Get a 10mm glock and put it in a roni carbine kit lol that would be a blaster use them copper wadcutters for bear stopping lol i think lehigh make them they have near. 44 mag power well from a 2 inch barrel the. 44 from say a marlin or something is beastmode under 300m its got similar if nit more power than some full rifle rounds i think a 45.70 marlin with a little red dot on it would still be a good fighting rifle ud be able to literally blow walls ect apart or whatever barriers ur opponents are behind just use extreme penatrators or anything brass or copper amd have a 4 round short shotgun with buck shot and a. 22 magnum revolver 4inch barrel and a 10 round cylinder they aint cheap and normally made in Germany i prefere rifles anyway a 6.5 creedmore bolt action and a high capacity carbine in 223 would do u just need range and thats easy if your alert

If Mercury is the core of a gas giant, as recently speculated, due to its density, it wouldn’t have enough metal in it, to build a Dyson sphere. Even assuming an alloy strong enough, to do the job, could be created from common matter, that is. There is also a problem with the center of gravity of the sphere, which would be where the sun would be and would be EXTREMELY unstable. Yes, I’ve done the math. It’s not as hard as you’d think.

“Two possibilities exist: either the coffee has been sipped or this coffee has been sipped. Both are equally terrifying.”

@Shawnaldo75 Even then, they are not really alone. Unless you are talking about after everyone is dead. Then whatever was doing the killing is alone.

@Shawnaldo75 I get your point. I guess on the universal scale, it could be different. If we really are truly alone, then why are we here in the first place? Of all that vast distance and matter, it is just us. That is terrifying. Statistically speaking, it is way more likely that we are not alone. What then is out there? That is also terrifying.

What about we were alone, and then dog?

YES

The launcher is commonly called a mass driver.

I came to the comments to say exactly this.

Cool. Will definitely look into this then!

Railguns shooting satellites, or satellite shooting railguns?

I'm not sure this idea tracks linearly with the increasing complexity of technology. There are definite limits to how much technology can progress, to the nature of what can possibly be built, the laws of physics. Laws we can prove which mean it is only possible for anything ever to go so far, so fast etc etc. In your example, the tribal people could only imagine a giant drum because they had no current understanding of where these provable limits lie. You could explain to them in the space of a few hours that the sound their drums make are signals that are received by the ears of the neighbouring islanders and that a mobile phone is no different to a drum it just produces a signal that human ears cannot receive but that another piece of technology can receive. The basic concepts of drum sound waves impacting human ears vs a way more powerful electromagnetic wave impacting upon a technological ear aren't really worlds apart. But to do what a Dyson sphere could do but be way easier/smaller to build would require us to disprove laws of physics which is a way taller order than just explaining how a new piece of technology does the same thing the human body does but better, but still definitely within the hard limits of what can possibly be achieved

What a lot of people don't realize is that we can build a Dyson Swarm with current technologies. All it really takes is the labor. What would make it the easiest in the near term is the construction of efficient Von Neumann probes to disassemble Mercury (probably) to turn into more robots, solar power satellites, solar shades, StelLASERS, etc. All we really require is the will.

yea, the sun is just a big nuclear fusion reactor. maybe we could just, ya know, scale it down a bit.

Well if having a beard and being bald is your criteria,ok.

Yea, also if advanced intelligent life were really that common then they almost certainly would've colonized the entire galaxy (including our own planet perhaps billions of years before complex life evolved thus precluding our existence), or at a bare minimum left behind enough wreckage for us to have a fairly easy time seeing signs of alien life. As a quick demonstration, Tabby's star is approximately 1500 light years from us, Milky Way is about 52000 light years in radius, assume that in a disc of the milky way of about 1500 light-years in radius you have about 1 advanced civilization arising every 100,000 years, and you get 1200 new civilizations every 100,000 years, assume that life first could've arisen 5 billion years after the Milky Way was formed, about 8 billion years ago, and you get approximately 60 million civilizations that have had the ability to take control of their solar systems and start venturing out to colonize other stars. Assuming the higher end of number of stars in the Milky way of about 400 billion, that means there'd have been about ~6700 stars per civilization they could colonize. Certainly a lot, but given that the average age of these civilizations is ~4 billion years old, they would only need to colonize about 2 stars every million years in order for the entire Milky Way to have been claimed by someone, leaving various traces of their existence everywhere, and probably again precluding our existence as we would've been either disassembled, or colonized and terraformed, long before we could arise. As a note on that perspective, if the galaxy is empty of intelligent life, and we decide to go gungho on colonization, humanity can colonize the entire Milky Way in a measly 100,000 years. Even if most civilizations never cared about going beyond their home planet even if they had the technology to (and seeing Tabby's star be engulfed in a Dyson Sphere would indicate that those 1200 new civilizations every 100,000 years would probably usually build dyson spheres even if they never bothered to colonize other star systems, which by itself would be fairly unlikely to have escaped our notice even if they were only a small fraction of all the stars in the sky), it only takes a couple particularly gungho civilizations that are smart enough to leave the ancient giants well enough alone until they can defend themselves from them, and take most of the unclaimed stars for themselves to get a civilization spanning the galaxy, again precluding our existence. So if advanced intelligent life is indeed that common, then our understanding of physics would have to be fundamentally wrong on a major level, that made dyson spheres and colonizing other star systems relatively pointless and expensive compared to whatever new options become available with the new physics, in which case it would beg the question why any hypothetical aliens around Tabby's Star would be building one if there wasn't any point to it, and why the galaxy isn't awash in these dyson spheres if apparently so many civilization push through with building one that we could see one being built a mere 1500 light years away, only within decades of us both getting the technology to search for them, and coming up with the concept so we know what to look for.

