Light is effected by gravity. A black hole is basicly a giant gravity well and it sucks in light. Also if you observe light from distant stars is id pulled toward gravity pockets like a neutron star etc. The main reason we dont seel all stars is not that the light don't reach us but that when it does it has bled in with other stars what you might think is a single star is a galaxey or a golobular(sp) cluster. The distance is just so great it apperas as a single star not a million. Also light spreads out as it travels due to its duplex stats as a wave and a particle. As a result as it spreads it disapates, and in doing to becomes absorbed it objets it hits, be it a dust particle, a planet, comet, their is allot of stuff out their between us and the nearest start beyond the sun. But even the sun looks the size of a quarter and its many many times the size of the earth.
