The Powder Toy

I am the Big Bang itself. I rapidly expand and become the universe. Side note: there was no "next to the Big Bang", for it happened everywhere simultaneously.   The next user is trappe...

@NUCLEAR_FOX (View Post)  Actually, it appears to be a triple star system. There's Alpha Centauri A and B, and then there's Proxima Centauri which is close enough to have an orbit arou...

I am in my secret base on Pluto.   The next user is on Pluto's moon Charon without a space suit or base. You are completely unprotected against the vacuum of space and the extremely cold Ch...

Fortunately, there happened to be some water in the path of the bullet. On impact with the water, he bullet shattered into tiny fragments which immediately slowed down to harmless velocities.   ...

At least in theory, it could. In practice, there is the huge problem of generating enough antimatter to be useful for anything other than research or PET scans. The problem lies in the fact that to o...

@vinster7 (View Post) I did not see any specification on the amount of fuel that the space shuttle orbiter itself could carry, so I used the brown external tank instead. That tank was capable of car...

I died in a parallel universe. I am still alive in this one.   The next user has a lethal amount of mercury azide in their bloodstream. If you move too much or fall, it will explode, instantly k...

Fortunately, I am a self-replicating organism. As a result, only one of my clones exploded, and the rest of them kept replicating themselves.   The next user somehow impaled themselves on a nucl...

Well, one thing I do on my spare time is studying nuclear and particle physics. That's how I learned about the reaction products of antimatter annihilation. As for the theoretical total amount o...

One gram of antimatter annihilating all at once would produce a theoretical yield of 1.7975e+14 joules thanks to E=MC^2, or roughly equivalent to a 42 kiloton nuclear explosion. In practice, at ...