Check out Issac Arthur's channel, he goes beyond red dwarf stars to black hole farming

@@Treviisolion You are making way too many unsubstantiated assumptions and way too many mistakes in your calculations, as well as leaving out ton of possible limiting factors.

Kibernautas i double checked my calculations, they should be correct though I did accidentally say diameter instead of radius in one part so I did fix that, and that would change the numbers as well. And your right, I am making assumptions that are unsubstantiated, but perhaps more than you might think, because we kind of have to until we get more evidence. 1. That the laws of physics we know are mostly correct. If they aren’t then what we think most likely that aliens would do might not be true. 2. That any civilization advanced enough and desirous enough to leave their home planet and build a dyson sphere would also be both advanced enough to colonize other stars (which they definitely are especially as a dyson sphere can also help accelerate ships to lightspeed to travel to other stars) and probably expansionist and greedy enough to want to colonize other stars. Perhaps not all, but at least some fraction of them considering that is probably the path humans would take. 3. That the earliest a civilization could have arisen was 8 billion years ago given the Milky Way galaxy’s age of 13 billion years and the Sun’s age of not quite 5 billion years. That said realistically advanced civilizations would probably be more common the older the galaxy gets, but I made a simplification for the math, as it doesn’t change the answer much, and also makes it more likely for some ancient civilization to just been first on the scene and if desirous colonized the entire galaxy stripping it for parts and whatnot to feed either a unified galactic civilization (if this species were particularly long-lived and cooperative or somehow able to get around the lightspeed barrier for at least communications as otherwise the outer regions of the galaxy would need to wait tens of thousands of years for communication which at least for current humans would be impossible to maintain a cohesive culture and government) or a field of galactic civilizations most of which would be unable to really interact with each other thanks to lightspeed limitations. 4. This is the assumption most obvious that I made, and the one with perhaps the least backing. The one that on average in a radius of 1500 lightyears you get 1 advanced civilization every 100,000 years. There are a couple of reasons why I chose this, and I did make some simplifications such as ignoring the density of stars in a given radius of the milky way both as a factor in how many chances they provide for advanced civilizations to develop and how the density itself could affect the chances of advanced civilizations developing and assumed that the chance is approximately equal across the galaxy. Mainly because it doesn’t matter for the point I’m trying to make. Putting that to the side for the moment and returning to the main assumption, I chose 100,000 years both because it is approximately the amount of time at a minimum a civilization would need to colonize the galaxy if located near the fringe of the Milky Way as opposed to the center (where the number would be more like 50,000 years), and because if true means that we would be incredibly lucky to be seeing a type II civilization that hadn’t gotten around to colonizing the stars around us (or us if they didn’t really care for respecting life on other planets), and was probably only starting considering that we don’t see a large region of space that gravitationally appeared to have stars, but was dark due to their stars being covered in Dyson Sphere, depending on the build we may also see points of infrared light (or other light depending upon temperature of the dyson sphere) being given off as waste heat but almost nothing in the other bands, certainly nothing that would look like any known type of star. You can either decrease the number 100,000 which would make it less odd that we were observing such an apparently new civilization so close to us, but also drastically increase the number of civilizations that should have existed before now, or increase that average year time and decrease the number of civilizations that should have existed and thus make it more reasonable why the galaxy is apparently empty of any signs of life while also making it more unlikely we can see such a civilization so close to us. The 1500 light years radius was based mainly on distance from us to Tabby’s Star and the fact that it appears that if there is a Dyson Sphere being built there that no other Dyson Spheres have been built anywhere else nearby, at least not in large quantities enough to create a noticeable dark spot in the sky that appears to affect things gravitationally (unlike dark matter which appears to be diffuse and relatively evenly spread out though clumping up near the center of the galaxy). There is also the implicit assumption that we have passed enough great filters that reaching a Dyson Sphere one day is decently likely so we can count ourselves as a nascent advanced civilization. You can remove that assumption in which case the radius of on average 1 advanced civilizations arriving in a given time-period is unknown, though you’d have to imagine they are still common as otherwise it’d be unlikely we’d be the ones to see a nascent type II civilization out of all the pre-type I civilizations that would no doubt exist in such a case. And again it only takes one civilization colonizing most of the galaxy to leave behind large traces that would be much easier to discover than anything we’ve found. A hundred stay-at-home civilizations I can see. A thousand existing and not one militant xenophobic one that colonized the galaxy in order to prevent any new civilizations from arising or even just a diplomatic yet explorative one that colonized only a certain type of star across the galaxy but still leaving behind major traces of their activities, let alone among ten thousand, hundred thousand, a million different civilizations capable of reaching Type II, not one having the aspirations to try for Type III? I find myself doubtful of such a prospect, but we only have one data point, so we can’t be certain. If you know of any other assumptions I made then let me know.

@@Treviisolion Lets address your calculations. They are not mathematically incorrect, they are factually incorrect. Milky Way is 13 BYO, and on Earth it took roughly 5 BY for civilisation to arise. You simply subtracted 5 from 13 and came to conclusion that first civilisations would start to appear 8 BY ago. No problem with math, problem with reality. 13 BY ago there were almost no other elements except for hydrogen, helium and bit of lithium. Billions of years are needed for stars to create other elements, explode as supernovas, spreading those elements. It takes billions of years more of such stars exploding for other elements to accumulate in amounts substantial to form new solar systems that have Earth like planets. When there were enough heavier elements to form Earth like planets? Something between 5 and 13 billion years ago, though I would say it should be closer to 5 BY ago, as higher concentration of heavier elements would lead of mostly "Super Earths" forming, which is not good for civilisations. If we put time of forming solar systems with Earth like planets, lets say 8 BY ago, subtract 5 BY for civilisation to arise, you get first civilisations arising 3 BY ago, not 8 BY ago. There lies my problem with your calculations.
