Everyone who's just curious about science - up to the top expert on nuclear fusion - will find something here! Hundreds of the most interesting science questions are answered and are split into 3 categories: Light, Physics and Sound.
What weird and cool effects occur when two gigantic mirrors face each other?
What happens to water if you compress it more and more and more... (It can't just disappear)?
What's the temperature of a candle flame?
What on earth would liquid diamond or gold taste like if it was cool enough to drink?
Can liquid diamond be made and if so, what temperature would be needed?
All of these questions and hundreds more will be answered!
Gradually, week by week, more and more questions are being
answered so if you have any of the missing answers
to some of the questions, visit Skytopia's
Whirlpool of Knowledge Forum. Also, if there's
an answer you can clarify further, or add to in some
way (anecdotes are very welcome), then don't hesitate to contact me.
All feedback appreciated!
