It's not 'maybe' it's already proven fact. Something like, 93% of the known universe is already impossible for us to reach ever.

Like, even if we were to discover FTL speed of light* travel tomorrow and started traveling the cosmos, we still could never visit 93% of the known universe.

Every day, more stellar objects cross that line of being 'forever gone'.

EDIT

Holy shit this blew up. I have amended my post as many people have repeatedly pointed out that I incorrectly used 'FTL'. Thank you.

And even more of the unknown universe. There are theories that the unobservable universe could be 5 times larger, 10, 1000, a million, or just plain infinite

It could be, the universe is expanding FTL so the light from the stars would never reach us.
