The steady state theory was proposed by:

• Hermann Bondi, Thomas Gold, and Fred Hoyle

• Albert Einstein, Niels Bohr, and Max Planck

• Isaac Newton, Galileo Galilei, and Johannes Kepler

• Stephen Hawking, Carl Sagan, and Neil deGrasse Tyson

occurs when electromagnetic waves shift to shorter wavelengths (shift towards the blue end of the spectrum when the source of the waves is moving closer to the observer).

• Blueshift

• Redshift

• Doppler Effect

• Spectral Shift

this theory states that the universe has no

beginning and no end. suggests that the universe has always been here and will

always be present. It also suggests that the universe always looks the same in any

time or space, but the universe continuously expands while simultaneously creating

matter.

• Big Bang Theory

• Steady State Theory

• Cyclic Universe Theory

• Multiverse Theory

spotted what he thought as a flaring nova star in the M31 nebula or the Andromeda constellation using a Hooker telescope.

• Edwin Powell Hubble

• Carl Sagan

• Galileo Galilei

• Isaac Newton

He then realized that there were indeed traces in the form of cosmic rays. He explained that the cosmic rays were “ashes and smoke of bright but very rapid fireworks,” and they originated when the primeval atom disintegrated. Who is the scientist associated with this explanation?

• Albert Einstein

• Georges Henri Joseph Edouard Lemaître

• Niels Bohr

• Richard Feynman

a Belgian priest, suggested the idea of the expanding universe.

• Georges Henri Joseph Edouard Lemaître

• Albert Einstein

• Isaac Newton

• Galileo Galilei

also known as pulsating theory, proposes that the universe is expanding and will contract once all the energy after the big bang has been used up.

• Oscillating Universe Theory

• Static Universe Theory

• Expanding Universe Theory

• Contracting Universe Theory

This relationship of the velocities of distant objects in the universe in proportion to their distance from Earth is called

• Hubble's Law

• Einstein's Theory

• Newton's Law of Gravitation

• Kepler's Third Law

Drawbacks of Big Bang Theory:

• It failed to explain how the universe was created.

• It provides a detailed account of the universe's origin.

• It explains how galaxies formed from dark matter.

• It describes the exact moment of the Big Bang.

Evidences that Support the Big Bang Theory:

• expansion of universe, high amount of light elements, and detection of cosmic microwave background (CMB) radiation

• steady state theory and constant density of matter

• presence of dark matter and dark energy

• formation of galaxies and clusters in a static universe
