Redemption, Part 2 Physics

[P014K]

Hello, I came up with a physics based explanation of why

Spoiler:

the Stargate could not be lifted while it was receiving a ton of energy from Anubis's Stargate destroying weapon.

Tell me what you think.

So by Einstein's formula E=mc^2, mass is proportional to energy, if the gate had increasing energy, it would thus gain mass. Therefore, the if the energy it recieved was 200 megatons as Carter had said, then the gate would have gained a ton of mass. So, they could not lift it out of the base. Furthermore, it would start to sink into the foundation as time went by. And, even if the crane was strong enough, the X-302 couldn't carry it out of the atmosphere. The SGC was already pressed on weight issues with the X-302 anyways.

Feedback?

You have misunderstood the meaning of the formula. Energy doesn't have a mass. Energy is made of photons, which are massless particles. ( http://en.wikipedia.org/wiki/Photon )

How ever, mass can be turnet into energy and likewise, but they don't share each others properties. ie, you can walk through energy, but not through a brick wall.

naquahdah stores energy as neutrons, so hes right

[Semmer]

naquahdah stores energy as neutrons, so hes right

Neutrons??

[thekillman]

yea its true. it absorbs neutrinos and stores the power as neutrons

The answer to this was given in the episode, the Stargate is just too damn heavy.
The X-302 is a fighter, not a cargo ship. It was never designed to carry that sort of weight and would've had the same problems had the Stargate been deactivated at the time.

Weight of Stargate > X-302 lifting power

Simple as that...

[thekillman]

the energy increase of the gate wouldve certainly enhanced that. but yea, i believe its some 30 tonnes?

[P014K]

Neutrons and neutrinos both have mass, so the energy that is provided by the
naquahdah would increase the mass of the stargate.

[thekillman]

thats my point?????

but the gate was already terribly heavy. so it was barely liftable, with the energy buildup even more

[Mister Oragahn]

64,000 lbs was the mass of the stargate, but now you make a good point about if this represented the dry weight, or the total with the energy. Depending, of course, what kind of energy we're talking about here.
Where is it said that the stargate absorbs neutrinos to store energy as neutrons?

[Zatnikitelman]

HOW could the energy be pure mass? Since when has it been said IN THE SHOW that the 'Gate stores energy as neutrons and neutrinos?? Energy doesn't take the form of massful particles neccessarily. Do you gain mass when you raise yourself above the Earth? Does an airplane gain mass when it is cruising at 30,000 feet above Earth? Does the space shuttle, gain mass just because it is 200 miles above Earth? If it does, then it is so small it's probably not even measurable except in equations (which are not a measurement so much as a really good guess based on other knowns).
This crap on these forums is becoming rampant. You people seriously need to check your facts before you go off spouting some wrong information!

Naquadah is said to interact with neutrinos and become energised by them. However, interact does not necessarily mean it captures them and stores them, or indeed converts them into neutrons (and frankly, the neutron is about the worst particle you would want to store any kind of energy as...).

Besides, this line was a throwaway from the very early days of SG-1 - it may even have been Children of the Gods, and it is, frankly, nonsensical technobabble. Writers picked a then current scientific buzz word and ran with it.

As said by previous posters, the naquadah has energy in the form of neutrons and neutrinos, which have mass, therefore E=mc^2 applies

In all these situations you have said, the systems are not gaining external energy, as the stargate was through Anubis's machine. The energy your referring to here is potential energy due to height.

Energy does exert a gravitational effect. This was the great prediction by Einstein that allowed relativity to be tested experimentally and confirmed, and which separated it from Newtonian physics.

[Mister Oragahn]

Oi people, the stargate can only gain mass if it transforms energy into matter (which it wasn't doing at that time) or if it "simply" catches matter, like neutrinos.

So, back to square one:

Where is it ****ing said that neutrinos are caught by the stargate and altered to store energy?

Thank you.
