Mind-blowing science facts
A bolt of lightning reaches temperatures of about 30,000 Kelvin — five times hotter than the surface of the Sun.
If you typed out all the DNA instructions in your body, it would fill 600,000 pages of printed text.
According to Einstein's theory of general relativity, gravity can bend light. Massive objects like stars curve the space around them, causing light to follow a curved path.
Archaeologists have found 3,000-year-old honey in Egyptian tombs that was still perfectly edible, because honey's low moisture and high acidity prevent bacteria from growing.
A single bolt of lightning contains about one billion joules of energy — enough to power a 100-watt light bulb for over three months.
DNA is shaped like a twisted ladder called a double helix. Each rung of the ladder is made of pairs of chemical bases that carry genetic instructions.
Every magnet has a north pole and a south pole. If you break a magnet in half, each piece still has both a north and a south pole.
Through photosynthesis, plants use sunlight, water, and carbon dioxide to make their own food — and release oxygen as a byproduct that we breathe.
Black holes are invisible because their gravity is so powerful that not even light can escape. Scientists detect them by observing how they affect nearby matter.
About 90% of an iceberg sits beneath the surface of the water because ice is only slightly less dense than liquid water.
