Who cares about such a universe? It isn’t this one and we don’t have access to it to test any claims about it. Any statements you might make about it are not scientific.Altair Tans said:What if there is a universe with just one point charge in existence....just a charge with vast emptiness around it
If all laws of physics are the same then clearly fields and energy are defined.Altair Tans said:now here all laws of physics remain same...
But is the concept of field and energy defined there?
Hi, there are actually plenty of problems I had to do regarding this in my electromagnetism class. If you look at calculations involving Gaussian surfaces as well as coulomb'a law it should answer your question.Altair Tans said:What if there is a universe with just one point charge in existence....just a charge with vast emptiness around it....now here all laws of physics remain same...

Aren't fields defined in terms of forces acting on a test charge, and how is that possible if there are no other charges?Dale said:If all laws of physics are the same then clearly fields and energy are defined.
In vacuum there are no charges, but there are fields. Your definition is a little wrong.greypilgrim said:Aren't fields defined in terms of forces acting on a test charge, and how is that possible if there are no other charges?
What are fields there for then?Dale said:In vacuum there are no charges, but there are fields. Your definition is a little wrong.
I am speaking in the sense that like if there's just one object in an empty universe its motion is not defined. Its moving or at rest is not defined as long as there's no frame to refer with.Altair Tans said:What are fields there for then?
What do you think? What things are associated with the fields that might cause problems if they didn’t exist in vacuum?Altair Tans said:What are fields there for then?
You stipulated a one-charge universe where all laws of physics remain the same as ours. There is a charge so by Gauss’ law there is a fieldAltair Tans said:I am speaking in the sense that like if there's just one object in an empty universe its motion is not defined.

Similarly i believe without something to act upon the concept of force , field of force and energy associated with the force are all invalid.
Am i wrong somewhere?
How can we possibly know if your understanding of single charge universes is correct? I have no evidence to contradict your claims and you have no evidence to support them. There is no possibility to use the scientific method to answer such questions.Altair Tans said:Ok so there is a field, there is energy associated with it, but these quantities don't get a chance to be in use.
Is my understanding correct sir?
As @Dale says. This is a "tree falls in the forest" situation. Does it make a sound? It doesn't matter. Pick whichever answer yields a simpler theory.Dale said:How can we possibly know if your understanding of single charge universes is correct?

A universe with one point charge is a theoretical model used in physics to study the behavior of a single electric charge in an infinite, three-dimensional space. It is a simplified version of our own universe, where all other charges and objects are assumed to be nonexistent or negligible.
While this model may seem simplistic, it allows scientists to study the fundamental principles of electric charges and their interactions without the complexity of other external forces. This can help us better understand and predict the behavior of electrically charged particles in our own universe.
Some key principles that can be explored in this model include Coulomb's Law, the electric field, and the electric potential. Scientists can also study the movement and trajectories of charged particles in this simplified universe.
In our universe, there are a multitude of different charges and objects that can interact with each other through electric forces. In a universe with one point charge, all other charges and objects are assumed to not exist, allowing for a simpler and more focused study of the behavior of a single charge.
Studying this model can help scientists develop a deeper understanding of electric charges and their interactions, which can have practical applications in fields such as electronics, energy, and materials science. It can also lead to further advancements in our understanding of the universe and its fundamental laws.
