Which laws of physics are violated if an object simply instantaneously appear somewhere else?
Dragonfall said:So you can't go faster than light, but you can just instantaneously jump to somewhere else (in principle)? Seems counterintuitive.

keinve said:that law stating nothing can go faster than light. if it's instant, it would go faster than light. assuming it goes no faster than light speed, none.
malty said:I thought though that "law" was actually a hypothesis so we don't know if it's true or not, we just assume it to be case.
ZapperZ said:There is no such category in physics, or at least such division isn't an issue. Newton's Laws certainly can't be called a hypothesis, or else your house, buildings, and bridges were built on nothing more than a set of hypothesis. I don't think anyone would feel secure with that.
In physics, we should not get hung up on the "names" that we give to things. Just understand the description and look at the degree of certainty them. If such a law, theory, etc. is being used to produce other stuff and it is well-used, then it is well-verified and has a high degree of certainty, no matter what label we attach it to.

I wasn't referring to Newtons laws though. I was referring to Kevinie "law" that nothing can travel faster than the speed light, I thought that was classed as an hypothesis which was postulated by Einstein. Of course I understand that Newtons laws can't be mathematically derived or proven they just work, as do many of our other natural laws. Every model which we use and describe in physics is based on either the natural laws, or proposed theories, I wholly accept that and I accept that we have just to understand their description but certainly we have also to accept the assumptions in our theory. Think back to the whole aether theory, wasn't Michelsons-Morley regarded as one of the failed experiments of all time? It seemed to call into serious doubt the existence of aether.
An assumption which many theories had used previously to explain the propogation of light.
My point to Keinve, (well my intended point anyways), was to point out that we must know when the difference when something is regarded as to as law and as an hypothesis and that you simply cannot regard the argument that an object cannot travel faster than c as a law until it is experimentally proven! We should distinguish clearly between hypothesis and fact, yes we should understand both and used them both to develop ideas and models of our universe and its contents but we should also accept the possibility of some of our arguments being flawed. At least that is what I believe we should do.

Why am I NOT allowed to use witchcraft; I WANT to use witchcraft.PhysiksFreak said:Teleportation...it's possible, but what would be the principle behind it? assuming you're not using witchcraft or anything.
PhysiksFreak said:Well - teleportation using magic/witchcraft is a bit damn difficult, and as for decomposing yourself, it would take a hell of a lot a time. I guess I'd rather just walk there. So - for using witchcraft to teleport - your mind must be strong and focused. I'm not going to tell you how to do it because I don't know my self, and I wouldn't want you to be doing the wrong thing.
PatPwnt said:I think it violates conservation of energy. If you teleport to anywhere else in the universe, your potential energy is going to increase or decrease. For example : say you have a portal at 50 ft in the air and one on the ground. If you walk into the portal on the ground and come out 50 ft in the air, all the sudden you gained potential energy. Where did the energy come from?
malty said:You're forgettinng though that potential energy is merely a measure of energy relative to something else, so walking into the portal makes appearing up a height of 50 ft mean nothing, because theoretically haven't actually changed your height; when you walk through the portal you must also threat the ground as having gone through the portal.
PatPwnt said:Imagine placing portals the same way directly above each other. You jump through one and fall into the next causing a loop. You will accelerate indefinitely (ignoring air friction). You could attain any speed you wanted to thus having theoretically infinite energy. This is all assuming momentum is conserved through portals.
malty said:I understand how you can accelerate, and but thereotically you can't travel faster than the speed of light, so you wouldn't have infinite energy because thereotically the faster you get the more matter you must absorb/create... E=mc^2 tells us that for an object if it can't reach c then it's mass must get larger if its accelates! So you may no longer be able to fit through the portal after a while!
[Ah someone already beat me here]

Teleportation does not currently exist, so it does not violate any laws of physics. However, if teleportation were to become possible in the future, it would likely involve violating the laws of conservation of energy and momentum.
The law of causality states that every event must have a cause. If teleportation were possible, it would likely involve breaking this law as it would allow for an effect (the person or object being teleported) to occur without a specific cause.
The laws of thermodynamics state that energy cannot be created or destroyed, only transferred or transformed. If teleportation were possible, it would likely involve creating energy to transport matter, which would violate these laws.
The theory of relativity states that nothing can travel faster than the speed of light. Teleportation, if possible, would likely involve instantaneous transportation of matter, which would violate this theory.
As of now, there is no scientific evidence or theories that suggest the possibility of teleportation. However, there is always the potential for new discoveries and advancements in physics that could make teleportation a reality in the future.
