How Would Guns Work In Space?

As a follow up to my Science of Infinite Warfare video I address the scientific and engineering problems posed by firearms in space. Regular guns will fire in space, but they're likely to be less reliable unless built with vacuum operation in mind.

Instantaneous welding and lubrication evaporation; something to think about when using unprepped firearms in space.

The most mysterious star in the universe | Tabetha Boyajian

Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing celestial object, a colleague suggested something unusual: Could it be an alien-built megastructure? Such an extraordinary idea would require extraordinary evidence. In this talk, Boyajian gives us a look at how scientists search for and test hypotheses when faced with the unknown.

Batteries are heavier than air, or at least lift.

Why would Travellers be interested in other air transport than air/rafts? Because they're going to be far more cheaper, especially if they didn't bring along one of their own.

Not to mention could be based on what is available at the TL level. Or perhaps the atmosphere of the planet is toxic and they don't have a sealed air/raft so need to use something more specialized.

Even at higher technological levels, I think that economics may continue to drive this.

I'm going to bet that bicycles will still be used.

The All Terrain Vehicle could have options.
One of my good friends from College got his PhD doing some of the initial research into this stuff for aerospace applications! :) Think Ailerons and Speed Breaks without moving parts... I figure that is pretty standard on a Traveller ship. It doesn't change the shape of the ship, but provides very reliable aerodynamic surfaces - especially useful when they don't get used that often, such as on a starship
My friends call me Richard.

Self-sealing would be the obvious application.

An advanced variant would be pop up aerofins and increased streamlining, as the hull heats up as it hits an atmosphere.

Bill Gates' Terrapower Project And The Traveling Wave Reactor | Answers With Joe

Bill Gates has become one of the most powerful philanthropists in the world through the Bill and Melinda Gates foundation, and one of the projects he's supported is a company called Terrapower, which is researching and building a new type of nuclear reactor, known as the Traveling Wave Reactor, that could provide 80% of our energy needs for the next 1000 years.

Here's a new type of non-lethal weapon that I could see being updated for Traveller https://www.chicagotribune.com/suburbs/ ... mpm3K4gnF8 At TL12, I can see longer range, and some form of memory alloy or whatever that more fully wraps the target. Anyone feel like writing stats for this?

MOOSE

... originally an acronym for Man Out Of Space Easiest but later changed to the more professional-sounding Manned Orbital Operations Safety Equipment, was a proposed emergency "bail-out" system capable of bringing a single astronaut safely down from Earth orbit to the planet's surface.
The design was proposed by General Electric in the early 1960s. The system was quite compact, weighing 200 lb (91 kg) and fitting inside a suitcase-sized container. It consisted of a small twin-nozzle rocket motor sufficient to deorbit the astronaut, a PET film bag 6 ft (1.8 m) long with a flexible 0.25 in (6.4 mm) ablative heat shield on the back, two pressurized canisters to fill it with polyurethane foam, a parachute, radio equipment and a survival kit.
The astronaut would leave the vehicle in a space suit, climb inside the plastic bag, and then fill it with foam. The bag had the shape of a blunt cone, with the astronaut embedded in its base facing outward. The rocket pack would protrude from the bag and be used to slow the astronaut's orbital speed enough so that they would reenter Earth's atmosphere, and the foam-filled bag would act as insulation during the subsequent aerobraking. Finally, once the astronaut had descended to 30,000 ft (9.1 km) where the air was sufficiently dense, the parachute would automatically deploy and slow the astronaut's fall to 17 mph (7.6 m/s). The foam heat shield would serve a final role as cushioning when the astronaut touched down and as a flotation device should they land on water. The radio beacon would guide rescuers.
General Electric performed preliminary testing on some of the components of the MOOSE system, including flying samples of heat shield material on a Mercury mission, inflating a foam-filled bag with a human subject embedded inside, and test-dropping dummies in MOOSE foam shields short distances. U.S. Air Force Capt. Joe Kittinger's historic freefall from a balloon at 103,000 ft (31,000 m) in August 1960 also helped demonstrate the feasibility of such extreme parachuting. However, the MOOSE system was nonetheless always intended as an extreme emergency measure when no other option for returning an astronaut to Earth existed; falling from orbit protected by nothing more than a spacesuit and a bag of foam was unlikely to ever become a particularly safe—or enticing—maneuver.
Neither NASA nor the U.S. Air Force expressed an interest in the MOOSE system, and so by the end of the 1960s, the program was quietly shelved.

How the Universe Works - Formation of the Solar System And Black Hole - Space Discovery Documentary

Started streaming on Jan 6, 2019

The formation and evolution of the Solar System began 4.6 billion years ago with the gravitational collapse of a small part of a giant molecular cloud. Most of the collapsing mass collected in the center, forming the Sun, while the rest flattened into a protoplanetary disk out of which the planets, moons, asteroids, and other small Solar System bodies formed.

This model, known as the nebular hypothesis was first developed in the 18th century by Emanuel Swedenborg, Immanuel Kant, and Pierre-Simon Laplace. Its subsequent development has interwoven a variety of scientific disciplines including astronomy, physics, geology, and planetary science. Since the dawn of the space age in the 1950s and the discovery of extrasolar planets in the 1990s, the model has been both challenged and refined to account for new observations.

The Solar System has evolved considerably since its initial formation. Many moons have formed from circling discs of gas and dust around their parent planets, while other moons are thought to have formed independently and later been captured by their planets. Still others, such as Earth's Moon, may be the result of giant collisions. Collisions between bodies have occurred continually up to the present day and have been central to the evolution of the Solar System. The positions of the planets might have shifted due to gravitational interactions. This planetary migration is now thought to have been responsible for much of the Solar System's early evolution.

In roughly 5 billion years, the Sun will cool and expand outward to many times its current diameter (becoming a red giant), before casting off its outer layers as a planetary nebula and leaving behind a stellar remnant known as a white dwarf. In the far distant future, the gravity of passing stars will gradually reduce the Sun's retinue of planets. Some planets will be destroyed, others ejected into interstellar space. Ultimately, over the course of tens of billions of years, it is likely that the Sun will be left with none of the original bodies in orbit around it.

Really interesting, the parts that I've managed to watch.

Apparently, Saturn balances out Jupiter, which I think is the reason humanity is still alive.
