🥇 Expert

Big Bang

The origin of the universe approximately 13.8 billion years ago from an extremely hot dense state

Example

Tyson explains how the Big Bang created space time and matter in an instant of cosmic creation

Dark Matter

Invisible matter that does not emit light but exerts gravitational influence on visible matter

Example

Dark matter makes up about 27% of the universe but cannot be directly observed

Dark Energy

The mysterious force causing the accelerating expansion of the universe

Example

Dark energy comprises about 68% of the universe and pushes space apart at increasing rates

Cosmic Microwave Background

The faint radiation left over from the early universe visible in all directions

Example

The CMB is the afterglow of the Big Bang providing a snapshot of the early universe

Light Year

The distance light travels in one year approximately 5.88 trillion miles

Example

Light years help express the vast distances between stars and galaxies in comprehensible terms

Electromagnetic Spectrum

The full range of electromagnetic radiation from radio waves to gamma rays

Example

Most of what we know about the universe comes from observing different parts of the electromagnetic spectrum

Exoplanet

A planet orbiting a star other than our Sun

Example

Thousands of exoplanets have been discovered some in potentially habitable zones

Periodic Table

The organized arrangement of chemical elements that originated in stars

Example

Elements heavier than hydrogen and helium were forged in stars making us literally star stuff

Gravity

The fundamental force of attraction between masses that shapes the cosmos

Example

Gravity governs the motion of planets stars and galaxies across the universe

Neutron Star

The ultra-dense collapsed core of a massive star composed almost entirely of neutrons

Example

A teaspoon of neutron star material would weigh billions of tons on Earth

Black Hole

A region where gravity is so strong that nothing including light can escape

Example

Black holes form when massive stars collapse and warp spacetime to extreme degrees

Cosmic Perspective

The worldview that comes from understanding our place in the vast universe

Example

The cosmic perspective provides humility and wonder about our existence in the cosmos
