Startups, universities, and major companies are vying to commercialize a nuclear fusion reactor.
5 Big Ideas for Making Fusion Power a Reality
by Tom Clynes | IEEE Spectrum
The joke has been around almost as long as the dream: Nuclear fusion energy is 30 years away … and always will be. But now, more than 80 years after Australian physicist Mark Oliphant first observed deuterium atoms fusing and releasing dollops of energy, it may finally be time to update the punch line.
Over the past several years, more than two dozen research groups — impressively staffed and well-funded startups, university programs, and corporate projects — have achieved eye-opening advances in controlled nuclear fusion. They’re building fusion reactors based on radically different designs that challenge the two mainstream approaches, which use either a huge, doughnut-shaped magnetic vessel called a tokamak or enormously powerful lasers.
Detailed computer simulations have found that a cosmic contraction can generate features of the universe that we observe today.
Big Bounce Simulations Challenge the Big Bang

The standard story of the birth of the cosmos goes something like this: Nearly 14 billion years ago, a tremendous amount of energy materialized as if from nowhere.
In a brief moment of rapid expansion, that burst of energy inflated the cosmos like a balloon. The expansion straightened out any large-scale curvature, leading to a geometry that we now describe as flat. Matter also thoroughly mixed together, so that now the cosmos appears largely (though not perfectly) featureless. Here and there, clumps of particles have created galaxies and stars, but these are just minuscule specks on an otherwise unblemished cosmic canvas.
Upcoming NASA mission will search for planets in the Milky Way without their own sun.
Rogue Planets That Float in Space Without Orbiting a Sun Could Outnumber the Stars
by Ohio State University | SciTechDaily
An upcoming NASA mission could find that there are more rogue planets — planets that float in space without orbiting a sun — than there are stars in the Milky Way, a new study theorizes.
“This gives us a window into these worlds that we would otherwise not have,” said Samson Johnson, an astronomy graduate student at The Ohio State University and lead author of the study. “Imagine our little rocky planet just floating freely in space — that’s what this mission will help us find.”
A new space-aged propeller plane could overtake business jets at a fraction of the running costs. California-based Otto Aviation claims its prototype Celera 500L can cruise at 450 mph, with a continental range of 4,500 miles. But the most striking boast is an environmentally-friendly fuel efficiency between 18 and 25 miles per US gallon (mpg), comparable to a large car. By comparison, a Bombardier Learjet 60 manages 2.5 mpg while cruising at 500 mph, giving a range of around 2,700 miles.

Some Stars Could Support as Many as 7 Habitable Planets
by Matt Williams | Universe Today
In recent decades, over 4,000 extrasolar planets have been confirmed beyond our Solar System. With so many planets available for study, astronomers have learned a great deal about the types of planets that exist out there and what kind of conditions are prevalent. For instance, they have been able to get a better idea of just how common habitable planets are (at least by our standards).
As it turns out, a surprisingly high number of planets out there could support life. That is the conclusion reached by a team of astronomers and planetary scientists who conducted a study of the possible sizes of habitable zones (HZ) based on stellar classification. After considering how many planets could stably orbit within them, they came to the conclusion that stars with no Jupiter-sized gas giants can have as many as seven habitable planets!
Russian space industry giant Energia is involved in the production of everything from rockets and satellites to space stations and ballistic missiles, and is the prime mover behind the current Russian manned spaceflight programs. Korolev Rocket & Space Corporation Energia has created and patented a means to fly cosmonauts to the Moon and back without an expensive new heavy-launch rocket.

Jeff Rense and Frank Joseph talk about the mysteries of the Tunguska event. This was a very large mid-air explosion that occurred on June 30, 1908 over Siberia. It flattened millions of trees over an area of about 2,000 square kilometers and had an estimated force of about 10 to 30 megatons of TNT. Jeff and Frank discuss the bizarre aspects of this event and speculate about what might have caused it.
Asteroid Impact, Not Volcanic Activity, Killed the Dinosaurs, Study Finds

An asteroid impact, not volcanic activity, killed the dinosaurs, a new study finds.
For decades, scientists have gone back and forth over exactly what caused a mass extinction event 66 million years ago, which destroyed about 75% of all life on Earth, including all of the large dinosaurs. Some have thought that volcanic activity could be to blame, but one new study shows that a giant asteroid impact was the prime culprit.
How many technological developments are in existence that we don’t know about?
US Gov Grants Patents For An Anti-Gravity Craft That Alters The Space-Time Around It

It wasn’t long ago when government agencies and scientists would simply reject even talking about inventions that defy our known laws of physics, but things are changing because science is progressing, and if there’s one thing that’s constant, it’s change. Change is even constant in physics – a great example I like to use is of the prominent physicist Lord Kelvin, who stated in the year 1900, “There is nothing new to be discovered in physics now. All that remains is a more and more precise measurement.” It wasn’t long after this statement when Einstein published his paper on special relativity. Einstein’s theories challenged the accepted framework of knowledge at the time and forced the scientific community to open up to an alternate view of reality.
Far-off alien planets covered in vast oceans might be common in our Milky Way galaxy, scientists find. “Ocean worlds” are terrestrial planets that have significant amounts of water either on their surfaces or in a subsurface sea. In a new study, researchers decided to see how many planets in the Milky Way might fit into the category of “ocean world.” They found that more than a quarter of the 53 exoplanets they studied could potentially be ocean worlds.
Our Milky Way Galaxy May Be Teeming with Ocean Worlds
The star Kepler-160 and its companion KOI-456.04 are more reminiscent of the Sun-Earth system than any previously known exoplanet-star pair. Among the more than 4,000 known exoplanets, KOI-456.04 is something special: less than twice the size of Earth, it orbits a Sun-like star. And it does so with a star-planet distance that could permit planetary surface temperatures conducive to life.

A team of university researchers has found that the probability of discovering Earth-like planets within their early stages of formation is actually higher than previously presumed. New research has indicated that there are many more stars in space that are comparable to our solar system’s sun than expected in the groups of Milky Way stars the study examined, according to a news release on the matter.
