Max Planck Institute for Extraterrestrial Physics in Garching, Germany, reports the discovery of a new supercluster. The structure was identified by the eFEDS survey during its Performance Verification (PV) phase.

Consciousness: Redefining the Mind-Body Problem

Posted by in categories: neuroscience, physics

Consciousness is fundamental, pre-exists our Universe and manifests in everything that we think of as real. A brain, as important as it seems, is nothing more than the way that non-local consciousness operates at an “avatar” level during a lifetime. The evidence that all of this is true is consistent and overwhelming. But mainstream science is still bound by the centuries-old “materialist dogma” and stuck with the “hard problem” of consciousness. ​If we assume that consciousness doesn’t arise from the brain activity, as some neuroscientists still presume to be true, where does it come from? #consciousness #mind #self #theology #physics


Discussion of the hard problem of consciousness with certain solutions in phenomenology, possibilities of mind-uploading and implications…

CERN Physicists Set Bounds on Mass of Hypothetical Leptoquarks

Posted by in category: physics

Physicists from the CMS (Compact Muon Solenoid) Collaboration at CERN’s Large Hadron Collider (LHC) report the results of a new search for leptoquarks produced singly and in pairs in proton-proton collisions.
