@navyhato fucking women. first they cause the problem then they want everyone else to solve it. they deserve nothing and shall get nothing. enjoy then bed you made.
Oh how fun @Roscoesrevenge ! Even though you deleted your comment while I was having fun solving this differential equation, I still think you could benefit from seeing the results!
The false dichotomy aside, let's see if we can calculate just how wrong you are! I haven't done a calculation like this since uni but as long as we can find all variables this should be pretty straight forward, luckily the apollo missions are some of the best documented projects in human history (found all I needed immediately. Apollo spacecraft specs: https://t.co/lS0TVYoxTL [1], radiation levels, path, duration of exposure etc: https://t.co/txDCIk8dA1 [2] ).
So to solve this we would use the beer-lambert formula for radiation attenuation, so:
I = I_init * e^-μρx
where (only metric because ffs america):
I: Intensity of radiation after shielding (rem/hr)
I_init: baseline radiation (no shielding, rem/hr) [2]
μ: mass atenuation coefficient for aluminium (0.2 cm^2/g)
ρ: density of aluminium (2.7 g/cm^3)
x: thickness of the shielding (≈4 cm) [1]
Now to calculate intensity we can calculate the avg Dose rate using the atten. dose rate in inner/outer belt and exposure time for the astronauts, so:
dD/dt = ((I_in * t_in) + (I_out * t_out)) / (t_in+t_out)
where:
dD/dt: derivative of D_tot with respect to time t (i.e dose rate, rem/hr)
I_in: dose rate inner belt (10 rem/hr) [2]
I_out: dose rate outer belt (5 rem/hr) [2]
t_in: duration in inner belt (0.88 hrs) [2]
t_out: duration in outer belt (1.5 hrs) [2]
With this we can calculate the totas dose where :
D_tot equals the integral from zero to t_tot of the derivative of D with respect to t, dt. Which gives:
D_tot: total radiation dose recieved (rem)
dD/dt: Dose rate
t_tot = t_in + t_out: total time in radiation belts (hrs)
Ok we have defined the equation now we can just pop the variables in and do the calculations! First the beer-lambert equation (I = I_init * e^-μρx) (e = eulers nat. logarithm = ≈2.72, because math is beautiful and the universe is full of wonders)
-μρx = -(0.2) * (2.7) * (4) = -2.16
e^-2.16 ≈ 0.115
So:
I_in = 10 * 0.115 = 1.15 rem/hr
I_out = 5 * 0.115 = 0.575 rem/hr
Which gives an avg. Dose rate
dD/dt = ((1.15 * 0.88 ) + (0.575 * 1.5)) / (0.88 +1.5) ≈ 0.787 rem/hr
So the astronaut in the apollo spacecraft was exposed to:
D_tot = 0.787 rem/hr * 2.38 hours ≈ 1.87 rem
And that's our answer! 1.87 rem in total! which is absolutely nothing, the lethal dose for a human is about 500 rem! (https://t.co/vdlshDuPYg)
This has been a tremendously fun little exercise and I have enjoyed myself thoroughly!
Now, you are welcome to take this calculation (don't forget the sources!) and show to every one of your little tin-foil hat friends and let them check my math to make sure I haven't made any mistakes, but other than that I think I can conclusively say that the "impossibility of passing through the Van Allen belts alive" is pure horse-cock.
Thank you for coming to my ted talk.

@arkangeljoy you're muting because you're running away due to the enormous backlash to your woman hatred. don't lie you fucking snake.

It’s worth taking a moment to appreciate just how thoroughly we’ve won on the trans issue. Five years ago most people were terrified to vocally object to any of this madness. Trans activists were getting their way everywhere and in every area of society. Today the voices objecting are significantly louder than those supporting it. Laws have been passed in dozens of states outlawing child mutilation and mandating sex segregation in sports. Democrats politicians are embarrassed to talk about trans issues at all. Corporations are suddenly shy about waving the trans flag. Medical organizations are finally starting to admit that “transitioning” children is a bad idea. Anyone who claims “trans women are women” is guaranteed to get dogpiled and mocked. The trans agenda has lost battle after battle. Trans activists are a punchline, ridiculed and not respected by anyone. Conservatives have never flipped the script on a cultural issue this quickly and completely.
@JoeBiden haha this is just pathetic. well done giving the election to someone who you claim to think wants to be a dictator. very smart of you. dumdumb.
@realChrisBrunet my girlfriend is a congolese immigrant and we both want much stricter immigration. we understand that open borders and irresponsible policies hurt the people who are coming legally, and it hurts the entire society.
@thebfgvez@elonmusk antifa should still be labeled as a terrorist organization. what he registered as doesn't matter. the fact that he wants to kill the president because he believes he is fighting "fascism" is what matters.
