O 5G Mrežama: Fizika za glupane 1 na 1 // About 5G Networks: Physics for Dummies 1 on 1

Tema: 5G i hipoteza zavjere.


Exkurs: Zašto uporno koristim izraz “hipoteza” umjesto “teorija”? Jednostavno iz sljedećeg razloga: da bi jedna tvrdnja dobila status teorije, ona prvo mora biti indirektno (npr. arheoloski) ili direktno (npr. posmatranje i mjerenje fenomena, eksperiment) naučno potvrđena i da iz uzročno-posljedičnih veza unutar takve tvrdnje, te uz njenu povezanost sa prirodnim zakonima/procesima UVIJEK dobijamo očekivane rezultate. Npr. evolucijska biologija. Sve dok jedna tvrdnja nije faktualno POTVRĐENA, ona nije teorija, nego obična (često prazna) tvrdnja, u širem smislu hipoteza.

KAKVE SVE KATASTROFE U SVETU IZAZIVA 5G MREŽA?!

Sve moguće bežične mreže (zajedno sa 5G), svetlost, Rentgen i radioaktivno zračenje su elektromagnetni talasi i opisuju se na isti način. Jedine razlike između 5G i bilo kog navedenog zračenja su:
– FREKVENCA/TALASNA DUŽINA, u slučaju 5G uglavnom između 0.6 GHz i 2.6GHz (koji se još od 2009. javljaju kod 4G), ali biće i ~30GHz (https://en.wikipedia.org/wiki/5G_NR_frequency_bands)(https://en.wikipedia.org/wiki/List_of_5G_NR_networks)
– EMITOVANA SNAGA

Evo koje se sve radio frekvence koriste u Americi, a vrlo je slično i kod nas (https://tinyurl.com/ybdk297y)

5G je u istom opsegu frekvenca sa kojima živite čitav svoj život, osim što 5G predajnici emituju mnogo nižu snagu. Da li ste se ikad zabrinuli što se TV signal emituje na 0.698 GHz i 10 000 [W] vati? Zašto biste onda brinuli o 5G na 0.700 GHz i 1 W. Je l’ vas brine radar za avione i brodove koji emituje na 0.960 GHz? Oni rade na ozbiljno većim snagama od telefona… Dobar deo opsega frekvenci na kojima 5G radi je oko vas ceo vaš život i nikad vas nije povredio. Isto važi i za frekvence >30 GHz. Poređenja radi, Sunčevo zračenje (svetlost) je takođe elektromagnetni talas kao i 5G. Frekvence je između 230 000 GHz i 1 000 000 GHz i intenzitet Sunca na površini zemlje je oko 1000 [W/m^2] vati po metru kvadratnom.

U objavama viđam da neki brinu da radio talasi mogu da izazovu rak (da oštete DNK). Apsolutno nijedan elektromagnetni talas niže frekvence od UV zračenja (na slici levo) nema dovoljnu energiju da izmeni ljudski DNK. Radio talasi su daleeeeko na sigurnoj strani u poređenju sa rentgenskim zracima i radioaktivnim gama zračenjem. Oni su bezazleniji od vidljive svetlosti, od Sunčeve svetlosti. 5G elektromagnetni talasi fundamentalno nemaju dovoljno energije da izbace elektrone iz atoma, da jonizuju atom, što je mehanizam po kojem se DNK nasilno menja/oštećuje.

Ukoliko vas dodatno brine blizina izvora 5G, znajte da intenzitet opada sa rastojanjem na kvadrat. Ako je npr. na 1m intenzitet talasa 1 W/m^2, onda će na 10m intenzitet biti 0.01 W/m^2. 5G predajnici kao prvo imaju malu izlaznu snagu, a kao drugo indukcioni efekti se dešavaju na jako malom rastojanju i izolovani su dobro.

ZAKLJUČAK:

– 5G nema nikakve uzročno-posledične veze sa bilo kojom katastrofom u svetu.
– Dokazano ne može da izazove zdravstvene probleme na način na koji UV zraci i radioaktivno zračenje mogu i nema nikakvih čvrstih dokaza da time što ga koža apsorbuje (kao što apsorbuje sunčeve zrake) dugoročno pravi zdravstvene probleme.

Uporedite brojeve i prosudite sami. Valjda ste sada manje zabrinuti oko 5G predajnika. Još uvek velika većina ljudi nema mobilne telefone koji podržavaju visoke frekvence, pa se i ne koriste.

