Am I right when I say that you can orbit the photon sphere and still be not pulled towards the Event Horizon but you need to orbit (In your spaceship) at the speed of light?
The Photon Sphere is a theoretical region in space where photons (particles of light) can orbit around a black hole. This is possible because the intense gravity of the black hole warps the fabric of space-time, allowing for stable orbits of particles.
The Event Horizon is the point of no return for anything that enters a black hole, beyond which escape is impossible. The Photon Sphere, on the other hand, is a region outside of the Event Horizon where photons can orbit. It is not a physical boundary like the Event Horizon.
The size of the Photon Sphere depends on the mass of the black hole. The larger the black hole, the farther out the Photon Sphere will be. For a non-rotating black hole, the radius of the Photon Sphere is about 1.5 times the radius of the Event Horizon. For a supermassive black hole, the radius could be several light years.
In theory, any massless particle could orbit in the Photon Sphere. However, since photons are the only known massless particles, they are the only ones we know of that can orbit a black hole in this way.
The intense gravity of the Photon Sphere causes light passing through it to become distorted and redshifted. This means that the wavelength of the light is stretched out, making it appear redder than it actually is. This effect is known as gravitational lensing and is commonly observed around black holes.
