In 2.3 billion years it will be too hot for life to exist on Earth Over the coming hundreds of millions of years, the Sun will continue to get progressively brighter and hotter. In just over 2 billion years, temperatures will be high enough to evaporate our oceans, making life on Earth impossible. Our planet will become a… Continue reading In 2.3 billion years it will be too hot for life to exist on Earth

Chalk is made from trillions of microscopic plankton fossils
Chalk is made from trillions of microscopic plankton fossils Tiny single-celled algae called coccolithophores have lived in Earth’s oceans for 200 million years. Unlike any other marine plant, they surround themselves with minuscule plates of calcite (coccoliths). Just under 100 million years ago, conditions were just right for coccolithophores to accumulate in a thick layer coating ocean… Continue reading Chalk is made from trillions of microscopic plankton fossils
Hawaii moves 7.5cm closer to Alaska every year
Hawaii moves 7.5cm closer to Alaska every year The Earth’s crust is split into gigantic pieces called tectonic plates. These plates are in constant motion, propelled by currents in the Earth’s upper mantle. Hot, less-dense rock rises before cooling and sinking, giving rise to circular convection currents which act like giant conveyor belts, slowly shifting the tectonic plates… Continue reading Hawaii moves 7.5cm closer to Alaska every year
A teaspoonful of neutron star would weigh 6 billion tons
A teaspoonful of neutron star would weigh 6 billion tons A neutron star is the remnants of a massive star that has run out of fuel. The dying star explodes in a supernova while its core collapses in on itself due to gravity, forming a super-dense neutron star. Astronomers measure the mind-bogglingly large masses of stars or galaxies… Continue reading A teaspoonful of neutron star would weigh 6 billion tons
The Eiffel Tower can grow up to 15 centimeters taller during summer.
This is because of “thermal expansion.” When an object is heated, its particles gain kinetic energy, move faster, and take up more space.
Some metals are so reactive that they explode on contact with water
The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table – they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen.
Babies have more bones than adults.
Babies have more bones than adults.An adult has 206 bones, but a newborn baby has nearly 300 bones in her body. This is because babies have more flexible cartilage (a firm tissue softer than bone) in the body. As the child grows, some of the cartilage hardens and turns to bone, and some bones fuse together.
