Scientific 'facts' are often proved wrong

I was amused reading the letter from "Beagle", in which he approvingly quotes someone as saying, "The good thing about science is that it is true ... " (Write Back, November 29). Does he not know how often science has had to change its mind over the years in what it called "truth"?

For example, for generations scientists believed the universe had always existed without any beginning. When the Big Bang theory was first posited, many scientists refused to believe it. Yet now it is considered "true" - unless, of course, some other theory replaces the present "truth" in future.

And Richard Dawkins some years ago proclaimed that there were bits of DNA in the human body which were leftovers from evolution and were of no use whatsoever.

Since then, scientists have discovered that, far from being useless, they were extremely important. So, once again, "truth" was found to be wrong.
