I disagree. Carbon-14 dating is totally unreliable.

I don't think anybody has proved that.

The mysterious substance known as dark energy thought to be pushing the universe apart at ever greater speeds may be nothing more than an artefact of our acceleration through a local patch of the universe. That is the controversial claim of a group of physicists who reckon they have found flaws in the evidence underpinning the Nobel-prize winning discovery of cosmic acceleration. The dispute centres on exploded stars known as type Ia supernovae, which allow researchers to calculate cosmic distances and rates of expansion.

Type Ia supernovae are known as “standard candles” since they are generated by stars exploding with a very specific mass and therefore known absolute brightness. By observing these objects’ apparent brightness, astronomers can work out how far they are (in space and therefore time), and by combining that information with the red shift in their emitted light can then calculate how fast the universe was expanding at that point in time.

Question: Is exploding a present participle or a gerund?

It looks like a present participle to me.

Topic: What does "two distinct visitors" mean?

Distinct is not the right word, I think they mean different - . ie no more than two individuals.
The same person can visit many times, and only counts as one visitor.

Topic: unexplained anxiety attacks

the term 'anxiety attack' is a known compound noun. Like a 'heart attack'. So these are anxiety attacks that are unexplained. Ie you don't know why you are having an anxiety attack.

it is not an attack of unexplained anxiety, because an attack of anxiety is different from an 'anxiety attack', which is a specific set of symptoms.

So although grammatically you might read it as attack of unexpected anxiety, where 'unexplained' modifies 'anxiety' it is actually like an "unexpected heart attack". It is the attack that is unexpected, not the heart!

In this case it actually produces a similar result of meaning, because the anxiety comes on unexpectedly. What is specific to that meaning though is that it causes a specific 'anxiety attack' with a specific set of symptoms.

If I suddenly get worried about something, I might have an attack of anxiety. I am worried, distracted, anxious.

I have trouble breathing, racing heart, chest pain, feel I am going to pass out - that is an anxiety attack. (not within my personal knowledge, but you get the point). That can be expected sometimes. If a person scared of small spaces is trapped in a lift, it is expected that they might have an anxiety attack. That is not neurosis. But if the fears are generated more randomly, then the attacks might be unexpected. That is neurosis.

My explanation veered rather more into medicine than I had intended, and I really know nothing about this area of medicine, so I might have got major points wrong there.
But in answering your question, that part I am confident about.

I concur!....Nice explanation!...
