Why do gravitational waves or electromagnetic waves exist?

Maxwell equations or Einstein field equations imply the existence of electromagnetic waves and gravitational waves. How can these waves persist on (vacuum) space if they radiate (and loose) energy?

Are gravitational waves the slowest waves known to science?

Consider that two celestial bodies orbit have a frequency of one rotation every 50,000 years, it means that the periodicity of the gravitational wave sensed by a distant observer is about 50k years. ...

Is there a “magnetic gravitational” field? [duplicate]

Electromagnetic waves, in the classical sense, are due to oscillations in two different fields. They propagate at the speed of light, and they can be described by a set of differential equations. ...

Lowest 'Order' of Radiation

I've noticed an interesting phenomenon (admittedly from only two data points). In electromagnetism, $A^\mu$ obeys Maxwell's equations: $$ \square A^{\mu} = j^\mu . $$ where I've chosen $\mu_0 = \...

Would photons “riding” a gravitational wave appear different to an observer?

Gravitational waves travel at the speed of light. A photon travelling in exactly the same direction as a gravitational wave will therefore remain in exactly the same position relative to the wave - at ...

Can gravitational wave induce electromagnetic waves?

Moving charged particle produces a magnetic field. If a gravitational wave passes by stationary charged particle and makes it oscillate together with the space, would that movement produce an EM wave?

Effects of gravitational waves on light

My understanding is that light is curved by curvature in space-time lattice (that's why it can't escape a black hole, it is just too curved: I may be wrong). So how is light influenced by ...
