What kind of energy can travel through empty space without being carried in or by any matter?

Moving is a relative fact: an object moving in a reference system (for example a train as observed from the station by a still observer) can be still in another reference system (for example the same train as seen by a car moving with the same velocity).
What is relevant is to accelerate (for example to start a movement in a reference where the object was still or to stop it). To accelerate a force is needed.
In empty space accelerating is essentially possible due to the so called momentum conservation law.
It states that the product of mass by velocity of an insulated system (no relation with other systems) cannot change in absence of forces.
Let us consider a car on a road: the force rotating the wheels comes from the car: it cannot directly change the car velocity. However, the contact between the wheels and the road causes a reaction from the road due to attrition. This is an external force: the car is not an insulated system and it can accelerate or stop.
In empty space this kind of propulsion is not possible.
Let us consider a rocket. Due to the action of the engine it trows out a mass (for example m1) in unit time from the jet at a speed v1.
The system before expulsion has a momentum (m+m1) v, where m is the rocket mass after the expulsion and v the rocket speed before the expulsion.
It has to be equal after the expulsion, thus, calling v2 the speed after the expulsion and considering that the mass m1 have a speed -v1 (opposite to the rocket direction) it is
(m+m1) v = m v2 -m1 v1
thus the velocity after the expulsion is v2=( (m+m1) v+m1 v1)/m > v. An acceleration has been obtained and the rocket increases its velocity :-))
The expulsion can be due to different causes, it depends on the used engine. Generally it is caused by a liquid fuel used in a turbine.

What is the release of light energy by particles of matter that have absorbed energy?
"phosphorescence"Scattering is the release of light energy by particles of matter that have absorbed energy. The transfer of energy carried by light waves to particles of matter is absorption.
The matter through which waves transfers energy?
The matter through which waves transfers energy is a medium.
What kinds of energy travel through matter?
Heat and light energy travel through space and matter
What is rhythmic movement that carries energy through matter or space?
A wave is a rhythmic movement that carries energy through matter or space.
Energy that is not converted into useful energy is given off as?
Depends on the context - however with stellar fusion much of the energy is carried away by nutrinos. These fundamental particles have very little mass (almost undetectible) and pass through ordinary matter. Trillions of nutrinos have passed through your body while you were reading this answer.
How can waves transport energy without trasporting matter from place to another?
When the waves travel through solids, liquids, and gases, matter is not carried along with the waves. The energy is then passed from molecule to molecule as the wave spreads out.
Why sound is not considered matter?
Sound has no mass. Without matter, there can be no sound. Sound is information which is carried on a wave that moves through matter.
How energy transferred through matter?
energy is transferred through matter or space by
Are sound waves in solar energy?
No, sound wave is translating wave of the matter. The solar energy is the wave carried by photon which is an energy (non-matter). There is no way a sound wave would be carried in the stream of photon.

What is rhythmic movement that carries energy through matter or space?
A wave is a rhythmic movement that carries energy through matter or space.
You can detect energy only by the effect it has on matter?
You are made from matter, and therefore would not be able to detect energy without it having an effect on you. Energy is defined as the capacity for doing work. Without work ever being done on matter, and without energy ever being defined this way, energy would not be detected.

What can cause a matter to change?
through energy and inertia the matter changed.
What do not need matter to transfer energy?
Energy can travel through empty space as electromagnetic waves (light, etc.), or as gravitational waves. Changes in the electric and magnetic field are also energy transfers without matter. However, please note that any energy has, by itself, an associated mass.
