Multi-barrel multi-caliber sidearms seem to be something no one has quite mastered. There are a few that have been modestly successful. but the added complexity and somewhat limited extra utility has kept that type of firearm firmly planted in the "Oddity"

One of the traits that has kept the revolver alive as a self-defense firearm in the age of the Semi-auto is reliability. If you pull the trigger and it doesn't go bang, you just pull the trigger again. well, that and you can generally fire a magnum round out of a revolver with less trouble than firing a high powered round out of a Semi-auto. The 5-6 chamber revolver seems to be the most successful variation. since it has enough shots to deal with one or two targets and can be rapidly reloaded using Speedloaders. when you add more chambers the cylinder has to be enlarged or the walls of the cylinder have to be thinned..which has a definite impact on how powerful the round fired can be.I have had several .22 Long Rifle pistols with more than six cylinders before. they are fun little guns to shoot, the rounds ar not powerful enough to crack even a slightly thinner cylinder wall and the cylinder size isn't unmanageable. but squeezing seven. .38 Special ( around 9mm in diameter)rounds into a cylinder is a bit more tricky.

One advantage some carrying wheel guns sometimes mention: When there is decent lighting, when you face a foe in close proximity, he can *see* the rounds chambered and knows you aren't pointing an empty gun. There's a bit of a visceral reality to staring down the round that might kill you.

When I was firing pistols (.22 LR, .38, .357, 9mm, .45 ACP and a cap and ball revolver), I found revolver ergonomics to make the point-and-shoot even easier than a semi-auto. I guess also I did use longer barrels on the revolvers and I particularly hated the CZ-75 9mm... 9mm rounds were energetic and the weapon was light so I always round the recoil more of an issue. When I shifted to .45 ACP out of a very basic M1911A1 Colt semi-auto, the bigger .45 ACP round felt more like a push than a jump (in terms of recoil) and I shot much better. I can see (just from comfort and natural pointing capabilities) some prefer revolvers. And I can see where some larger rounds still would let you load 5-6 rounds and one good shot could lay out a target.

As you noted, wheel guns have the great feature 'just pull the trigger again'. That's a fast follow up to a failed shot. In a semi-auto, you'll have to pull the slide to eject the round and recock. You often come at least partly off target while doing that whereas the wheel gun user just pulls the trigger again without coming off-target.

And in some instances, some hollowpoints don't work as well in some semi-autos. I think that issue is lesser in revolvers overall. (Not saying you can't find reliable hollow-points for your semi-auto, just may have to be more careful about the ammo source.)

How Would the UNIVERSE LOOK near the SPEED of LIGHT?

Chapters:
0:00 - All light is basically the same
1:44 - Our slow-mo world
2:38 - Doppler effect
4:38 - How colors distort near speed of light
8:09 - Relativistic aberration (searchlight effect)
8:58 - Surprising time and length effects near c
09:05 - Things are NOT as they appear
13:58 - What is really true?

Summary:
All the light that we see are electromagnetic waves. All different wavelengths are equivalent, except that waves of higher frequencies are more energetic. The speed of all these EM waves, however, is the same. It's the maximum speed allowed in the universe.

This speed limit sets the max rate at which information can flow in the universe. This assures that causation is preserved. Einstein showed that the world would look very different as you near this speed. We don’t see this because our terrestrial speeds are very low compared to the speed of light.

What would happen if we traveled closer to the speed of light? Strange things.

When an ambulance approaches you, the wavefront made by its siren gets packed together towards the direction of movement. This causes a higher pitched sound. Similarly, the wavefronts get further apart in the opposite direction. This results in a lower frequency sound. This is the doppler effect.

Something similar happens with light. As seen from earth, most galaxies are redshifted, thus the wavelength is stretched. The galaxies are moving away from us. This is called the relativistic doppler effect, and it happens thanks to relativity. If we built a fast spaceship that traveled near the speed of light, this effect will change how you see the world compared to person who is not moving!

A red traffic light at 25% the speed of light we would be seen as green. If we moved away from the red light at 25% the speed of light, we wouldn't see it at all because it would be infrared, something our eyes can't see.

This also means that infrared light that we currently can't see in the cosmos would become visible in the front window of our spaceship.
Likewise, natural high energy ultraviolet light which is also invisible to us now, would become visible from our rear window. So we might see unexpected objects and colors both in front and in back our spaceship.

Another effect would be on the side window of the spaceship, called relativistic aberration, or the searchlight effect. From the side, you would not only see the colors distorted, but the light would appear brighter towards the direction of motion, and darker away from the direction of motion. This is because, if you are going very fast forward, then you are racing into more photons.

Special relativity also shows that time and length are also different for a moving observer, compared to a stationary one. At 60% the speed of light, time will slow down compared to a stationary observer, but you will not experience anything different. From your frame of reference, time will tick just like it does on earth.