Ovo se raširilo više nego što sam mislio. Inicijalno je trebalo da na srpskom pruži par uprošćenih objašnjenja mojim prijateljima koji nisu informisani o temi, a onda je postavljeno na “Public”…
Većini onih za koje sam ovo pisao ne znače mnogo informacije, tekstovi i objašnjenja na engleskom, ali pošto je pažnja porasla – evo diskusije u kojoj sam učestvovao pre objavljivanja posta.
Skrećem pažnju na komentar korisnika Imaccaro koji je dao lepe primere koje sam proverio, iskoristio i iza kojih stojim u ovom postu:[https://www.reddit.com/…/recently_the_5g_causes…/]
Svi navedeni pojmovi su poznati još od pre druge polovine 20. veka, a neki od 19. veka. Objava je sažetak nekoliko lekcija iz fizike.

Topic: 5G and the conspiracy hypothesis


Excursion: Why do I keep using the term “hypothesis” instead of “theory”? Simply for the following reason: in order for a statement to be given the status of a theory, it must first be indirectly (e.g. archaeological) or directly (e.g. observation and measurement of phenomena, experiment) scientifically confirmed and that from the cause-and-effect relationships within such a statement, and in connection to natural laws/processes, we ALWAYS get the expected results. For example evolutionary biology. As long as a statement is not factually CONFIRMED, it is not a theory, but a simple (often empty) statement, in the broader sense of a hypothesis.

WHAT KIND OF DISASTERS IN THE WORLD CAUSES THE 5G NETWORK?!

All possible wireless networks (including 5G), light, X-rays and radioactive radiation are electromagnetic waves and are described in the same way. The only differences between 5G or any radiation are:
– FREQUENCY/WAVELENGTH, in the case of 5G mostly between 0.6 GHz and 2.6GHz (which have been occurring since 2009 with 4G), but there will also be ~30GHz (https://en.wikipedia.org/wiki/5G_NR_frequency_bands)(https://en.wikipedia.org/wiki/List_of_5G_NR_networks)
– EMITTED POWER

Here are all the radio frequencies used in America, and it is very similar in Serbia (https://tinyurl.com/ybdk297y)

5G is in the same frequency range you’ve been living with all your life, except that 5G transmitters emit much lower power. Have you ever worried that a TV signal is broadcast at 0.698 GHz at 10,000 [W] watts? So why should you care about 5G at 0.700 GHz and 1 W. Are you worried about radar for aircraft and ships broadcasting at 0.960 GHz? They operate at seriously higher powers than phones… A good portion of the frequency range that 5G operates on has been around you all your life and has never hurt you. The same applies to frequencies >30 GHz. By comparison, solar radiation (light) is also an electromagnetic wave as is 5G. The frequency is between 230 000 GHz and 1 000 000 GHz and the intensity of the Sun on the surface of the earth is about 1000 [W/m^2] watts per square meter.

I see in the posts that some worry that radio waves can cause cancer (damage DNA). Absolutely no electromagnetic waves lower in frequency than UV radiation (pictured left) have enough energy to alter human DNA. Radio waves are far on the safe side compared to X-rays and radioactive gamma radiation. They are more harmless than visible light, than sunlight. 5G electromagnetic waves fundamentally do not have enough energy to eject electrons from an atom, to ionize an atom, which is the mechanism by which DNA is violently altered/damaged.

If you are additionally concerned about the proximity of the 5G source, know that the intensity decreases with the square of the distance. If, for example, at 1m the wave intensity is 1 W/m^2, then at 10m the intensity will be 0.01 W/m^2. 5G transmitters, firstly, have a low output power, and secondly, induction effects occur at a very small distance and are well isolated.

CONCLUSION:

– 5G has no causal relationship with any disaster in the world.
– It has been proven that it cannot cause health problems in the way that UV rays and radioactive radiation can, and there is no solid evidence that it causes long-term health problems when the skin absorbs it (like it absorbs the sun’s rays).

Compare the numbers and judge for yourself. I guess you are less worried about 5G transmitters now. Still, the vast majority of people do not have cell phones that support high frequencies, so they are not used.

This has spread more than I thought. Initially, it was supposed to provide a couple of simplified explanations in Serbian to my friends who are not informed about the topic, and then it was set to “Public”… Most of those for whom I wrote this do not mean much information, texts and explanations in English, but since attention has increased, here is a discussion I participated in before publishing the post. I draw attention to a comment by user Imaccaro who gave nice examples that I checked, used and stand behind in this post:[https://www.reddit.com/…/recently_the_5g_causes…/] All the mentioned terms have been known since before the second half of the 20th century, and some even from the 19th century. The post is a summary of several physics’ lessons.
