Here are some general facts about science

the journey never ends!

"Who looks outside, dreams; who looks inside, awakes"- Carl Jung

Energy can neither be created nor destroyed; it only changes form (First Law of Thermodynamics).
Matter is made up of atoms, which are composed of protons, neutrons, and electrons.
Gravity is the force of attraction between two masses.
Light behaves both as a wave and a particle (wave-particle duality).
Sound travels faster in water than in air.
The unit of force in the International System of Units is the newton (N).
Absolute zero (-273.15°C or 0 Kelvin) is the lowest possible temperature, where particles have minimal motion.
The speed of light in a vacuum is approximately 299,792 kilometers per second.
Electricity is the flow of electrons through a conductor.
The Doppler effect explains the change in frequency or wavelength of a wave in relation to an observer moving relative to the source.

Water is a universal solvent because it can dissolve many substances.
The periodic table organizes elements by increasing atomic number.
Atoms bond together to form molecules.
Carbon is the backbone of all organic compounds.
Table salt is made of sodium and chlorine atoms (NaCl).
A pH scale measures the acidity or alkalinity of a solution, ranging from 0 to 14.
Diamond and graphite are both forms of carbon but have different structures (allotropes).
Combustion is a chemical reaction that typically produces heat and light.
Noble gases, like helium and neon, are inert because they have complete outer electron shells.
Enzymes act as catalysts in biological reactions.

The Sun is a medium-sized star located in the Milky Way galaxy.
A light-year is the distance light travels in one year, about 9.46 trillion kilometers.
There are eight planets in our solar system.
The Moon’s gravity causes tides on Earth.
Black holes form from the collapse of massive stars.
The asteroid belt lies between Mars and Jupiter.
Venus is the hottest planet in our solar system due to its thick atmosphere of carbon dioxide.
A day on Mars is roughly 24.6 hours long.
The Milky Way galaxy is a barred spiral galaxy.
Space is a vacuum, meaning it has no air or other gases.

The Earth's core is made primarily of iron and nickel.
The crust is the outermost layer of the Earth.
Plate tectonics explains the movement of the Earth's lithospheric plates.
Volcanoes form when magma from the mantle reaches the Earth's surface.
The water cycle includes evaporation, condensation, precipitation, and runoff.
The Earth's magnetic field is generated by the motion of liquid iron in its outer core.
Fossils provide evidence of ancient life on Earth.
Earthquakes occur due to the release of energy along fault lines.
The ozone layer protects the Earth from harmful ultraviolet radiation.
The Pacific Ocean is the largest ocean on Earth.

Atoms are mostly empty space.
Energy from the Sun is created through nuclear fusion.
The scientific method involves observation, hypothesis, experimentation, and conclusion.
Evolution explains the diversity of life on Earth.
A species is a group of organisms capable of interbreeding and producing fertile offspring.
Vaccines help the immune system fight diseases.
Carbon dioxide is a major greenhouse gas contributing to global warming.
Natural selection is a key mechanism of evolution.
Antibiotic resistance occurs when bacteria adapt to survive antibiotics.
Renewable energy sources include solar, wind, and hydropower.

X-rays are a form of electromagnetic radiation used in medical imaging.
GPS relies on satellites to provide location information.
Robots can perform tasks autonomously or semi-autonomously.
The first artificial satellite, Sputnik 1, was launched in 1957.
Drones are used in agriculture, delivery, and surveillance.
Nuclear energy is generated by splitting atoms in a process called fission.
Prosthetics help people regain mobility or functionality.
The Large Hadron Collider (LHC) is the world's largest particle accelerator.
3D printing allows the creation of objects layer by layer from digital designs.
Artificial intelligence is used in fields such as healthcare, finance, and transportation.

The human body can produce about 25,000 quarts of saliva in a lifetime.
Spiders are arachnids, not insects.
Sharks existed before dinosaurs.
The giant panda's diet is 99% bamboo.
Lightning is hotter than the surface of the Sun.
Earth's orbit is elliptical, not circular.
Saturn's rings are composed mostly of ice and rock particles.
The International Space Station orbits Earth at about 28,000 kilometers per hour.
Caffeine is a natural stimulant found in coffee and tea.
Bats are the only mammals capable of sustained flight.
