On the one hand, gravity hasn't been 'real' since Einstein: it's a secondary effect due to the curvature of space. On the other hand, gravity has been real since long before Newton: we experience it rather directly. The editorialized title gives the impression that there are entirely new insights concerning the 'reality' of gravity and that is certainly not the case.
- wlievens 16y ago"Scientist has hypothesized that gravity's origin may be somewhat different from previously considered, with no effect whatsoever on the real world" doesn't make for a very sensatinal headline.
- Confusion 16y agoThe original headline 'A Scientist Takes On Gravity' is good enough for the NYT and therefore good enough for HN.
- lurkinggrue 16y agoHe took on gravity... but did gravity win?
- alisey 16y agoGravity always wins.

To us it is enough that gravity does really exist, and acts according to the laws which we have explained." --Sir Isaac Newton's _Mathematical Principles of Natural Philosophy_
