Can We Discover a Unified Force Between Gravity and the Electroweak Interaction?

[ClamShell]

The electromagnetic force has been observed to
connect with the weak force to produce the
so-called electroweak force.

Is our next goal to observe a gravitystrong force?

Or a gravityelectroweak force?

Or a strongelectroweak force?

Or a srtongelectroweakgravity force?

 

[daschaich]

Your "strongelectroweak force" is more commonly known as a Grand Unified Theory (GUT), and has been under consideration for decades. The other three all require a quantum theory of gravity, which is a tall enough order all by itself.

[ClamShell]

When referring to a charge in motion we say
electromagnetic. Would it not then be analogous
to call gravity in motion, gravoinertial?

Thanks for the heads-up concept of GUT.

 

[daschaich]

Electrodynamics sounds more like a charge in motion. The analogous term for gravity is geometrodynamics, though I don't think it's too widely used in this day and age.

[ClamShell]

Let me put it another way. If we refer to
electromagnetic waves...would it be analogous, then,
to say gravoinertial waves instead of gravity waves?

IE, these waves have perpendicular components and
inertia seems to be perpendicular to gravity.

 

[daschaich]

It's not a term I have ever heard before. If you can find it on Wikipedia, please point it out.

[ClamShell]

Nope,
came up with it outa my own pea brain.
Gravitomagnetic waves are mentioned
in wiki...so maybe somebody might call
them gravitoinertial waves. Anyway,
what would the orthogonal component
be for a gravitational wave? Space, time,
space-time? Or would it be inertia?

 

[Dead Boss]

Or maybe there's no orthogonal component. Have you thought about that?

Reminder: PF exists to help students learn the current status of physics as practiced by the scientific community. If "gravoinertial waves" are a new idea, they don't belong here. If they are an existing idea with a new name, we should use the standard name in discussing them.

Dear Vanadium50,
If you have an opinion or knowledge of what the orthogonal
components of a gravitational wave are or would be, then
please share with us. Just trying to change the subject is
not fair. If, as wiki mentions, they are gravitomagnetic
waves in nature, then be constructive. My opinion is that
there must be orthogonal components for Maxwell's
explanation of EM waves to apply. This is an invitation
to join the discussion.

 

[ClamShell]

Maxwell's explanation of EM waves seems to require orthogonal
components for the wave to advance in space. Do you have any
evidence that a wave can move without an orthogonal component?

But gravity and electromagnetism are different forces, with different laws.

Yes, I am being draged, kicking and screaming, to the truth...
and am all the better for it...thanks muchly.

 

[Suk-Sci]

the distance till which the strong nuclear force is applicable is very small and gravity exerts force on everything...

 

[ClamShell]

Are you saying that this makes the strong and the gravity, NOT able
to be unified like the EM and the weak, or the opposite, or something
else?

 

[Suk-Sci]

Yesssss...

 

[Suk-Sci]

well an interesting thing is that some physicists are trying to include even SPIN as a 5th fundamental force...

 

[ClamShell]

The strong nuclear force CAN NOT be unified with the gravitational force,
because they are so different?

And, I guess, the EM force is similar to the weak force, then?

I can accept this, please continue...

 

[Suk-Sci]

i think we may be able to join the electromagnetic and gravitaional force as they both have a range upto infinity...

 

[ClamShell]

i think we may be able to join the electromagnetic and gravitaional force as they both have a range upto infinity...

EM is already joined with the weak...do you mean it can join with
both the weak and the gravity, or do you mean either the weak or
the gravity?

 

[Suk-Sci]

i mean weak or gravity

 

[ClamShell]

i mean weak or gravity

And strongelectroweak (GUT) is a dead end?

 

[daschaich]

The range of the forces is completely irrelevant. We already have a quantum field theory of the strong and electroweak interactions. It's called the standard model. We do not have a robust theory of quantum gravity, which will be needed before we can even think about unifying all four forces in a "theory of everything".

The Wikipedia articles I posted earlier have some information. Read them, and references therein.
