Wormholes allow for travel between two distant locations across the space-time continuum. Some scientists believe that extraterrestrial beings may have already used them to travel to Earth in the distant past. The theory of relativity allows for the existence of wormholes or stargates to create shortcuts for interstellar flight; however, exotic matter with negative mass may be required.
The Mercury program represented NASA’s first human spaceflight program, with the aim to see if humans could function effectively in space for a few minutes or hours at a time. NASA’s first seven astronauts, the Mercury 7, were chosen in 1959.
The story of America’s first astronauts is being retold in the TV series “The Right Stuff” on Disney Plus by National Geographic, which premieres Oct. 9 during World Space Week 2020.

Some Planets May Be Better for Life than Earth
by Sara Zaske | WSU News
Earth is not necessarily the best planet in the universe. Researchers have identified two dozen planets outside our solar system that may have conditions more suitable for life than our own. Some of these orbit stars that may be better than even our sun.
A study led by Washington State University scientist Dirk Schulze-Makuch recently published in the journal Astrobiology details characteristics of potential “superhabitable” planets which include those that are older, a little larger, slightly warmer and possibly wetter than Earth. Life could also more easily thrive on planets that circle more slowly changing stars with longer lifespans than our sun.
New research postulates that a particular kind of time travel might actually be possible, according to a recent report. This is because of a middle ground in mathematics that solves a major logical paradox in one model of time travel. This allows local free will within certain constraints.

Did a Solar Flare Sink the Titanic? Study Suggests Space Weather May Have Been Responsible for Tragedy
by Mihika Basu | Meaww.com
The Titanic struck an iceberg in April 1912, and a new study now suggests that space weather, and a solar flare, in particular, may have contributed to the sinking of the ship by interfering with compasses and radio equipment. Mila Zinkova, an independent researcher from the US, explains that ejection of charged particles from the Sun may have caused the crew to make adjustments that led the Titanic along a slightly different course, and this may have put it on the collision course with the iceberg.

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
by Charlie Wood | Quanta Magazine
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.
