Does anyone believe that laws of motion,force,ect. are consistant throught the universe? I believe that in different conditions theses laws may be changed slightly and sometimes done away with completely. What does everyone else think?
Same laws throught the universe?

wouldnt a lack or excess of gravity cause some of these laws to change

i agree wouldn't the reduction in the gravity in space compared to the gravity on earth affect any of the laws because think about it, when you go bike up a hill its harder, when you bike down its easier.. why is that because of gravity, so i believe that gravity does affect it in some way.
No, more or less gravity doesn't change the laws of physics. It just alters the input, the equation remains the same.
Like multiplying. If you multiply 5 with 4, you get 20. If you multiply 5 with 84 you get 420. It looks very different, but the same laws apply.

No, it doesnt change the law. think of the law more of a formula. g (gravity) is nothing but a variable, changing the gravity will change the result of the formula, but the law itself still stands. F=ma, (force = mass x acceleration) still applies, If you have a higher gravity, then "a" (acceration due to gravity) would be higher, so therefor you will have a higher force.
These laws of physics are universal, which means they apply everywhere in the universe. The only excepting would be black holes and such i would asume.
Why would black holes be an exception? Tell me if I'm incorrect, but isn't a black hole just a gathering of mass with an incredible gravitational field due to the sheer mass of it?
If my understanding is correct then gravity should function the same way here, just with a far greater impact on the formula.

Im not talking about gravity, there are alot of laws of physics other then gravity.
All the evidence ever recorded supports the assumption that natural laws are universal in nature. It is extremely improbable (to a massive degree) that 2 + 2 would ever equal 5 in another place.
Shredder I'm not talking about that kind of law. I'm talking about laws of physics, such as gravity, motion, force, ect.

I believe that there are other laws in universe about physics, because when I think about all the forces that give our Earth this all, then thinking about other planets - there can't be any Earths like us. There has to be atleast slight changes at physics.

Our laws and forces should be consistent.
Where did you get the idea that planets with the same physics are exactly the same? Do you think Mars has different physics than what we have on Earth?

Well, for example I learnt at physics lesson yesterday that the magnetic laws had changed for over 2000 years ago. 2000 years ago, the north of the magnetic field will show the compass to the north pole. However, the south of the magnectic field will show the compass to the south pole. It had changed.

Its all the same
Universal gravity:
G = 6.667 x 10^-11 N.m^2/kg^2
motion:
Any object which is at rest will tend to remain at rest. An object moving in a straight line will tend to do so unless acted upon by another force.
Force:
F = ma
These formulas are no different to 2 + 2 = 4
We have varying speeds of light right here. Scientists have been able to slow down light, without breaking any laws of physics.
That constant is the speed of light in a vacuum my friend.
