I've often seen that "we can only look back in time a short distance in linguistics". What prevents linguistics from deducing information far in the past? Is this limit something that can be pushed...

Why is linguistics limited in how much it can look back in time?
I've often seen that ["we can only look back in time a short distance in linguistics"](https://linguistics.stackexchange.com/questions/315#comment602_315). What prevents linguistics from deducing information far in the past? Is this limit something that can be pushed back with development of the science of linguistics?
