A mac round by slower speed an less weight is STILL 10,000-1,000,000x LESS force than an asteroid even at 600-3000 tons each on mac rounds

Thermodynamic expansion and sheer kinetic energy alone would obliterate the shields. And it fires every 2-3 seconds lol (Super MAC odp) But that's not what I'll base the destruction of your shitty little Death Star off of. It's the sentinels... 1000 sentinels far exceed the destructive capability of the Death Star. Keep in mind that there are trillions of them and when they Conjoin their Firepower and forunner shields amplify [b]exponentially[/b]. Death Star would be a molten slag heap. None of the point defense systems or the actual primary weapon would breach their extremely overpowered shields.

Also keep in mind EACH SENTINEL is ONLY equipped with a heavy laser cannon (its not even on par with a TURBO laser from a capital ship in STAR WARS when fired in CONJUNCTION with others. And COVENANT vessels DONT have ray shielding (or to my knowledge ANY energy shields of ANY kind). I will run the actual numbers and account for thermal dynamics (though with a LASER or ENERGY based weapon the initial impact IS the strongest part of the reaction; lets not forget ENTROPY) ---> death star vs sentinel array An yea MAC rounds under SUSTAINED fire Might be on par with an asteroid impact but you would need to sustain fire FOR SOME TIME! (Keep in mind ANY asteroid impact is 500x MORE force/blast produced than A NUCLEAR WARHEAD of same YEILD!)

You misread.. Sentinel fire conjoined increases exponentially. Under the surface of onyx thousands of them firing in different directions destroyed the entire planet. Which in includes crust mantle core etc. which is far thicker than you 1 km Death Star armor. All covenant vessels have a primitive form of forunner energy shielding.. And primitive compared to the actual shields of the forunners they are quite strong. Standard shielding on a CCS class battle cruiser is sufficient to stop 3-4 plasma torpedoes then the nanolomite armor they use could tank two plasma torpedoes.. Ok back to the actual fight.. I'd say that 5000 sentinels conjoined would reduce the Death Star into a slag heap. Their firepower and defense skyrocket exponentially.. I'd say their combined fire would be on par with a gamma ray burst.. Death Star is dead. Accept it..

K thanx for the info on the covenant shields, will take into account. The death star's ray shielding though: Powered by a fusion reactor equal in energy output to a white dwarf star (roughly) the real question is can it get through that alone let alone 1-10km thick of super dense alloy (rocks and sand are less dense and less resistive than say a block of titanium of same size as an example) Ive got to do a SIZEABLE amount of research to run the calculations though and each number in each equation on average will consist if at least 10x place values, SO IT MAY BE A WHILE but I WILL POST IT on both this reply thread and in the MAIN TOPIC on this topic thread.

It won't be accurate.. Planet composition will not be accurate. Geophysics says that with acceptable gravity turns planets into formidable stellar bodies ( if that's the right word). Earth for example would be nigh indestructible in the physical sense. Everything on the surface would die in a catastrophe. But in real life what can you think of that would effectively destroy earth? Excluding out of system things. Supernova. Gamma ray pulses, etc. the core is a spinning magnetic crystal of molten iron. A nuclear weapon wouldn't do anything to that.. But again I'm distracted.. Sentinels are sentinels.. And this isn't really a fight of how but of how many. Sentinels are the very literal word of exponential. Every one of their strengths increase exponentially.. It would be a matter of how much your Death Star could take. And this is one thing out of the halo universe.
