Verified wonders from the science desk.

Can lightning get hotter than the Sun's surface?
Yes. NOAA explains that lightning can heat nearby air to around 50,000 degrees Fahrenheit.
Is most of the ocean still unmapped in high detail?
Yes. NOAA repeatedly notes that the ocean is still only partly explored and mapped.
