Who proposed the steady-state theory?

Fred Hoyle, Herman Bondi, and Thomas Gold proposed the steady-state theory in 1948. Signup and view all the answers

What is the difference in the appearance of the universe according to the Big Bang theory and the Steady State theory?

Both theory models depict an expanding universe. The Big Bang theory posits an expansion where the matter in the universe dilutes, with no new matter being created. The Steady State theory depicts an expansion where new matter is constantly created with a fixed average density. Signup and view all the answers

How did Edwin Hubble's discovery of redshift support the Big Bang theory?

Edwin Hubble observed that galaxies are moving away from each other, as evidenced by the redshift of light that is observed in the spectrum. This supported the Big Bang theory because it indicated that the universe is expanding from a single point, which aligns with the Big Bang model. Signup and view all the answers

Describe the evolution of the universe after the Big Bang, according to the Big Bang theory.

After the Big Bang, the universe transitioned from a hot, dense state to a cooler period where atoms, stars, and galaxies were formed. The universe continues to expand today. Signup and view all the answers

Study Notes

Earth and Life Science: Universe Origin

The objectives of the lesson include describing the universe's structure and composition, explaining redshift as proof of an expanding universe, and explaining the Big Bang Theory and its supporting evidence.
Creation myths are symbolic narratives explaining the world's beginning from various cultures' perspectives.
- Ancient Egyptians believed the world arose from an infinite sea at the sun's first rising.
- The Kuba people's myth features a creator god, Mbombo, who vomited cosmic elements.
- Indian narratives describe the primal man Purusha's sacrifice creating the cosmos (sky, earth, sun, moon).
- Monotheistic religions (Judaism, Christianity, Islam) attribute universe creation to a supreme being.
Genesis, a book in the Hebrew Bible and Christian Old Testament, details the cosmos's creation in six days.
Genesis 1:17 (NIV) describes God placing light sources in the sky to illuminate Earth.
The Big Bang Theory posits that the universe originated from a singularity 13.8 billion years ago.
- Proponents of this theory include Alexander Friedmann and Georges Lemaître (1920).
- There was nothing in nothingness that, due to a random fluctuation, expanded greatly, in all directions. Space, time, energy, and matter began moving.
- The universe's expansion led to the formation of particles, elements, stars, and galaxies as time passed (from Planck era to the present).
The steady-state theory proposes that the universe expands but maintains constant density, continually creating new matter to balance the universe's expansion.
- This theory was proposed by Fred Hoyle, Herman Bondi, and Thomas Gold in 1948

Expanding Universe

In 1929, Edwin Hubble's discovery of redshift (light shifting to longer wavelengths) supported the concept of an expanding universe.
- Hubble observed starlight passing through a prism and noted the shift to lower frequency, implying galaxies move away from Earth.
- This observation aligns with Einstein's Theory of General Relativity.

Enrichment: Fate of the Universe

The current theoretical discussion focuses on whether the universe will continue expanding or contract due to gravity.

Activity: Comparing Cosmology Models

Students are to use a Venn diagram to highlight similarities and differences between the Big Bang and Steady-State models of the universe.

Universe Origins Concept Map

The concept map illustrates a breakdown of the universe's timeline, from origin (13.8 billion years ago) to factors influencing the formation of the solar system and other celestial bodies (4.6 billion years ago).
The map categorizes different cosmological theories, such as Big Bang, steady-state, and various other theories (Vortex, Collision, Tidal, Nebula, and Solar Nebula theory).
