Yesterday’s confirmation that gravitational waves exist is one of the greatest half-dozen scientific events of the last 100 years. Strangely enough, although gravity seems a strong unavoidable force in our daily lives — as I learned a few weeks ago when breaking a hip — it is millions of times weaker than electrical forces. The latter, in turn, are millions of times weaker than the nuclear forces inside the atom. Relatively weak though gravity is, it is hugely important and the galaxies and solar system couldn’t exist without it.
Even so, and even though no immediate applications have been spoken of — at least to my knowledge — knowing a bit more about gravity will start to weave a better understanding of the still largely mysterious world around us. So we’ll say to the scientists involved “Well done ! Continue to enjoy your work.”
