I wouldn't say the first one was is wrong, but when stating sentences of that nature it's more natural to use "less" than "later." However, the second sentence changes meaning completely if you use "less" rather than later".(1) "The North Pole was discovered later than a century ago."?Why is (1) wrong because the "later" mean a recent event, but (2) is correct?
(2) Mozart was born later than Bach.
