Asteroid Impact, Not Volcanic Activity, Killed the Dinosaurs, Study Finds
by Chelsea Gohd | Space.com
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.
“Mirror Image” of the Earth and Sun Discovered 3000 Light-Years Away
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.
Chances of Finding Young, Earth-Like Planets Higher Than Previously Thought
Quantum Vacuum & Zero Point Energy Access: Is “Free Energy” For All Actually Possible?
by Arjun Walia | Collective Evolution
“Free energy” is a term being tossed around these days, and not one that many within the new energy movement like to use. That’s because it’s not really “free,” or what we perceive “free” to be. It’s not like the power source for generating the energy to run these machines (discussed below in this article) is coming from nowhere.
It’s coming from the quantum vacuum, which would seem to be available for our use in unlimited quantities, given the fact that it’s the invisible “stuff” that makes up our known entire universe, in which could be a sea of universes and dimensions. There is enough to go around.
Proxima b, the Closest Exoplanet We Know, May Be Even More Earth-Like than We Thought

The closest alien planet to our solar system is even more Earth-like than scientists had thought, new observations suggest.
In a new study, an international team of researchers found that Proxima b, which lies just 4.2 light-years from Earth, is just 17% more massive than our planet.
SpaceX Wants to Send People to Mars – Here’s What the Trip Might Look Like
by Meghan Bartels | Space.com
Even as SpaceX prepares to launch astronauts for the first time, the company is sharing its dreams for human spaceflight on a much grander scale: missions to Mars.
SpaceX’s desire to put humans on Mars is nothing new; the company was founded with that goal in mind. But now, the company is testing early versions of the spacecraft it envisions using on such journeys, evaluating potential landing sites and thinking through what a long-term base on the Red Planet might look like many years from now.
About half of all the star systems in the galaxy are made of pairs or triplets of stars. Our solar system features just one star, the Sun, and a host of (relatively) small planets. But it was almost not the case, and Jupiter got right on the edge of becoming the Sun’s smaller sibling.
Jupiter Is so Big That Our Solar System Almost Had Two Suns
The U.S. Space Force is now a reality. Below is the first Space Force recruiting video. It is aimed at people whose purpose is “out of this world.”
“It is technically sound, but there have been issues that have come up on almost every level.”
The Scientists Who Won’t Give Up on the Warp Drive
by Rahul Rao | Gizmodo
For most of us, traveling faster than the cosmic speed limit — the speed of light — is a science-fiction fantasy that breaks the very foundation of modern physics. But in the eyes of an engineering undergrad at the University of Alabama in Huntsville named Joseph Agnew, it’s a theory worthy of study.
The idea first came to Agnew in high school, when he became enamored of the warp drives he saw in Star Trek. “I thought about some of the technology postulated within,” he says, “and wondered what the scientific backing might be.”
An intriguing new theory has been offered for what caused the legendary 1908 Tunguska event. Scientists studying the strange incident, in which a mysterious blast of some kind flattened a whopping 80 million trees over an area of 830 square miles in Siberia, have long suspected that it was caused by a meteor striking the Earth. However, a recently published paper reportedly calls that hypothesis into question and, instead, put forward a rather fantastic alternative explanation. See the following articles:
Permanent magnets akin to those used on refrigerators could speed the development of fusion energy – the same energy produced by the sun and stars. In principle, such magnets can greatly simplify the design and production of fusion devices called stellarators. Most stellarators use a set of complex twisted coils that spiral like stripes on a candy cane to produce magnetic fields that shape and control the plasma that fuels fusion reactions. Refrigerator-like permanent magnets could produce the hard part of these essential fields, allowing simple, non-twisted coils to produce the remaining part in place of the complex coils.
Fusion Energy Solution May Come From Permanent Magnets Like Those on Refrigerator Doors – But Far Stronger
From suborbital flights to orbital missions to trips around the Moon, space tourism is taking off due to technological advancements such as reusable rockets.
