  1. But the numbers were unrealistic, and you never used them anyway, except to attempt an invalid force relation. Using real numbers gives some plausibility to the scenario. Using exact numbers is probably not useful. To illustrate: Theia was (supposedly) 10 times the lunar mass, not 1.5 times. The extra mass either escaped (high speed object, mild glancing hit), in which case where did it go? or it hit more directly and was completely absorbed except for the ejecta that managed to coalesce in orbit. Anything not already in orbit has to be moving at a minimum of around 40000 km/hr relative to Earth, so that's a lower bound to any impact from an external object. Mass and speed do not determine force, and force is not directly relevant to the scenario. Force is different everywhere, and is not one value. Fluid dynamics must be invoked. Yes, it was an off-center hit. A straight on shot would have resulted in ejecta with minimum net angular momentum, and thus no moon that requires it. The offset hit would have significantly altered the spin of both bodies, resulting in an Earth will say a 10 hour (or less) day. How long did it take for the moon to get tide locked? Does the simulation answer that sort of thing? Certainly not until any second moon merged into just the one. You don't seem to contribute after this. All your recent posts seem focused on personal attacks against those trying to help. I suppose I will also be the eventual target of that.

  2. What leads people to the particular god they worship is the cultural environment in which they grow up. And that is an empirical fact. Or do you know of any person who grows up in Yemen, spends all their life there, and somehow ends up worshipping Ganesha, or the Christian god?

  3. It's not really known how the Moon got to be such an obnoxious little sister. She just showed up one day with a bunch of circular arguments, orbiting near the point of arrogance, and when called out for it, spent the next several eons acting like the victim. She never really seemed to want anything other than to push against the orbit, which is crazy since this is safe space for her if she'd just mellow out and pay attention instead of trying to make waves here on Earth.

  4. No. You ask questions. You seem to have dropped the attitude. Now drop the nonsense. Many good people here, they could teach you a lot. Take my advice. Bye.

  6. In everyday use, the word "theory" often means an untested hunch, or a guess without supporting evidence. But for scientists, a theory has nearly the opposite meaning. A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts. Theories are concise, coherent, and predictive, and they can apply to a wide range of phenomena. They can also integrate and generalize many hypotheses. To be accepted by the scientific community, a theory must be supported by many different lines of evidence. This doesn’t just miss the mark, it’s not even wrong.

  7. A typical home WiFi router makes use of something called DHCP (dynamic host configuration protocol) to assign LAN (local area network) addresses to all the different devices logged into your home network. These LAN addresses usually take the form of IP quads formatted as 192.168.x.x where the 192.168. prefix is a special index which is only valid as an address on a local network - i.e one that can’t be reached directly from the WAN (wide area network) or the public facing side of the internet. The router’s DHCP protocol assigns these local LAN addresses to your devices on ‘leases’ which are time limited and can expire. This can be one source of confusion - if a lease expires, and/or a new device is added to your local network, and the DHCP process bounces these 192.168.x.x values around, it will unexpectedly assign a new address to a particular device. Your home router has an internal address table of all currently connected devices on your LAN that you can inspect. Home routers also make use of something called NAT (network address translation) which usually works in conjunction with its protective firewall and TCP Port numbers. The latter are used to ensure that incoming data packets from the internet reach the correct device on the local network. You can set up NAT ‘Port Forwarding’ rules in your router to ensure that particular services/message types are routed to one specific device on your local network. The public facing WAN address of your broadband home router is assigned by your ISP (internet service provider) and should in theory be static - i.e unchanging. When I first got home broadband, I was given a static public IPv4 address which didn’t change for the next 17 years. Unfortunately that ISP went out of business last year, and we switched to a new provider whose ‘Static’ public IP addresses turned out to be anything but static - they seem to change every time the router is rebooted, or receives a software/firmware update. My new router has now changed its public IP seven times since being installed last December. The amount of time you are likely to spend fiddling with such networking details depends on quite what you normally do with your home computers. I’m a long-time IRC user and Eggdrop channel protection bot admin - and those ancient things are hell on wheels to configure correctly behind a home router if network IP values start changing under your feet. You wind up getting a crash course in TCP networking theory !

  8. Well I believe everyone agrees we need tighter constraints on the impact possibilities nothing is particularly conclusive at our stage of research.

