Photons are their own antiparticles, actually.

If you and your ship had no mass in this universe you could go as fast as you want..."C" would be meaningless. Without mass you would not have to worry about running into solid matter stars planets etc, you and your ship would pass right through them just like a nutrino.

I'm probably not being original, But at what point would it be impossible to accelerate an object any more in reality( not on paper)
Never. You can keep accellerating and getting closer to C.
In practical terms, from the point of view of a stationary observer, there isn't much point as you get past 90% or so. From the point of view of earth, a probe launched a 0.9C toward a star 100 light years away will arrive in 111 years, one moving at 0.99C will get there in 101 years, and one moving at 0.99999C will get there in just over 100 years (not much difference between 101 and 100).
But from the point of view of someone riding the probe, it's a huge difference. Most of the additional energy put in to accelleration ends up increasing your time dilation. On the ship, a 100 light year trip at 0.9C takes 48.5 years. At 0.99C it takes 14.25 years, and at 0.99999C it takes just over 5 months.
Costs a LOT of energy, though. With the best current technology, we'd be lucky to achieve 0.01C.

The universe is expanding, but in order for the expansion to be significant two objects have to be many millions of light years apart. On smaller scales, the expansion is so tiny and slow that it gets overwhelmed by local forces like gravity and electro-magnetism.
A while back I think we ran through the calculation that at the orbit of Pluto, our solar system expands by a fraction of a millimeter per year. But the sun's gravity is more than capable of pulling Pluto back in by that much per year, so Pluto stays put.
But between us and another galaxy a few billion light years away, the expansion increases to a measureable fraction of C, and gravity fades by distance squared so it has dropped to insignificance. In that case, the expansion carries the galaxies away from each other.

In that analogy, the baseball in your hand already has a forward speed of 100mph. When you throw it forward, it will travel at 100mph relative to the train, or 200mph relative to a fixed point on the ground that the train is passing.
I am on a train's flatcar being pulled at 100mph..if I throw a baseball at 100mph in the direction the train is moving, will the baseball go anywhere or fall straight down?
