If one were to be right at the outmost region of the expanding universe, and accelerate with it, would all matter look like a singularity, one infinately small dot of matter/energy? or is there an even distribution of new energy and matter being formed while the universe expands?

NONE OF THE ABOVE...

If one were at the at the outermost region of the universe, which is a totally unknown place at this time and farther than 40 Billion Light Years away, what one would probably see is a wide spectrum of lights emitted by the tens of thousands of galaxies across the entire spectrum of his vision. It would be entirely impossible to see one tiny pinpoint of light out there in the middle of all of everything.

New matter is not being "formed" anywhere. It is being collected up from all of the previous collisions and explosions in the far distant past which scattered it widely across space. As it is collected up, and depending upon what it is and how much of it is collected, different things mighjt be formed. Massive bubbles of gases form into future stars for example. Rock, metals, and silica materials form into asteroids, moons, and even planets. So, the forming is not "creation", it is just the gathering up of existing scattered debris, much like gathering up snow to make a snow ball.

I have to agree with Zahbudar. If you were, by some bizarre means, able to travel to the outermost portions of space, far enough to beat the waves of radiation, you might just be able to turn around and witness a cosmos in its birth. Not that you would be able to see it, of course, but you would probably be able to "see" it as a rapid and explosive expansion of radiation.

However, if you want to really think about it, providing that you had the transportation to go as far as beating the waves of radiation from the singularity . . . where, and when, would you exactly be? If the universe is the result of this singularity, and all matter (dark and light) was contained in this singularity before the singularity went nuclear . . . then wouldn't you be nowhere and, more precisely, outside the limits of time? This would render your existence a paradox and you would never be able to witness the event because your very being wouldn't exist. Just a thought.
