  1. Your premise is flawed, impacting asteroids do not slide or bounce like a bullet hitting the ground would, asteroids would not be physically strong enough. You made this claim and touted it as true over and over while never giving a single example of this happening or even if it could happen. I would suggest you bring some evidence to back up your assertion before you try to bring baseless assertions to our attention.
  2. Please give an example of a bouncing asteroid.
  3. Again, please provide a citation for sliding/bouncing asteroids, an asteroid impact releases outrageous amounts of energy. We need to see the justification for sliding/bouncing asteroids.
  4. Can you give us any evidence of a meteorite sliding after striking the Earth? How would that work? What would a meteor have to made of to allow it to survive impact and slide?
  5. Islam is just another religion, a man made mythology that serves only to allow some people to control others. No truth to the proposition that a god exists is any more prevalent in Islam than any other religion. Present a an assertion that Islam is the truth and I will ask for your evidence for this and critique or accept any evidence that can be confirmed. No particular positive or negative premise is given for Islam or any other religion here that I've seen.
  6. No, I wear an outback hat and crocs. Occasionally I wear a pair of denim shorts with the hat and crocs.
  7. I almost lost my job once by demonstrating the leidenfrost effect with molten polymer. I used to work for Dupont and we made polyester. I often ran experiments for various engineers which meant I got to work with various parameters of the process which involved hot polymer 350c. I found that as long as the polymer wasn't degraded I could allow the polymer to pour into my hands and I could mold the thick molten polymer with my hands. The water/sweat on my hands protected me from the hot polymer sticking to my skin. I once showed a member of management this little trick and he lost his mind! He thought I was somehow burning myself to harm the company or something and called to have me escorted off site. The engineer I was working for had to set him down and explain physics to the guy... I kind of felt sorry for him. Hey I drive a Jeep, I prefer off road wanker.
  8. Interesting, I wonder how much hand guns account for the injuries or deaths compared to long guns or shot guns. In gun deaths overall handguns are paramount in cause of deaths. https://www.gafirm.com/legal-blog/commonly-used-weapons-for-homicides/
  9. Good question, I do know of at least one that resulted in the homeowner capturing the invader but most of the time the invader simply chooses a homeowner he suspects is unarmed. From what I understand some reconnoitering happens in most cases.
  10. Home invasions do happen where I live. https://www.wwaytv3.com/news-tags/home-invasion/
  11. I apologize for that, not what I meant to do, in fact I am glad to see you in this thread. Few of us... well I can only really speak for me, and I have no training whatsoever, it's why hunting shotguns are all I own and one of those was bought by me when i was 12, I hitchhiked about 20 miles to get to a feed store ad bought it money I had earned by working for the local famers for the summer. That gun means a lot to me, I understand completely how a gun can be a part of who we are. But at some point we all have to stop making excuses for guns and I am not talking about you. Your expertise and desire to have a safe hobby is up lifting to me. I can honestly say you are the only person i know of who has the foresight to take yours and the safety of others seriously. Around here about all I get when trying to talk safety is how big a hole they can make in a person they decide to kill. All of us need people who can engage this issue without getting "testy" again I am sorry about that, please let that slide and stick with us here.
  12. Let's not mince words, both of us know that the military grade weapons we are discussing is not semi auto handguns, how ever I am willing to include them in the set of guns that no one really needs to own. Handguns are very dangerous and prone to killing bystanders or people in their houses nearby, the danger is exacerbated by the general public thinking that handguns are the safest option and that anyone can handle a handgun. I'm betting you already know this being familiar with hand guns. I am sympathetic to hobbyists like you but the general excuse for owning a gun is home protection. A rifle, hand gun, or AR15 is not required for home defense. A small shotgun, like a 410 with number 5 shot will do the job and make it much less likely you'll kill the neighbors if you miss. The idea that anyone should be able to buy any gun and carry them around is nuts, nothing but postering. Owning a gun is a serious thing at least as serious as owning and operating a car. If nothing else owning a gun should require the same type of training, licensing, and insurance as owning and or driving a car. Hunting is a different issue but can be controlled in a similar way. I personally know people who own various semi auto weapons and shouldn't have access to a slingshot. I also own guns, shot guns, but still guns, and no I don't think no one should own a gun but the ownership of guns has got to be controlled... our children are being killed by this crazy idea of gun ownership being a right.
