7.5 Evidence Supports the Big Bang Theory

From a tiny, hot, dense state that has been expanding ever since

From a massive explosion in space

From the collision of two galaxies

From a cold, empty void

Their light is red-shifted, meaning they are moving away from us

They are getting brighter over time

They are shrinking in size

They are colliding with each other

Red-shift of galaxies

Cosmic Microwave Background Radiation (CMBR)

Elemental mix of hydrogen and helium

Presence of black holes

They map tiny temperature changes in the CMBR, confirming the Big Bang model.

They measure the speed of light in space.

They detect gravitational waves from black holes.

They observe the formation of new stars.

Using telescopes to measure red-shift and study galaxy movement.

Using satellites to map the CMBR's temperature patterns.

Using microscopes to study atoms in space.

Using submarines to explore the ocean floor.

The stretching of light wavelengths from distant galaxies, indicating they are moving away from us.

The shrinking of light wavelengths from nearby stars.

The increase in brightness of a star as it approaches Earth.

The sudden appearance of new galaxies in the sky.

Red-shift of distant galaxies

Mapping of CMBR temperature changes by satellites

The steady state of the universe

Faint signals or radiation left over from the early universe

The sound of galaxies colliding

The light from the nearest stars

The gravitational pull of black holes
