Is my thinking of the concept of lightyears correct?

So light years is how long it takes for light to reach a place (which considering how fast light is even one light year is a huge amount by our standards) So does this mean it’s technically possible to look at the past? If we somehow made it somewhere 2000 light years away and built a powerful enough telescope... show more So light years is how long it takes for light to reach a place (which considering how fast light is even one light year is a huge amount by our standards)
