Cosmology & Universe

01

Big Bang Expansion

Watch the universe expand from its hot, dense initial state through cosmic epochs

02

CMB Anisotropies

Cosmic Microwave Background temperature fluctuations that seeded structure

03

Hubble Expansion

Galaxies recede with velocity proportional to distance: v = H₀ × d

04

Cosmic Redshift

Light wavelengths stretch as space expands, shifting from blue toward red

05

Dark Energy

The mysterious force driving the accelerating expansion of the universe

06

Cosmic Inflation

Exponential expansion in the first 10⁻³² seconds by factor of 10²⁶

07

Structure Formation

Density perturbations grow through gravitational instability

08

Baryon Acoustic Oscillations

Sound waves in early plasma left imprints on galaxy distribution

09

Gravitational Waves

Ripples in spacetime from accelerating massive objects

10

Cosmic Web

Galaxy clusters connected by filaments, surrounding vast voids

11

Type Ia Supernova

Standard candles that revealed the accelerating expansion

12

Quasar Luminosity

Supermassive black holes outshining entire galaxies

13

Gravitational Lensing

Massive objects bend light, creating arcs and Einstein rings

14

Primordial Nucleosynthesis

Formation of hydrogen, helium, and lithium in the first 3 minutes

15

Cosmic Reionization

First stars ionized neutral hydrogen, ending the Dark Ages

16

Cosmic Horizon

The observable universe and the particle horizon limit

17

Multiverse Bubbles

Eternal inflation and universe nucleation theory

18

Dark Matter Distribution

The invisible scaffolding where galaxies form

19

Cosmic Timeline

Journey through 13.8 billion years of cosmic history

20

Fate of the Universe

Heat Death, Big Crunch, Big Rip, or Big Freeze?
