Black Hole Emits a 1,000-Light-Year-Wide Gas Bubble
PhrostyMcByte writes "12 million light-years away, in the outer spiral of galaxy NGC 7793, a bubble of hot gas approximately 1,000 light-years in diameter can be found shooting out of a black hole — one of the most powerful jets of energy ever seen. (Abstract available at Nature.) The bubble has been growing for approximately 200,000 years, and is expanding at around 1,000,000 kilometers per hour."
"The casual-conversation concept of "theory" as an plausible but unverified idea about the world is what in science would be a conjecture or a hypothesis, not a theory."
This is oft repeated garbage. Worse is the saying that a theory is essentially a scientific fact. A theory is no more a hypothesis which has withstood testing. All theories remain best guesses consistent with the observations seen to date and completely disposable tomorrow. In fact, there have been many theories which HAVE been tossed out in favor of new theories. In fact, there are multiple conflicting theories in many areas.
Acting as if theories are somehow more than the current best guess(es) of the scientific method is throwing out the skepticism that is the core of said method. It simply isn't worth throwing out science for the sake of dismissing the flippant "it's just a theory" remarks.
And don't bother with "technically that's true but..." technically that's true invalidates the but you'd be tempted to tack on the end. Period.
Here's a hint: if you call yourself a guru (as your nickname would imply) and come into a forum correcting people, using large words doesn't help your case. Especially if you use them wrong. The term you are looking for is the more common "wording." Phraseology is the study of multi-word colloquialisms.
