The Big Bang Theory is...
What is the theory that the universe began with a massive expansion about 13.8 billion years ago?
What does heliocentric mean?
It means that the Sun is at the center of the solar system.
Name the four inner planets of the solar system.

Evidence that supports the Big Bang Theory
What is the expansion of the universe or the increasing distance of the galaxies?
Who proposed the heliocentric model?
Nicolaus Copernicus
What is the largest planet in our solar system?
Jupiter
How has the Big Bang Theory changed over time?
It has evolved with new discoveries, like the inflation theory, which explains the rapid expansion of the universe. We know it's more of an expansion of space rather than an explosion.
What was the main idea of the geocentric model?
The Earth is at the center of the universe, and all celestial bodies revolve around it.
How do scientists believe the solar system formed?
From a giant rotating cloud of gas and dust that collapsed under its gravity, forming the Sun and planets.
What role do scientists play in developing the Big Bang Theory?
Scientists gather and analyze data, propose hypotheses, and test them with experiments and observations to refine the theory.
How did Galileo's observations support the heliocentric model?
He observed the phases of Venus and the moons of Jupiter, which contradicted the geocentric model.
What is the asteroid belt, and where is it located?
It is a region filled with rocky bodies located between the orbits of Mars and Jupiter.
How can theories change over time and are they widely accepted by everyone?
Introduction to new technologies and new information.
Theories are generally accepted by everyone until it is disproven.
Why did the geocentric model remain accepted for so long?
It aligned with the beliefs and observations of the time, and the Church supported it.
What evidence do we have of the solar system's origins?
Observations of distant star systems forming and the study of meteorites that contain ancient material from the early solar system.