  9. IP address can be public or private. IP address can be static or dynamic. So we have four combinations: public static, public dynamic, private static, private dynamic. IP address can be in version v4, or in version v6. IPv4 is four decimal numbers separated by dots. IPv6 is many hexadecimal numbers separated by a colon. Be careful with these. They can encode a MAC address of a real machine, which can uniquely identify a person worldwide. A home computer with a WiFi card or a smartphone/tablet connected to home WiFi router with plugged modem, most likely has a private dynamic IP address assigned by DHCP. This will most likely be 192.168.0.x, where x is from 2 to 254 (because 0 and 255 are special purpose, and 1 is usually router). or 192.168.y.x (y=0...255). If you use Android smartphone as hotspot, your IP will be something like 192.168.43.100 or so. https://en.wikipedia.org/wiki/Dynamic_Host_Configuration_Protocol If you connect the modem directly to your computer and your ISP is cool, you may have a public static IP address or at least a public dynamic IP address. Doubtful. Nowadays ISPs are screwing people over and such options are only for enterprises for more $$$.. You can check your IP addresses (yes, addresses! You can and will have multiple IP addresses!) by Start > cmd.exe and then ipconfig /all (on Windows), or ifconfig (on Linux). A typical computer (whether or not desktop or laptop) has at least 6 private IP addresses. 127.0.0.1 (IPv4 localhost) ::1 (IPv6 localhost), 192.168.x.y (IPv4 ethernet card) some IPv6 for ethernet card, 192.168.x.y (IPv4 wifi card) and some IPv6 WiFi card. If you will plug more modems or external WiFi USB, you will have more.. What showmyip.com etc. shows is IP address of your router/modem, or even your ISP IP address. Multiple people can have it. Once you have it, paste it here https://ipinfo.io/ to learn what is ASN. IP address with a slash like /16 means 16 bits are zeroes in the mask i.e. mask is 255.255.0.0. /8 means mask is 255.0.0.0 etc. If you have public static IP address, you can go to router configuration (typically in a web-browser open http://192.168.0.1 (no SSL!!! manually edit if needed) ) and configure port forwarding to your real machine. Install XAMPP on your desktop/laptop, configure port 80/443 forwarding to your private static IP (disable DHCP/configure DHCP to make your IP private static), and ask a friend (or use smartphone with LTE/5G) to visit your web server. https://www.apachefriends.org/pl/index.html (This way you can share things with other people/friends/family, with a higher level of security than sending them via email or to the cloud.. which is one of the most stupid things people can do. Sextels of Hollywood actresses came from the cloud. Their cloud) They want your money to make it static (so you'll have less trouble installing some server at home). Hundred or thousands of people share the same IPv4 address at the same time.. There is only 2^32 = 4.3 bln IPv4 addresses. Some not assigned, reserved, special purpose.. People have a couple smartphones, a couple computers, a couple of tablets, a couple of laptops etc. Every IoT device (e.g. camera, payment terminal) can have a separate SIM card.. Owners want/need to have their IPv6 address to connect them. IPv4 was exhausted in 2011. https://en.wikipedia.org/wiki/IPv4_address_exhaustion Run this command in a loop in a script: wget -q -O- http://ipecho.net/plain With some delay, such as 15, 30, 60 minutes after each check. If they are really using a home WiFi router (and then, f.e. fiber cable), they should have the same IP address (as reported by showmyip.com, etc.) as all other devices using the same Internet connection (as long as you check things within a couple minutes, not hours or days). You need to check this. Once you see the IP, check each one individually in ipinfo.io ) The MAC address (BTW, it has nothing to do with Macintosh) is on the Ethernet card or WiFi card. Each of them is different. So you can have many different MAC addresses.. as many as network interfaces.. The arp command is used to display the MAC addresses of other machines on the LAN. Your machine is not included. On the Linux you do first e.g. nmap 192.168.0.0/24 and then arp. Otherwise some devices may be missing (and they will be if they have disabled ICMP)

  11. A theory is a proscribed possibility but that doesn't mean it's true and never will. If we have 10 theories on a subject and one turns out to be correct then the other 9 may as well be on toilet paper.

  12. The theory of everything must contain all matter and energy The universe is connected by force and it is contained in all things. Any theory can be proven wrong at any time when an undeniable fact moves in and destroys it.

  14. As I stated before all things are vibrating particles, so all things are one and the same at the smallest level. We are in the universe and all things are a part of us as we are a part of them. It is like water in a bucket each part of the water is the water, We are a part of the universe so we are the universe, and the universe is us and all things. The universe contains itself as one unit.

  15. The atoms that make up a thought are the same as all the atoms in the universe, We are the thinking atoms that reside in and among all matter. It is the mind that segregates giving things names and numbers but the universe does not work like that just a group of atoms in our heads that likes to think in this way. I wasn't talking to you, was I?

  16. See, you fail to ask me a single question. Is it what I asked you or something else, please, and thank you. The theory of everything is related to all of the matter and energy in the universe. We have no way of knowing how the universe began and we have no way of knowing where the universe ends. We do know that the universe consists of matter and energy, and we don't know if anything else exists outside of matter and energy. This leaves only one possibility, the reality we live with and in, and that is matter and energy and it is only that we have to work with. The most prominent feature of the universe is energy in all of its forms, energy takes on matter and matter can return to energy under extreme situations. It is said that matter came into existence from energy, and it is predicted it will all return to energy again if the universe collapses. So without knowing the course or the end the theory of everything is a rebirth of all energy, or cold lost matter. We live in this reality and to think we can know more is rather hopeful. We know what we know and we don't know what we don't know.

  17. The Theory of Everything in my mind is the formation of all matter and all energy whenever that took place.

  18. I have had discussions with others but you just dirty the water. If you don't like what I say then go away and leave me to communicate with others. I know you would get much joy from having me kicked off the forum but I can't do anything about that. I have reframed from being angry and retaliating so you are trying to find other ways to get rid of me. I can see through you and others can as well.
