Research and summarize the Big Bang, Steady State, Pulsating Universe, and Inflationary theories of the universe's origin.

You need to find information online about the following four theories:

• Big Bang Theory
• Steady State Theory (Estado Estacionario)
• Pulsating Universe Theory (Universo Pulsante)
• Inflationary Theory (Teoría Inflacionaria) Use reliable sources like NASA, other space agencies, scientific publications, or digital books.

Read at least two different sources for each theory. Do not copy directly; instead, write the information in your own words.

Prepare a handwritten summary in your Science notebook. It must be at least half a page long and include:

• A clear explanation for each of the four theories.
• For each theory, state what it proposes, who proposed it, and approximately when it emerged.
• Include "Vínculos" (links/connections) between the theories where appropriate.

At the end of your summary, list the titles of the websites or sources you consulted.

Ensure your summary is presented neatly in your Science notebook with good handwriting. The assignment is worth 4% of your grade and is due on Monday, May 4, 2026.
