I've never heard of this probe to the sun. They know very well a probe wouldn't survive, so that would be a suicide mission, when they could get just as close by putting it in orbit, and they'd get much more information. I'm not saying they didn't send a probe, but it seems unlikely that they'd do that and claim the information about the interior of the star came from that probe. BTW, they theorize that each photon we see starts in the core of the sun as a gamma ray, a byproduct of nuclear fusion, then bounces around in the core for up to 100,000 years, where it loses energy each time it bounces off or gets absorbed and emitted by hydrogen, helium, etc. atoms, eventually becoming an x-ray, then visible light before finding its way to the corona and making its 8 minute trip to Earth. They theorize this based on mathematics and quantum mechanics. Are they right? I don't know, but I give them 85% of my trust that they know what they're talking about.
As for wormholes, they've never claimed they exist, only that if space is curved, it's possible that wormholes could exist as shortcuts between 2 points in space.
Here is the scientific definition of theory:
In everyday use, the word "theory" often means an untested hunch, or a guess without supporting evidence.
But for scientists, a theory has nearly the opposite meaning. A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts. The theory of gravitation, for instance, explains why apples fall from trees and astronauts float in space. Similarly, the theory of evolution explains why so many plants and animals—some very similar and some very different—exist on Earth now and in the past, as revealed by the fossil record.
A theory not only explains known facts; it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable. New evidence should be compatible with a theory. If it isn't, the theory is refined or rejected. The longer the central elements of a theory hold—the more observations it predicts, the more tests it passes, the more facts it explains—the stronger the theory.