  13. Are you for or against providing citizens with military grade weapons?
  14. This whole gun thing is crazy, When I go to get gas the local gasoline seller, the gas "service station" died a long time ago, they have around 12 pumps and it's not unusual for there to be 6 or more cars fueling up. I filled up last week and out of 7 people fueling their vehicles 3 had pistols openly on their hips. One had a god damned 50 cal. Desert Eagle! I guess he wanted to make sure he could defend himself from any stray Bradley Fighting Vehicles that might attack while he was pumping gas. I live in a well known liberal university town! This shit is out of control! I think the path forward is clear, far from the general population needing the same guns as the military guns need to be confined... at the very least! Confined to your home and restricted to pump shotguns with #5 shot shells, 410 gauge at most! Personally I think we should be able to open carry knives not guns, but show up in public with a bowie knife on your belt and spend a few days in jail and be fined big bucks but carry a gun and you get special treatment. Yes I think crazy pretty much says it all about gun culture in the US.
  15. Yes, very large meteors manage to land via stripping off speed via burning off much of their material due to "friction" most objects simply burn up before they hit the ground. Spacecraft get by with using the atmosphere to slow down by not plunging uncontrolled into the atmosphere and by taking a path that allows the frictional heat to be bleed off slowly via a shallow angle not by an immediate steep plunge into the atmosphere. Cooling systems? A cooling system that can handle 100s of gs? Yes the heat shielding will have to be quite special I am sure. Yes, I am sure it could be done, but at what cost? Yes very good cooling systems, if there any chance you could elaborate on these special/good systems you keep mentioning? You do realize the gun's breach would still be at ground level and the barrel would still be full of air that the projectile would have to move out of the way, think friction, you would get no benefit from raising the muzzle above the thickest part of the air since this would not change the problem of the package having to fight through the air in the barrel. in fact the rail guns I have seen illustrations of didn't even have barrels, do they have barrels/muzzles? Magic would do the trick as well I am sure. How high would the gun have to be to take advantage of this lower escape velocity? How much difference in escape velocity would you get by launching from an altitude of five miles? So you would just have to lug a rail gun to high altitude and all the fuel it takes to lug the rail gun up to high altitude?
  16. Hmmm, I wonder just how much acceleration a human can tolerate while being supported by water.
  17. Not true, conventional spacecraft start out slow and by the time they reach orbital speed they are in very thin air to no air and little to no friction. Starting out at faster than orbital speed at ground level means you get lit up by friction immediately. Much like a meteor hitting the atmosphere at 25,000 mph, the gs aren't the worst of it. Being heated to beyond the melting point of nearly every material almost instantly would be a big hurdle to get past. Reality what a concept. I was simply stating that this would work much better from an airless body like the moon than the deep gravity well and atmosphere of the Earth. Very true but just how many gs and how fast would a rail gun package have to accelerate to before leaving the gun, the muzzle velocity of this gun would have to be outrageous! Would that acceleration interfere with the electronic and mechanical parts of the package? The rail gun thing is very cool but can you really accelerate a reasonable sized package to orbit, remember you would have to start out quite a bit faster than orbital velocity to get to orbit from the Earth's surface due to friction.
  18. Pemmican? I've seen proposals for doing this and the g forces and the friction would be "difficult" to engineer a solution to these problems from the surface of the Earth. Maybe not impossible but once you compare it to a meteor entering the Earth's atmosphere it makes the problem look insurmountable... of course you could use it to turn mixed vegetables into chunky salsa. I may have overstated this a bit, in my mind i was thinking of the spin launch vehicle, https://www.spinlaunch.com/ not an electromagnetic launch but the g forces would be very similar and the friction equally enormous.
  19. IMHO the main problem of using rail guns to send objects to space would be the enormous friction with the earth's atmosphere. Any object so accelerated would become white hot and evaporate much like a meteor does when it enters the Earth's atmosphere. Then you would have to include engines to allow the object or package to maneuver to the space station. This would be much easier to do if you were launching package from an airless body like the moon.
