Tiny ponderings about a very big universe.
Cosmic Questions takes the small puzzles of ordinary life seriously. Why does your own voice sound strange on a recording? Why does the moon look bigger near the horizon? Why is the way back always shorter? These are questions almost everyone has asked and almost nobody has looked up.
Each piece starts from one question and follows the research that tries to answer it — psychology, physiology, physics, perception. The answers are real: articles are written with the help of AI, checked against at least two independent sources, at least one of them published research, a university or an official body (or, when the question is about a word, an established dictionary), and those sources are listed at the end. Where science has not settled a question, the article says so plainly instead of pretending to a neat answer.
What makes these different from a quick search result is the patience. We explain the mechanism, show what the studies actually measured, and point out the common myths along the way. Some answers are surprising, some are gently funny, and a few end with an honest "nobody knows yet".
Three good first reads, picked by the editor.

Fact-based Cosmic Questions
That sudden certainty that you have lived this exact moment before is one of the strangest tricks a healthy brain plays, and psychologists have found a way to switch it on in the lab.
Fact-based Cosmic Questions
With your back turned you can usually tell a hot pour from a cold one, and the tidy explanation everybody repeats may have the whole thing the wrong way round.
Fact-based Cosmic Questions
Nine in ten of us get a tune stuck on repeat at least once a week, and researchers have worked out which songs do it, when they strike, and why a stick of gum can help.
Fact-based Cosmic Questions
Almost everyone gets hiccups, yet nobody is sure why the reflex exists, and the best clues come from unborn babies and tadpoles.
Fact-based Cosmic Questions
You learned to walk, talk and recognise your family in your first years of life, and yet you cannot recall a single moment of it, which is a very strange thing for a brain to do.
Fact-based Cosmic Questions
One enthusiastic spoonful too many and a sharp ache shoots into your forehead, and it turns out the pain has more to do with warm blood rushing in than with anything freezing.
Fact-based Cosmic Questions
That loud growl in a silent room is not really your stomach complaining about lunch, but your gut running a cleaning cycle through pipes that happen to be empty and echoey.
