In today's world, science is so advanced that anything is possible through science, but there are still few things that science can't explain, such as:
- Why the universe exists?
We all know that the universe exists because of the big bang or other reasons, but scientists are still not sure why the universe exists. Many theoretical frameworks explain 'WHY', but scientists cannot conclude.
- Why do people yawn?
Yawning is something we likely do every day, but it's strange enough that scientists still aren't sure why. The scientific community has moved to the idea that yawning is a thermoregulatory behavior that calms down the brain, but its actual biological purpose is still unclear. A study published in 2005 by Cognitive Brain Research found that the networks in the human brain are responsible for compassion, and social skills are activated when we see someone yawn.
- Why Saturn's north pole has a hexagon-shaped swirling storm?
At Saturn's north pole, there is a hexagon-shaped weather system at the size of 2 Earths. The storm was observed and photographed by NASA's Cassini Probe; the reason behind the hexagon-shaped storm remains mysterious. The storm appears to have changed color from turquoise to yellow in just a few years, which makes the matter more confusing.
- Why do cats purr?
Scientists understand how cats purr, but why do cats Purr is still a mystery. As per BBC, it is usually thought that the muscles around the feline larynx of the cats constrict, which creates a vibration that makes the purring sound. A theory is that purring supports bone growth as the vibration frequency leads bones to harden in response to the pressure. But the reason cats purr is still a debatable question.
- Why there is dark matter or dark energy
A matter is made of protons, neutrons, & electrons, but what is dark matter is made of is still a mystery. Around 27% of the matter and energy observed by the universe is considered dark.
Since the beginning, the universe has constantly been expanding, but now, the expansion rate is accelerating outwards, and scientists are not sure where this energy is coming from. There are many models, theories, and extensive research going on about this, but none are conclusive.
