The page cannot be scrolled down beyond the point where the bottom of the page is at the bottom of the browser.
You don't add space to the bottom using <p> </p> though - you should add the space by increasing the bottom margin on an appropriate element in the page via the CSS. Doing it witl empty paragraphs could result in printing unnecessary blank pages when the page is printed and is providing content that says nothing where all you are trying to do is change the appearance.
If you wanted it to be temporary then you could have JavaScript in the destination page check the value in the location.hash field and dynamically apply the larger margin when required.
