Does "take on Einstein" mean "challenge Einstein"?
Context:
Astrophile: Trio of dead stars could take on Einstein
Objects: A fast-pulsing star and two white dwarfs Location: A rare triple-star system The three friends had been through a lot over the years. One had an explosive personality that in the early days nearly drove the friends apart, but has since settled down to ticking away the time. The two others have a complicated relationship with the clock-watcher, one preferring to stick close by, while the other keeps its distance. Together, the trio are attempting to put Einstein to the test. http://www.newscientist.com/article/dn24813-astrophile-trio-of-dead-stars-could-take-on-einstein.html
