I have trouble understanding two lines in an article in NYTimes.
Ever more so, it seems. The past few decades have seen “an amazing array of experimental tests of general relativity, all of them in agreement with the predictions,” Dr. Will said. But the quest continues: “There are still things we don’t fully understand. And that’s probably likely always to be the case.”
Here does the last line mean that it's very likely that scientists will always find something that they don't fully understand?
“The more we keep testing it, the more confidence we have in the theory,” he said. “And of course on the other hand, any sort of deviations from his predictions would surely tell us that there is something new to be investigated.”
Here does the highlighted line means that any deviation from Einstein's predictions would make the scientists doubt themselves?
