This is because we know that the universe isn't infinitely old - we know that the big bang occured some 13.8 billion years ago. So from this we can conclude that the light has had only 13.8 billion years to travel and hence defines the limitations of universe. All we know or scientists believe is that universe is still far above  from our observable distance but at some point it has limits for sure.

Although it looks possible  scientifically and factually bout still practically it has been mentioned as not possible and has been included in "pseudoscience". I hope a interest is been developed in your brai...
