Let's assume atmosphere effects cause parallax based distance measurement to fail by the huge amount you claim. Then please explain how parallax measurements are consistent with many other kinds measurements? All the various measurement methods fail but still produce similar outcome, how? Please provide a detailed explanation. Not unsupported claims; claiming that atmosphere can cause an effect is not the same as there is an effect.

Let's assume for a second you are correct. Then measurements that rely on angle and known distances on the surface of the earth gives wrong scale or distance for nearby celestial bodies. According to your idea: is basic trigonometry wrong or is measurements of distances on earth wrong? (Or both, or something else?) Please provide a detailed explanation.

I do not understand where you addressed this: The distance to Venus is more than one light minute. Distance to celestial bodies can be measured with experiments based on parallax and such a measurement relies on rather basic trigonometry. If your claim is right then every measurement of for instance distance from earth to Venus and earth to sun are wrong? Please provide a detailed explanation why you reject the results of basic geometry. Please include necessary mathematics to explain your version of parallax measurements. Does that matter? When someone shows enough interest in your thread to actually read it, compare the facts with established theories, try to draw conclusions and then ask for followup information it could be in your interest to try to answer and clarify rather than complain, repeat or add unrelated information?

That means you have a stable connection at this time. Options: Leave the terminals running until there is an issue and check the output. Or start both terminal commands again as soon as there is an issue with internet. And/or make a wild guess that DNS is the issue and add 8.8.8.8 as secondary DNS in your router though the administrative interface you posted. Side note: As a reference: example output when there are issues with the connection: % ping www.apple.com | grep -v "bytes from" PING e6858.dsce9.akamaiedge.net (2.22.41.97): 56 data bytes Request timeout for icmp_seq 154 ping: sendto: No route to host Request timeout for icmp_seq 155 ping: sendto: No route to host If internet connection is completely down there is approximately one new error every other second or so. For intermittent errors there will be a few lines printed, then nothing for a period of time. (Not possible to tell for how long) If the connection is very reliable then there will be no timeout or "No route" messages for maybe days or more. Due to the time difference I may not be able to followup until tomorrow.

I think you missed part of the command, "bytes from". Copy paste the string below ping www.apple.com | grep -v "bytes from"

That is ok, it just goes on. To stop the command you can use CTRL-c to get back to the prompt to type other commands. Next we will try to see if there is an issue externally. This may take some time to spot depending on how often there is an issue. We will modify the command to help Open two terminal windows In the first terminal type ping 192.168.100.1 | grep -v "bytes from" The ping will try to connect to the router. the vertical pipe sends the output to another command called grep. The grep will filter out all "OK" answers so that only errors will be printed on screen. That means you can leave the command running and check after a while that there are no timeouts or other errors. in the second terminal type ping www.apple.com | grep -v "bytes from" (Or any other reasonably stable website of your choice) You now have two ping running. If the issue is on your LAN or in the cable or adapter you should get errors in both terminals at the same time If your errors are in router or outside then the second terminal will likely print many more errors than the first terminal

No problem with the interpretation, we can solve that as a joint effort. I interpret that as you have a router that has address 192.168.100.1 as seen from your linux box. In the terminal we first assure that there is a connection from your Linux box through the cable to the router. Type the following command and check the output: ping 192.168.100.1 The outout should be something like: 64 bytes from 192.168.100.1: icmp_seq=235 ttl=53 time=38.640 ms 64 bytes from 192.168.100.1: icmp_seq=236 ttl=53 time=47.708 ms 64 bytes from 192.168.100.1: icmp_seq=237 ttl=53 time=38.423 ms 64 bytes from 192.168.100.1: icmp_seq=238 ttl=53 time=43.113 ms It is NOT ok if there are many Request timeout for icmp_seq 103 or ping: sendto: No route to host I have not seen such an issue but I have limited experience. I have used two different USB to ethernet adapters on same LAN without issues but not the same brand.

Unless I have missed something we have not yet determined if the error is inside your router, in the router or in a service provided by your ISP. Facts we have, hope I got this right. Italic are my conclusions, guesses and reasoning*: More that one equipment connected you the router gets the issue. Sometimes simultaneously and sometimes not. The problem is hence not likely a single cable or adapter or equipment on the LAN. It's in the router or external at the ISP. TV tuner seems to be the most stable one. The tuner is more likely to keep e few connections open for a longer time. Computers in use are more likely to connect/reconnect when user switches network. What version of linux are you running? I may be able to provide an easy step by step guide how to use terminal and ping. (Maybe I need help from @Sensei on this one depending on version)

Happy new year. May I suggest that you address the questions regarding your ideas before adding more pictures?

Here is what looks like the same passage from English wikipedia. https://en.wikipedia.org/wiki/Michelson–Morley_experiment Note that the above is a full section showing more context and interpretation. Looks like the results of that experiment showed a different outcome that you try to argue?

ESA has an introduction about CubeSats. This information seems not very biased towards a specific manufacturer: Source: https://www.esa.int/Enabling_Support/Preparing_for_the_Future/Discovery_and_Preparation/CubeSats The form factor of a CubeSat allows them to be stacked and placed in unused space in a launch vehicle.

