Asking Quote by Lawrence M. Krauss
““Whenever one asks “Why?” in science, one actually means “How?”. “Why?” is not really a sensible question in science because it usually implies purpose and, as anyone who has been the parent of a small child knows, one can keep on asking “Why?” forever, no matter what the answer to the previous question. Ultimately, the only way to end the conversation seems to be to say “Because!””

A Different Perspective
Overemphasis on “why” can stall discovery.
![“[I]n science we have to be particularly cautious about 'why' questions. When we ask, 'Why?' we usually mean 'How?' If we can answer the latter, that generally suffices for our purposes. For example, we might ask: 'Why is the Earth 93 million miles from the Sun?' but what we really probably mean…” quote by Lawrence M.
