Yea, this is what's kept me up all night.
(EDIT: To anyone that might find this, I spent
ALL NIGHT looking into this, so
PLEASE pay attention.)
Hearing about the Arcanopulsate Reactor's incredible heat, I tried to look for a number for its temperature. Unfortunately, I found nothing.
Instead, I decided to find John's temperature threshold.
Now, when a space shuttle reenters the atmosphere, it's going at
17,500 mph (7.8 kilometers per second) (Mach 22.98957987124636).
<1>According to this page
(here), the shuttle would experience temperatures of up to
7,800 K (13,580.33 F).
Why so high?
It's because of a mathematical coincidence used by heat shield designers, to estimate peak shock layer temperature.
Basically,
.1 km/s = 100 KelvinTherefore,
7.8 km/s = 7,800 K (13,580.33 F)Of course, according to this page
(here), the heat resistant materials can only reach a temperature of up to
1,600 K (2,420.33 F).
Now, let's take it a step further by using something that better fits John's size and wind resistance.
Now, we use the Stardust with a PICA heat shield.
<2>The
300 kilos (661.38 lbs) spacecraft is much closer to John's weight and size.
It traveled at a speed of
27,738 mph (12.4 km/s) (Mach 36.43915410617841).
<1>If we follow the same formula, then we'll find that the Stardust reached a temperature of
12,400 K (21,860.33 F).
According to this
(here), the PICA shielding, can only take up to 5,000 F.
This led me to the conclusion that the air around the spacecrafts reach up to 10,000+ F, but the heat shields must be good at repelling heat, but only up to a certain point.
The PICA shielding was created in
2007, so how well would heat shielding perform in the year
2557?
For this, I tried to find the temperature of a HALO Plasma Pistol.
Unfortunately, I only found the Plasma Pistol's power output of
150 kV @ 3 mA (45,000W).
<3>The problem is, in order to find the temperature of the plasma shot, I would need to know the plasma's density and how long John is exposed to it.
In the end, all I know is that John can be in places that are over
12,400 K (21,860.33 F), but not for too long.
I don't know how good his heat shielding is, so I have to leave it up to the imagination.
The original Space shuttle took flight in
1977.
<4> That's when it's shielding could protect it from temperatures of up to
3,000 F.
<5>In
2007, the PICA heat shields were developed, allowing spacecrafts to withstand temperatures of up to
5,000 F.
<6>Taking all of this into account, I thought of a way to guesstimate how advanced John's heat shielding would be by simulating the progression of technology.
There's a
30 year gap between both heat shield technologies and a
2,000 F gap between their temperatures.
John's suit was made in
2557.
Therefore,
2007 - 1977 = 30
2,000 F / 30 years = +66.66 F per year
2557 - 2007 = 550 years
550 years * 66.66 F per year = 36,663 F + 5,000 F = 41,663 FUsing that, John's heat shields would have a maximum safe operating temperature of
41,663 F, meaning that John's suit can conduct that much heat before it starts to fail.
If that's the case, and if wedo the same to the air around the spacecraft, then we find that he might be able to survive area temperatures of over
120,133.33 F, just as long as his suit can stay within the bounds of
41,663 F, but I'm not sure whether or not that's too OP.
He
is from the future, and MJOLNIR armor is said to cost more than a small starship, but is it too OP?
If so, then what temperature threshold would you recommend?
Just to put things in perspective, a nuclear blast has temperatures that range from
10,340.33 C (18,644.594 F) to
well over 10,000,000 C (18,000,032 F).
