Strange they misser that. As a kid when Star Wars came out it was obvious to me and my friends it wssn the equator trench
What I missed as a kid was how dumb it was to have to wait for the Death Star to "clear the planet". It's a giant planet destroying laser. If the planet is in the way you blow it up. Then blow up the moon, assuming blowing up the planet didn't take the moon with it.
That’s not really that dumb. The Death Star is powerful enough to blow up an Earth-sized mass of rock, but Yavin Prime is larger than Jupiter. If they could blow it up at all, it might have taken longer to do than just rounding the planet. Or, it might have been impossible to do safely at a range close enough to do it. Additionally, recharging the Death Star takes some time so even if destroying the gas giant was as fast as destroying Alderaan, the rebels might have gained enough time to flee.
The planet’s a gas giant. Not clear what the superlaser does to such a body. Maybe not enough to harm the moon before the rebels have time to evacuate. Maybe it’d be dangerous to the Death Star, as well.
Yeah. Gas giant = lots and lots of hydrogen. Hit hydrogen hard enough and you can initiate a fusion burn--and while the fusion burn in the sun's core is peaceful enough it's very sensitive to temperature. Supply enough energy at one point and you can make it run fast--and propagate for a while. I rather think firing on a gas giant makes a mighty big boom--Yavin Prime, the rebel base and the Death Star would all die.
(Note that I'm talking energy densities far above a normal hydrogen bomb. The temperature/pressure required for a runaway fusion burn in deuterium-tritium is far below that required in plain old H-1.)
Maybe so, but Jupiter has been regularly impacted by meteoroids and comets with huge amounts of kinetic energy to little effect. Of course such events pale in comparison to the binding energy of a planet like Earth, which is approx. 60 trillion Gt TNT, which if I've calculated correctly is almost 9 quintillion Tsar Bombas. But if that's the Death Star's normal output, it would need to be 10,000x as powerful to completely blow up Jupiter. Who knows, maybe that's possible if the fusion reaction produced by the Death Star automatically scales up according to the mass of its target. But then I suppose a problem might be that such a large explosion could catch the Death Star itself in its blast radius, shockwave, or lethal particle shower.
Yeah, gravitational energy isn't enough to cause the sort of runaway reaction I'm talking about.
I'm not talking about the target increasing the energy of the Death Star, but whether the energy of the Death Star's weapon can initiate a runaway fusion reaction. Does Yavin simply go up like Alderaan, or does a good chunk of that hydrogen fuse to helium and fry everything around?
