Moon and Earth Collision

[BlackeJan]

I just want to know but how strong would you have to be in order to have confident in surviving a moon and earth collision?

 

[Psychomaster35]

You mean the Earth and Moon crashing into each other?

Depends on how fast they are going, but typically around at least Multi-Continent or higher

To survive one? You'd also need to take inverse square law into account. It would get a Tier 7 result if you're normal human sized roughly.

Oof. Even if u survive the after math of it all? (Explosion wise)

 

[DarkDragonMedeus]

It also depends on the kinetic energy the moon and Earth moved at, but explosions also use Inverse Square Law. Though it's usually in the Tier 7 to Tier 6 department. Though, this is also simply if it's just a durability feat; if you're the one who caused the moon or earth to clash, it would scale to AP. And thus likely scale to durability if they did it physically.

Is this for if a character is at the point of the impact or far away from the point of impact?

 

[DarkDragonMedeus]

It's if the target is too small to actually absorb the full impact. It's kind of light how some insects have survived getting hit by cars due to having tiny bodies and not because their sheer durability is that good.

Bump

It's more or less due to linear momentum, not necessarily inverse-square law. Same reason why you don't exactly scale to the car crash's full yield unless you get rammed into a sturdy wall and both you and the car come to a screeching halt and the car turns into crumpled metal into you. Gotta find your speed as you get flying first, then use your speed and body mass for KE and voila, you get the energy you personally took. Surface area has nothing to do with this, really.

Also we wouldn't use surface area anyway, we'd use cross-sectional area, since you're only imparting the force to one side of the body and not from the behind either.

Moon wouldn't actually hit the Earth, it would've been destroyed before touching the planet. But the actual KE is obviously Moon level.

Aye, just send it hurling faster than a tankshell (Roughly 1840 m/s) and you'll easily generate more KE than the moon's GBE. Ablation speed alone will do that.

But since this is the moon we're talking about, expect it to enter re-entry speed with a vengeance. That'd be at least 11 km/s, which is easily Low 5-B

[BlackeJan]

So what I’m seeing is between 5-C or Low 5-B(????)

 

[Scottycj256]

its either Moon or Small Planet i guess

 

[CrystalValley]

this may be a dumb question but i don't feel like making an entirely separate thread for a similar question.

if someone survived or tanked a moon being slammed into them at roughly around relativistic speeds, what would be the vague general estimate of durability required to survive or tank such a thing? i guess using the bare minimum of relativistic as the assumed speed.

Something something you'd need to account for the relative momentum between the object and the person if the collision crashes into the planet and destroys it and doesn't leave behind a strong-enough surface for the person to be able to reliably take the impact.

Basically find the speed the person was hurled at, then use that speed and person's mass for KE and you get the energy tanked.

PersonSpeed= (MassObjectHittingYou * InitialImpactSpeed)/(MassPerson+MassObjectHittingYou)

Then it's just KE: 0.5 * MassPerson * PersonSpeed^2

Tho beyond FTL applications, this goes to shit.
