Agreed, I'll look for an Earth-Moon one and I'll draw in a trajectory

It's possible that you could use the Moon to harvest the energy from Earth's rotation instead, which may end up adding to the moon's orbital energy (causing it to escape Earth's gravitational sphere of influence).

comment Why is the singularity of the Big Bang not considered to be the center of the Universe?
Or did the original $1m^3$ volume somehow vanish or disappear onto a different dimension?

comment Why is the singularity of the Big Bang not considered to be the center of the Universe?
Are you saying that the big bang happened in a fourth spatial dimension? If not, I think the balloon analogy falls short. At one point, the universe occupied $1m^3$. Then it expanded to $10m^3$, while fully encapsulating the volume of the original $1m^3$. Why is it not accurate to find 'where' this original $1m^3$ was in relation to the current universe, and call that the center?

comment Is there any difference between fusing and smashing particles?
I was referring to stellar fusion with H + H => He, and did not specify the isotope. Or were you saying that the 'stable' qualifier is incorrect?

comment Is there any difference between fusing and smashing particles?
It is not just about stability. Two nuclei => hundreds of stable Hydrogen nuclei is still not fusion. Put simplistically, you're either combining nuclei (Fusion), splitting nuclei with neutrons (Fission). Smashing things together can do either of those, or neither (energy production, misses, breaking nucleii with momentum).

In short, though perhaps not without some exceptions, the 'products' of Fusion will be more massive than its 'reactants'. The products of a Particle collider, if there are any stable products (it could in theory be 100% energy), are less massive than the 'reactants'.

Indeed! I meant 7% / 0.07, not both.
