Heat from the Sun and the new "aether"

[Roshi]

How does the Sun heat the Earth if there is a vacuum between the two?

Answer:

Heat also transfers by radiation, which the sun is an enormous source of. Electromagnetic radiation does not need a 'medium' to travel through. All types of electromagnetic radiation carry energy, which can be transferred to other bodies when this radiation interacts with them. The continuous stream of photons from the sun is what transfers its 'heat' to us.

And radiation does not need a "medium" they say. There is nothing there.

Except this medium that can bend massless light rays (because the medium is itself "bent"), and also can apply a force to all objects with a mass (force comes because the medium is "bent").

Meaning - photons alter their course because of the bend in the medium, it does not matter if they have no mass. In this case, if even a photon that is this fast, tiny and massless thing cannot do anything else except follow the curvature of the "medium" (officially there is no medium), how can we fly into space by simply applying some force, and breaking out of the curvature?

And, how can a photon escape the curvature, and not fall on a star or planet if it passes near it, if just the curvature makes it change it's direction? Photon has no mass, meaning we can't talk about how much the curvature affects the photon, depending on it's mass.

Why then does a photon, once deviated from it's straight path - exit such a curve, that acted upon him just because the curve is there, independent of the photon? It just alters it's path slightly then goes on - straight? Why? While other photons alter their path more, then go on straight?

There is something fishy here. Distance from the object producing the curvature should have no effect on letting the photons continue straight after passing near a body, because we are not talking about 2 masses interacting, and we do not apply the universal attraction law formula. All photons in the Universe should move in circles because of this "bent space time".

Also, even without talking about this new aether medium ("no medium exists or is needed" is the official position, and even gravity waves - that are the waves of this new medium itself, need in fact no medium...), vacuum does not exist:
https://en.wikipedia.org/wiki/Vacuum_state

I think there must be a medium for light rays or radiation to travel through, and it's not "space time".

“I hold that space cannot be curved, for the simple reason that it can have no properties. It might as well be said that God has properties. He has not, but only attributes and these are of our own making. Of properties we can only speak when dealing with matter filling the space. To say that in the presence of large bodies space becomes curved is equivalent to stating that something can act upon nothing. I, for one, refuse to subscribe to such a view.”

Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields

They talk about waves, waves of what if "there is no medium"? Waves of the magnetic and electric fields. So - there is this field that oscillates, this means there is a medium.

Short:

"Space-time" de facto replaced the old "aether", even if mainstream says "there is no aether" (or other medium). Bent space time = gravity. Gravity waves = space time waves. Meaning a medium that itself oscillates or makes waves. Even if they say there isn't any.

But there are some problems with this "space-time", and I am sure another kind of medium should exist for EM waves.
