If someone were on a spaceship traveling at a significant fraction of the speed of light, they would experience a phenomenon known as "stellar aberration." Stellar aberration causes the apparent position of stars to shift as a result of the observer's motion relative to the speed of light.
As the spaceship moves close to the speed of light, the light from stars in the direction of motion would appear to be compressed towards the front of the spaceship, while light from stars opposite to the direction of motion would appear to be shifted towards the rear of the spaceship.
This effect creates the illusion that stars are not only passing by the spaceship but also that there is a concentration of stars towards the front of the spacecraft and a dearth of stars behind it. However, it's essential to note that this effect is optical and does not imply that the stars are physically moving or that the spaceship is passing through the stars. The stars' positions in the sky are not changing; it's just their apparent positions due to the observer's motion.
Additionally, as the spaceship approaches the speed of light, the light from the stars in the forward direction becomes increasingly blue-shifted (shorter wavelengths), while the light from stars in the rearward direction becomes increasingly red-shifted (longer wavelengths). This is a result of the relativistic Doppler effect, which occurs when the observer and the light source are moving relative to each other at high speeds.
Overall, a person on a spaceship traveling at near light speed would experience visual distortions due to stellar aberration and relativistic Doppler effects, but they would not see stars passing by like objects passing by a car window. Instead, the stars would appear to be shifted and concentrated in certain directions, giving a unique and dynamic view of the universe as the spaceship moves.
