as it seems that the universe its expanding, and distant galaxies are constantly moving faster and faster away from us, this increase in speed its more noticeable in galaxies which are really far away from the milky way as the doppler effect sugests, so what is happening at the edge of the universe, are things moving apart relative to earth at faster then light speed? who can give me an insight into this question?

The furthest galaxies found are moving at 0.9c, if there were any galxiesmoving at or faster than the speed of light they would be undetectable because redshift would flatline any light from them.

Hello,
(ANS) OK!! Yes! this is a very complex question and I dont think your going to get any definitive (right or wrong!) answers to this one. Why? because any answer will remain in the relms of theory.
**As I understand the theory of the big bang, the universe was created from a singularity event which took place 200 billion years ago. From that instant (big bang) all time, matter, space & gravity started and all the matter in our universe started to expand outwards in all directions at the same time.
As objects within our universe travel away from us at the speed of light, its NOT the speed of the light itself that changes but the distance of the object and thus the distance the light has to travel to reach us (when we see the object).
Thus the further away the object "the older the light" is because its had to travel so far. NOTE: The speed of the light remains a constant value. So No! objects dont increase in speed as they move away from us. They just carry on moving away at the same constant speed, but as they move away we are seing them as older & older. The light from these objects or other galaxies is millions of years old, going back in time.
So to summerise this, objects we can still see at the edge of our observable universe through tools like radio telescopes or with the Hubble deep space telescope. We are looking at objects created millions & millions of years ago, obviously some objects have receeded so much that their light bearly registers with our instrutments because they are so far away & so ancient. Beyond these limits even scientists cannot say what takes place out in the primal void, its a pure mystery.

There is no edge of the universe. It don't sound right, I can't picture it but that the story. And things are't moving faster than speed of light. It could only be that space is expanding faster than light. this is all enougth to give me a headache

First of all... fantastic concept, I really like the question!
Second of all... I have no authority on the subject beyond Physics GCSE, so this conclusion is derived from conjecture and logical calculation rather than solid knowledge...
Third of all... my views
Nothing can move faster than light, so the most distant parts of the universe can only be moving at light-speed itself... if they were moving at light-speed away from us, we wouldn't be able to see them because the light coming towards us would be standing still. (theory of relativity)...
so yeah, they are going pretty damn fast, but no faster than light, and if they reached light-speed we would have no way of knowing...

Nothing can travel faster than the speed of light - it is a universal maximum speed beyond which matter cannot exist in the physical universe.

Speed is the rate at which something moves or travels. Expansion doesn't have speed, because different points in the universe move with different speed relative to each other. Instead, it's more correct to say "rate of expansion".

Nothing to our knowledge is faster than the speed of light.

it has got me thinking but none of these people know the anser to the question and if they have a theory take it with a pinch of salt .
humans cannot explain anything to do with the edge of the universe how can we?
it is beyond the relms of the science belonging to our planet
what is the universe expanding into?
even the cleverist human cannot explain infinity properly.
there is no explanation to the nothingness of beyond.
the question is beyond physical comprehension, no one actualy KNOWS anything it is all theory

Yes, we can only suppose that there is galaxies moving but since the universe has no edge, who know where they are going....

nothing moves faster than the speed of light. it doesn't happen, ever.
