Can you make an educated guess on the amount of energy in the universe in the form of electromagnetic radiation (photons), considering the vast amount of photons moving in every direction throughout the vast universe, there is literally no point in the universe that you can be in and not observe...

Can light be bend in such a way that it is essentially trapped in an orbit?

If you interact with a moving object in space so you can draw energy from it you'll slow it down in the process. So no perpetual motion there either. If you could wrap a coil in space around Earth you could use the rotation of Earth and it's magnetic field to produce large amounts of energy but...

I thought there was no limit on how much energy you can have in a single point, didn't the universe start from a singularity, aren't black holes singularities too?

I know there was a proton detected once that had the energy of a baseball moving at 55mph i believe but protons have mass you can accelerate them indefinitely and you'd be increasing the energy of it (you can't do that to a photon). My question really involves much higher energies, like a photon...

Is there a limit on how much energy a single photon can carry? What is the most ever observed (detected(measured))?

I have a quick question, if an object is moving straight towards say Earth, isn't the gravitational field of Earth going to accelerate that object giving it extra energy? Where does that energy come from? Similar question, you have a hydrogen cloud in space, isn't the mass(energy) of that cloud...