I'm sure your posts makes sense to you, to me it looks more like pareidolia. Or the result of using image editing software. This discussion seems to move into areas that I'm not interested in so I'll leave until there is some science to discuss.

In case you find an issue with the DNS and need to add a secondary / temporary one: try to Google "how to set google dns in router modem XYZ" (replace router modem XYZ with your brand and model) One more: You can also check your ISP's web page or support forum if there are known issues on their side (or twitter or whatever channel they use to communicate issues)

Good catch! I can't disable my DNS at this time, did a quick check with Curl to verify your comment: (... means I removed logs not necessary for this discussion) curl -v https://8.8.8.8 * Trying 8.8.8.8... * TCP_NODELAY set * Connected to 8.8.8.8 (8.8.8.8) port 443 (#0) ... subjectAltName: host "8.8.8.8" matched cert's IP address! * issuer: C=US; O=Google Trust Services; CN=GTS CA 1O1 * SSL certificate verify ok. ... <HTML><HEAD><meta http-equiv="content-type" content="text/html;charset=utf-8"> <TITLE>301 Moved</TITLE></HEAD><BODY> <H1>301 Moved</H1> The document has moved <A HREF="https://dns.google/">here</A>. </BODY></HTML> * Connection #0 to host 8.8.8.8 left intact * Closing connection 0

Good; means we can rule out issues between that equipment and the router. Ok! Do you know how to open a terminal window and type commands? If so, type in: ping 8.8.8.8 If there are intermittent errors an external address such as googles DNS (8.8.8.8) would look like this: >ping 8.8.8.8 PING 8.8.8.8 (8.8.8.8): 56 data bytes 64 bytes from 8.8.8.8: icmp_seq=10 ttl=118 time=13.940 ms 64 bytes from 8.8.8.8: icmp_seq=11 ttl=118 time=13.774 ms 64 bytes from 8.8.8.8: icmp_seq=12 ttl=118 time=23.898 ms ping: sendto: No route to host Request timeout for icmp_seq 13 ping: sendto: No route to host Request timeout for icmp_seq 14 Request timeout for icmp_seq 15 64 bytes from 8.8.8.8: icmp_seq=16 ttl=118 time=125.050 ms 64 bytes from 8.8.8.8: icmp_seq=17 ttl=118 time=4.924 ms Note the timeouts above, they hint that there is a connection issue at that time. In this case I intentionally disconnected from the network to get this error. If you ping your router instead of (ping 192.168.100.1 instead of ping 8.8.8.8 since I guess 192.168.100.1 is the address of your router) there would be no timeouts unless there is an internal issue in your network.

Ok. I recommend taking a look at Sensei's post. Ask further questions if you get stuck. One thing: When one computer has the DNS problem, can you still surf to the web page https://8.8.8.8 ? (Google's DNS server via IP address instead of the DNS name) Since you seem to have the issue also on the tuner I would look at issues with the router first.

@Externet I have quickly read through Sensei's answer and he has posted the full description of what I had in mind but I intended to move step by step. You may skip by questions look at Sensei's steps first. Note: My router had the option for a manual DNS-server entry in addition to the DNS server ISP provided via DHCP; adding google's DNS 8.8.8.8 as the secondary DNS server helped in a case where the ISP had issues.

As far as I know, according to accepted models: On large scales every location will be a center of expansion. All observers will observe distant objects mode away from them. Happening, as in happening right now? Please show the details how your idea could fit into (or if necessary modify) accepted models. Also note that we already have Special and General Relativity theories; time is not absolute.

Not sure this will help but let's try. Questions: -All internet connected equipment at your home gets the problem, all gets the problem at the same time? -How is the router (modem) connected to internet? -What happens if you power-cycle the gateway when problem occurs, does that fix the issue? (I have had similar looking problems (Linux, Apple and other equipment) and in my case it was the router + DNS service at the ISP that was the issue. Not yet sure if this applies to your case)

Ok. So how does the communication with for instance a mars rover work according to your idea? The distance is approximately 3-21 light minutes depending. (I'll postpone commenting on other issues such as Aether, photon life time and others)

That does not seem to match observations*. Can you explain how a signal traveling at the speed of light, for instance to mars, takes more than one minute to get there? Or, in the case of Voyager: Source: https://www.nasa.gov/press-release/nasa-s-voyager-2-probe-enters-interstellar-space *) There are other issues as well, I choose to comment on this specific issue in this post.

Hello! Please explain the rules in more detail. What moves are allowed. How does a player win the game? What happens if there is a draw in a smaller board? Etc.

You repeat the same things again. Using capital letters does not help making your ideas practical. Just an example: An image classifier in python* has 168 unique words**. That means there are approximately [math]2.5*10^{302}[/math] ways to reorder the words in that piece of source code. Do you know how large that number is? When you analyze that number and the computational complexity off your approach, what does that tell you? *) I picked this one: https://github.com/keras-team/keras-io/blob/master/examples/vision/image_classification_from_scratch.py **) not counting comments ***) https://www.wolframalpha.com/input/?i=permutations+168+of+168
