Physics Laws

Postby vrek » Mon Aug 13, 2007 7:29 pm UTC

What physics laws would you like to change? I don't mean like make gravity 5.6 or anything like that I mean like I would like to be able to reverse chemical reactions. For example lets say I fry an egg. I wish there was some way(albiet physically impossible) to un fry that egg if I change my mind on what I want to make.

I think slowing down gravity would be a great idea.

Imagine doing something like skydiving, but being able to control how slow or fast you fall without a parachute.

I was thinking science forum but I am not really asking any real science questions. I am just asking what you would like to break in physics/

Conscious control over gravity's influence over me, i.e. being able to decrease/reverse it's hold on only me, or being able to make it come from a different direction (flying!). Doing the same thing to other things in your surroundings would be fun as well. Would make a great superpower.

Yeah, I've thought about that one before. Even just being able to decrease gravity's influence on yourself to zero would be fun. (As long as you could increase it again. Otherwise you'd be buoyant and just float away.)

Also, if you've got the time and a lot of eggs to start with, you can unfry them by getting a hen and feeding her nothing but fried eggs until she starts laying the raw kind. :-)
Unless stated otherwise, I do not care whether a statement, by itself, constitutes a persuasive political argument. I care whether it's true.

But unless the hen lays eggs in at least a 1:1 ratio with the fried eggs you feed her, you still end up with net fried eggs. But I'm sure if you were able to destroy the laws of physics a 1:1 ratio would be possible.

For the "control gravity, make it pull me in other directions" etc. group, would this *just* be for you or would everyone/thing else be affected too? Presumably the first, but what if you could decide which? That would also be quite cool.

Oh, and I'd get rid of electricity and magnetism, because that's all magic.

Sideways interia. You push something, and it accelerates perpendicular to the direction you pushed it.

I'd like lenz's law to work in the opposite direction, so like a magnet could induce a current and then that current could accelerate the magnet in the same direction it was already travelling. Then we could have like cool perpetual motion stuff... and cool propulsion systems

I was thinking exactly the same thing....... Spontaneous rearrangement of particles would be fricking awesome. Admittedly I suppose one could become quite god like with it, but I'd like to imagine it'd be used for practical jokes- undressing people at awkward moments.....

I have suddenly pictured the most awesome sitcom: Maxwell giving speech to other scientists when his suit flies off... "DEMOONNN!" He yells! Cue canned laughter. Comedy gold.

Also, definitely changing the Second Law of Thermodynamics.
There is a significant chance that an artificial intelligence created within the next few decades will not value humanity and therefore will treat us as we treat animals. It would be awesome if xkcd mentioned this.

Another vote for fiddling with personal and objects' response to gravity. Firstly, you'd be able to fly. Secondly, turning gravity down a bit would be an awesome tool for learning new juggling patterns. Not to mention the mayhem you could create by having each ball fall under a different acceleration.

I would like the power to control quantum uncertainty on a very large amount of molecules at once. For instance, I would like to be able to say "all the quarks that make up that far-away lamp, make it extremely probable that they are all over here near me!" and save myself the trouble of getting the lamp myself.

This produces a paradox; specifically, that objects at rest start moving and immediately want to return to rest then immediately begin to move, ad infinitum.

By this (il)logic, maybe every object would continuously spasm as it tried to reach an unattainable equilibrium between motion and non-motion.

Is it really impossible to unfry an egg? I assumed it was just really hard.

I was interpreting it more as F= -ma. I.e. you push on an object and it starts moving the opposite direction.

Could not F=-ma potentially cause the universe to evaporate as anything that comes into contact with anything, rapidly unleashes infinite energy:

push something
it accelerates towards the pushing force, thus extering more force
it tries to accelerate harder
etc
etc
evaporate

Also, I like the feeding a hen the eggs that you want to un-fry, as the complex biochemistry of the chicken will (assuming they can actually digest fried eggs that is) will dismantle the cooked egg on a molecular scale and then construct a raw one out of said components, it might not be the same egg, but hey.

I'd like it if the Halting problem was O(log(n)) instead of undecidable.

That and if acceleration was classical instead of relativistic. FTL for the win.

Ah, damn. I was all set to choose the Halting problem before you showed up, zenten. Though I'd choose it to be in O(2^-x) time. That's right, baby, the more data you feed it, the faster it answers!

I would quite like absolute mental control of electromagnetism, even if it was only to the point of understanding exactly how it works. Better than gravity in my opinion, as it is much stronger and could be used to shoot lightning from your hands (thereby winning on the coolness factor). It could even be used for levitation.

The denaturing of proteins isn't exactly something that we conceptualize as an irreversible law. As the denaturing of egg proteins is pretty thermo-chemical in nature, it's not really universally impossible to reverse the process, you just have to fine-tune the science that we already have. To actually throw off one of the established laws of the universe, however, would probably make the universe stop existing in any coherent form.

Why all this talk of changing the second law of thermo dynamics? Why not the first law? Can you imagine all the things you could do if energy wasn't conserved? Well... anything!
The zeroth law is kind of annoying too sometimes. Like when your coffee is cold or your ice cream melts.
