Picture is cosmic dust in Andromeda galaxy, as you can see dust is not that rare in space.

Now you just consumed the energy of an entire star to accelerate your ship to near the speed of light. What do you think will happen when you hit cosmic dust? Nuclear fusion! And you will also need to break from that speed and for that you will need the energy from another entire star for that.

Scientists only use intergalactic travel to get people interested in science.
