time dilation

There's several reasons why nothing with rest mass can go ftl. If you could go faster than light, you'd reach your destination before the light that left at the same time as you did so you'd effectively be from the future. But, you can't actually go back in time.

>reach your destination before the light that left at the same time as you did so you'd effectively be from the future
What makes light special though?
If you ran faster than the speed of sound you'd get to your destination before the sound waves and be able to hear yourself coming but no one says that's impossible or makes you're a time traveller.

Suppose I don't believe human visited Moon. Let my argument be it is too far away (4 E8 meters) for that much weight (3 E6 kg). Current satellites of that time were 100x closer (3 to 4 E6 meters) and 100-1000x times lighter.

Distance from Earth to Moon (meter): 4 E8
Distance from Earth to satellites of that time (meter): 3 to 4 E6

Mass of rocket that is claimed to brought humans to Moon (integrale of kg per meter):
>3 E6 to 5 E4 from Earth to 2 E5 (at that point module was separated from carrier rocket)
>5 E4 to 5 E3 from 2 E5 to surface of Moon
>With 5 E3 from surface of Moon to Earth

Mass of satellites of that time (kg): order of magnitude E3 to E4

I accept that unmanned devices did land on Moon. Latest lunar orbiter had a mass of 4 E3, 10x lighter than manned spacecraft.

In anticipation to the most common counterarguments
>There is a reflective surface in Moon that the men installed. You can shine laser onto it
Unmanned device could've easily planted that. I accept that reflective surface of that kind couldn't have formed spontaneously.
>Why would they fake a moon landing?
Power display. USSR and USA were heavily influenced by competition that could've driven them to such acts.
>What difference does it make whether they were on the Moon or not?
Humans have unrealistic expectations on space transportation possibilities. I want to reinforce the concept that humanity will (1) never live on any other celestial body other than Earth (2) never be able to transport any instrument outside the Solar system (3) never find extraterrestrial life. These realistic expectations will possibly lead to better environmental policies.


In conclusion: I claim a human has never touched the surface of Moon and returned alive.

How would you attack my claim so that I myself could reproduce the results? Merit of science is that in principle anyone could verify what you say, and that for a claim to be true, it must also be verified by someone else (for example, not USA)

Oh god not you again. As was pointed out last time, that is not how orbital mechanics work. Getting to orbit is the hard part, and from there it doesn't take a whole lot more energy to get to the Moon or even other planets like Mars or Venus. The Moon being 100x further away doesn't make it 100x hardrer to get to.

>>9051948
>How would you attack my claim
I'd ask you to actually provide some evidence, rather than waving around numbers without considering what they mean.

I took noopept, phenylpiracetam and some choline.

Didn't do shit and I don't recommend nootrpics to anybody.

Just sleep well, eat healthy and your brain will thank you.

The physicists at the Hadron collider have already made black holes, they're only seen for an instantaneous measure of time because they're really fucking small.

people who believe in religion are generally happier
whats your goal here?
Also there's nothing scientific about not believing in god

your primary focus should be getting them to look past your beliefs rather than proselityzing it

>>9056433
In my view at least, atheism is more scientific.

But I'm totally fine if they want to be religious.
My main goal is to at least get them thinking scientifically. So, off the 6000 year old earth and "Science doesn't know evolution happened for a fact" logic.

Inb4 Americans meming with FUD they were taught in public school.

Most are fine. Herpes is asymptomatic in most people. You can get HIV and live a long happy life. You can be immunised against HIV. Others are dealt with by antibiotics, until those are ruined by Chinese cattle farmers.

Literally a non issue these days.

Immunised against HPV, rather.

Is that really how they are ranked? That's stupid, they should rank them by golds, then silver, etc.