1 meter for a stationary observer would only be 80 centimeters for the moving observer. This is called length contraction. This SHOULD mean that objects would look squished together. This is what’s happening, but NOT what you will see. Instead, you see objects curving away from you, and rotating towards you. The reason is because the photons from the front of the building are reaching your eyes earlier than the photons in the back of the building, so you see it curved. This is an optical illusion. the object in fact contracted.

This same effect means that spherical objects like earth don’t appear squished like a pancake, even though they are contracted, but remain spherical-looking. But they will appear rotated towards you.

This is again an optical illusion, because in reality the object is contracted. What you will experience is that distances are reduced, so a trip to Proxima Centauri, 4.5 light years away, will only be 3.6 light years.

The interesting thing is that even though things would be closer to you, they would actually look farther away when you viewed them from your front window. Likewise looking out the back window things will appear to be a lot closer.

This seems to be a paradox, but as the spaceship moves faster, length contraction in the direction of motion means that objects on the side of the ship move towards the front. In fact, all the light from the side and even behind the ship would shift forward.

Your field of view increases in the direction of movement and decreases behind the spacecraft. Looking forward in the spacecraft would be like looking through a fisheye lens and looking out in the back would be like looking into a zoom lens.

Super-Earths

As we find more and more exoplanets, we glimpse enormous "Super Earths" worlds more massive than our own. Could these harbor life and would we be able to colonize or terraform them?

1. Masses versus density.

2. A quarter more gravity would be within our capacity to live on without overstressing our physical systems.

3. We could kickstart tectonic movement and pop open volcanic activity.

4. Hoop worlds.

5. Presumably higher default gravity would attract more satellites.

Are Cosmic Strings Cracks in the Universe?

Reality has cracks in it. Universe-spanning filaments of ancient Big Bang energy, formed from topological defects in the quantum fields, aka cosmic strings. They have subatomic thickness but prodigious mass and they lash through space at a close to the speed of light. They could be the most bizarre undiscovered entities that actually exist.

General Atomics Hypersonic Blitzer

As dangerous threats to America's safety increase with each passing day, so does the need to combat any potential enemy.

For almost 20 years, a leading defense enterprise has been developing a prototype of a gunpowder-less weapon: the General Atomics electromagnetic railgun.

In a joint effort with the United States Navy, the device features electromagnetic launchers that use electric power instead of chemical propellants. That way, the Blitzer could fire projectiles at speeds never before seen in conventional weapons.

Despite its uncertain future and the potential involvement of the United States Army, these revolutionary railguns might just change the way America fights…

What Happened To The INCREDIBLE Land Train?

This train... doesn't need tracks.

With 56 wheels, this 570 feet long beast would be the longest land vehicle ever built. And it might even have been nuclear-powered.

In the 1950s the US military needed a series of early warning radar systems north of the article circle. Vast equipment and men would need to be transported through unknown hostile terrain - something that even the hardiest trucks would struggle with.

But one brilliant engineer had a solution, a train that could travel overland built from a space-age material - aluminum.

Today we will be looking at perhaps one of the most insane, yet dead ends, in technology - a type of land vehicle that would break records - but never be used.

This is the incredible history of the overland train!

it was called, the LeTourneau TC-497 Overland Train Mark II. It would be able to transport around 150 tons to some of the remote landlocked places in the world. It would have a cabin on board for a six-man crew, with kitchen facilities, and be able to carry an unlimited amount of cars.

And it would be made of the material of the future - aluminum.

But to understand why this train was built, and its mysterious purpose, we need to go back to the beginning...

This story actually begins with a man with a plan - Robert Gilmour LeTourneau.

An adventurous youth, leaving school at 14, saw him studying all sorts of trades including woodcutting, bricklaying, farmhand, miner, and carpenter’s laborer, ending up with a sound engineering background working on car repairs.

But after that dream of being a racecar driver ended, he found himself in debt and needing money,

he went to work as a regrader contractor for the new american highway system.

Seriously this guys early life is totally fascinating and I am not doing it justice.

But it was at this point that he found himself enjoying the mechanical machines used in earthworks, rather than the work itself.

By 1935, he devouted himself to the construction of unquie earthmoving equipment and business boomed.

By the eve of world war 2,

he had multiple factories building custom machines in Illinoi, Georgia, Mississippi, Texas and New South Wales - wait thats next to me here in Sydney!

He was so infulentual that during world war 2, he supplied up to 70% of all the earthwork machinines for the US army -

building a small fortune and also educating him about the sheer order power of the military-industrial complex.

Sensing the winds of change, by 1953, LeTourneau sold his earthworks divisin to the westinghouse company for 30 million usd - which is a staggering 318 million dollars today.

Why you might ask? To devote his future and his company to a revolution - the electric wheel drive.
