can we travel in time or many more .....???????

We always travel forward through time, not backwards, and we cannot change the laws of physics.

I suppose we can always travel backwards in time, by using memory and records.

 

And can't we change the laws of Physics, by using Relativity instead of Newtonian laws?

can we do time travel and....????

You can't change the laws of physics, only nature can do that.

but u should know that our laws are made by us

but the laws are made by us not nature but Newton and newton is not an god indeed

but u should know that our laws are made by us

No, they aren't, they are made by nature.

The laws of physics are not made by us. It is just that we discover them using scientific evidence and logic.

If you can change the laws, they aren't laws anymore.

Up to about 1890, Physics was run by Newton's very rational Lawa.

 

Then Einstein upset things, by bringing in eldritch new Laws, which physicists now use, with fingers crossed behind backs.

 

Will there be any more Law changes, or is that it, do you think?

Einstein did not change the laws of physics, he merely discovered nuances that Newton had not discovered. Newton's formulas still work for non relativistic situations.

Hm, Relativity is merely "nuances" that Newton hadn't discovered?

 

Surely you can't defend that!

Are you quibbling over the word nuance? Newton's equations still work at non relativistic speeds. Einstein discovered E=mc² as a result of his work, but it does not contradict Newton. It starts nuclear physics, which is in addition to all Newton discovered. Newton discovered calculus, which Einstein used. What is there to defend?

Relativity reduces to Newtonian physics in the limit of small speeds; basically the terms for KE and momentum, etc. are the fist term in the expansion of the relativistic expressions. It's not an unreasonable characterization.

With fingers crossed behind backs? No, not so much. I've never crossed my fingers, hoping that a relativistic effect will work.

Yes, accepted, which is why I thought it would be better put, that Newton discovered nuances of Einstein's theory, not the other way round!

Your ordering seems odd to me, since Newton had been dead for about 200 years before Einstein's theory, but both worked on the laws of motion and gravity. Einstein's theory is more complete.

Are you being wilfully obtuse? I'm saying that Newton's theory is a nuance, or subset, of Einstein's! Which is what you're saying!

 

These Americans, they're great guys, but no wonder they don't do cryptic crosswords.

Why get irritated? It's only a simple misinterpretation.

I have not intended to be obtuse. Newton lived about 200 years before Einstein; thus, Einstein started with Newton's laws of motion and gravity, and added scientific knowledge. Newton's laws are a subset of Einstein's. I believe we agree on the facts. I apologize for using the word nuance.

Newton lived about 200 years before Einstein. Thus, Einstein started with Newton's laws and increased scientific knowledge. Einstein's theory is a superset of Newton's. I think we agree on the facts. I apologize for confusing the issue by using the word nuance.

It means do not start multiple threads on this topic; you had many, many duplicate threads when you originally posted.

In Ray Kurzweil's book, The Singularity Is Near, he suggests that eventually we will figure out a way to surpass the laws of physics due to the fact that we will be much more effective and learn at an incredibly quick rate, but much-much farther down the road.

I do not have his book, can you quote his statement?
