Correct. We know, on a galactic scale, that we can be observing a star that is actually going supernova now, and we won't know it happened for many years.
On a micro scale, it just means our consciousness can never exist in, or register, the present state of the actual world.
Heisenberg noted the act of observation changes the nature of observed particles, but there's 2 things going on at the same time that make this true. You can think of the act of observation analogous to active sonar pinging, but if the pinging were instant, there would be no change observed in the particle, even though the particle is definitely altered. But... Because there's a time delay, it absolutely makes a difference between the observed state and the actual state of a particle, which makes true observation of the present state of a particle impossible.
