Yes, which is how the weapons essentially work, small masses have their masses decreased even further and are launched out of the weapon at high speed. The Mako is another good example, when it's dropped, the E-0 core reduces the mass of the vehicle so it doesn't splatter when it hits a planet surface.

so momementum could be absorbed becuase of the reduced mass by the mass of the Mass releay.  I think we could have just solved the whole thing lol

Mass Effect fields reduce the effective mass, and they can also increase it somehow.

Eezo doesn't exist in the real world, so arguing with the reasonability of anything relating to it is pointless.  Beautiful, right?

If the ship transferred some of it's momentum to the relay every time it jumped the relays would move very slowly away from their initial position, the ship itself would also suffer some crazy effects from the sudden gain or loss of momentum.

However it does make an interesting mental and theoretical exercise and could relate to future advances in Physics (Dark Energy/Matter, Gravity, Special Relativity, Unified Model etc.)

unless the mass releay turned the momentum into energy... who knows the point to the whole thing is that without  ability to replicate this kind of technology (which doesn't exist thankfully) then we could argue about it for all enterity and it would never be solved.  Momentum to energy and energy to momentum... lol

[Hunt3rW0lf]

Unfortunately Energy and Momentum can't be changed into each other, they're related but they're different factors, similar to charge and magnetism.

No, horrible. The same can be said of video games, books, characters, and most of science.

Video games are fake, so why play them, get them, discuss them, they are totally pointless wastes of time.

Books, see above.

Characters, same as above.

Science: Most of any advanced field of study (physics, biology, chemistry) are all about deducing what reality is since we cannot actually know. The model of the atom is just a model that for the information we currently have works. It may not be at all as we depict it.

The same can be said for advanced physics. A lot of it is just numbers, possibilities, etc. A lot of it may not exist as we have never seen it, it just is possible due to the math. So, since it doesn't exist in the real world, arguing its possibilities is useless right?

oh well maybe it is a field we don't understand lol again we just can find out.

Just a quick question is momentum a form of KE

Eezo is shorthand technobabble for exotic matter, an unproven concept in physics.

Oh ho, now the last bit you are completely wrong. there is a reason all energy is called ELECTROmagnetic radiation. And the concept is ELECTROmagnetism. c=E/B where c is the speed of light, E is the electric field and B is the magnetic field. B induces a current and a current induces B.

 299,792,458 is the current known value for the speed of light in a vacuum. As has been said, this is the absolute maximum speed light can go, it can only go slower.

The speed of light can vary depending on the medium, but c (approximately 3x10^8ms^-1) IS constant.

Of course c is constant, but does light always obey c, even in a vacuum?

I've never seen that equation before, source? My argument was that the relationship between charge and magnetism can be related to each other but they aren't transferable factors. Charge can be passed between objects and a magnetic field only effects and is effected by other objects.

Nope, light very rarely will travel at the speed of light in space due to the effects of gravity. I've never heard of the Scharnhorst effect but it relies on virtual particles and has a tiny effect on the speed of light. As we can never be in a gravity free zone, the value of c will be higher than it has been calculated to be.

It's the derivative of kinectic energy. mv = d/dt [(1/2)mv^2].

[Hunt3rW0lf]

Kinetic Energy is calculated by the equation Ek=1/2*mv^2, momentum is given by the equation p=mv (Ek is KE, m is mass, v is velocity and p is momentum), so you could write that Ek=1/2*pv. They can be shown to be linked but they are not the same factor.

so it can be converted back to energy following a similar forumal, just that there will be a converison  some energy to heat or other form of energy

You must also consider the possibility that gravity will somehow be found to be bipolar in the future. We've also verified that it travels in waves, so there are some assumptions that can be made from that.

You misunderstand. There's no physical conversion, it's just a computational one. We're not talking about a physical transfer of energy, just different equations explaining the motion of a particular object.

To find KE, you simply integrate P wrt time.

I know there will be a loss of energy but it can stil be transformed to energy??

[Hunt3rW0lf]

Not really, there is no way to convert momentum to energy as it is a factor of energy, the more momentum an object has the more Kinetic Energy it has, so anything you do to the Kinetic Energy of an object will effect the momentum.

Yep, I definitely believe that there could be negative mass and ergo negative gravity which leads to the conclusion that the speed of light could be increased beyond the constant value.

The entire history of FTL theory has been humanity beating its head against a wall we've finally found that we don't know how to break. I think it's very entertaining.

From the Mass Effect Wiki:

Mass relays function by creating a virtually mass-free 'corridor' of space-time between each other.

So the eezo core of the mass effect relays is powerful enough to reduce the mass of space-time between two points possibly hundreds or thousands of light-years distant to virtually nothing?

Conservation of energy with respect to momentum does however determine the distribution of energies in particle collision.

[Iamoncewas]

oh so this whole talk has been about the KE of an object traveling in space instead of momentum??? if the KE can be captured by the mass Realy and stored just like the heat in the sinks of the Normandy can we assum that the technology could be the same.

Unfortunately Kinetic Energy isn't something that can just be captured, unless you want to strap dynamos onto the side of the relays for incoming ships to latch on to (and no, I really doubt that's what the rotating rings in the centre of the relay are!)

[Iamoncewas]

just sayin, again, we can't test it yet so, we'll have to wait for a while.

[TheGuv]

Just as a question, how many people talking about this are physicists?
