Nature of Dark Matter – travelling faster than light

I have been working on the maths and the theory for several months now in order to discover the nature of dark matter. By rearranging and solving the Friedmann equations I have found the mass of dark matter to be half the energy-mass equivalent of a single photon – therefore it can be said dark matter has half the mass of a photon. Yes, it is true that photons do not have a rest mass. My comment is regarding the mass equivalent of a photon. Energy of a photon is found using E=hf, whereas matter is found using E=mc^2. If we equate the two equations, we can find the equivalent mass a photon has if it were to have a mass. Using this value, the Friedmann equations and then comparing the two, I have found the mass of dark matter to be half the value of the mass equivalent of a photon.

Now, imagine dark matter has the same energy as a photon but half the mass – it can therefore travel faster than the speed of light. As we know, travelling at or near the speed of light, increases mass. Due to travelling faster than light, dark matter has a higher than usual mass and thus accounting for the large ‘missing’ mass around galaxies.


This is the reason why light cannot interact with dark matter; it is essentially too fast for light to interact with it. Even when something is dark, when hit by light, baryonic matter will become luminous. Dark matter is therefore non-baryonic, travelling faster than light and has a mass half that of a photon.

Due to dark matter only interacting with other forms of matter via gravity, the kinetic energy it possess does not dissipate to the surroundings. I am suggesting that, like light, dark matter has a fixed speed, so although its speed is greater than that of light, its mass is not constantly increasing.

I wouldn’t use the word ‘invisible’. What my theory suggests is that because dark matter travels faster than light we cannot directly observe it using light. It would be like trying to run after Usain Bolt to pin a badge on him. Never going to catch him so the badge never gets stuck to him. The light cannot bounce off the dark matter and back into our detectors because dark matter is moving so fast. If dark matter travelled at speeds slower than light, we should be able to observe something (that is in great abundance compared to normal baryonic matter) other than through its effects on spacetime.

“But nothing can travel at or faster than light!!!” But yes, it can!

This is more true for objects that are being accelerated. Relativity states that no object can be accelerated to the speed of light or greater, but it does not rule out the possibility of something existing and constantly travelling at speeds greater than light.
If we were to accelerate a clock to the speed of light it would slow down and eventually stop. If it were to accelerate over the speed of light it is possible that time could reverse, but this is just speculation because we don’t actually know if time travel is possible. But, if something, such as dark matter, were to exist and be constantly moving at speeds greater than light this law does not apply because it has not been accelerated – it already exists at this speed.

 
How was it made?

So, how was it created? I theorise that dark matter was created from the energy before the Big Bang and because it only interacts via gravity this energy does not dissipate to the surroundings, allowing it to travel faster than light indefinitely. Although my theory does not yet cover this next point, I believe it is worth a mention: Dark matter can also be created and released from black holes. Inside black holes we could have the right conditions to create dark matter and due to dark matter travelling faster than light can escape the gravity of a black hole, this is known as Hawking radiation.

It could be responsible for causing the Big Bang, its gravity pulling things closer together – but that is not part of my theory, more just a suggestion. Due to dark matter being present in the first instances after the Big Bang, it is responsible the clumps of matter indicated by the COBE satellite. If this was not the case and dark matter is being created, we would probably find a more even spread of matter. 

Whilst I did state that it could be possible for dark matter to be created in black holes as it could provide the right conditions (dense and energetic) for dark matter to be created, it is more of a hypothesis at the current stage. However, dark matter is spread throughout galaxies, in addition to the halos of dark matter, and this could be due to dark matter being created at the centre. This has been shown by the work of Peebles and Ostricker in the 1970s.
