What's happening up there? Any theories?
What precisely is your point Vid?
Allow me to expand a bit, as I've formulated my point rather short and clumsily:
By «What's happening up there?» I mean 'What is happening up there?'. Or with some added context: 'What do you people who frequent this forum believe may be happening up there?'.
Now, to the next sentence, I believe equally incomprehensible: «Any theories?». By that little enigma, I intend to request people who frequent this forum as to whether they have any ideas — not 'theories', strictly scientifically speaking — as to what may be 'happening up there' (see further explanation above).
In summary, I can see why you are confused. I should formulate more complete sentences where I also include some context to the questions. I should perhaps also explain that I would like people to answer said questions, they are not posed as 'statements' or any such thing, they are, in fact, questions, posed to the larger community, in hope of knowledgable answers.
