What is a hidden fact in biology?

A surprising biological fact is that humans are ecosystems, with microbial cells (bacteria, fungi) roughly matching our own human cells, influencing digestion, immunity, and even mood by producing vast amounts of neurochemicals like serotonin, meaning we're deeply interconnected with our microbiome. Another is that our bodies glow with bioluminescence, but the light is too faint for human eyes to see, and that things like the bald eagle's iconic cry are often faked in media, actually belonging to the red-tailed hawk.

Why is 95% of the universe invisible?

About 95% of the universe is invisible because it's made of dark matter (around 27%) and dark energy (around 68%), which don't emit, reflect, or block light, unlike the ~5% of "normal" matter (stars, planets, us) that makes up everything we can see. We know these invisible components exist due to their gravitational effects, such as galaxies rotating too fast and the accelerating expansion of the universe, but their fundamental nature remains a mystery. 

How long is 1 minute in a black hole?

One minute for you near a black hole could be days, years, or even millennia for someone far away, depending on how close you are to the event horizon, due to extreme gravitational time dilation; time slows down dramatically as gravity intensifies, so your minute stretches out incredibly long for an outside observer. The closer you get to the point of no return (event horizon), the slower your time flows relative to distant observers, with time appearing to almost stop at the horizon itself.
