Three key pieces of observational evidence lend support to the Big Bang theory: the measured abundances of elements, the observed expansion of space, and the discovery of the cosmic microwave background (CMB). The CMB refers to the uniform distribution of radiation that pervades the entire universe.
Which evidence best supports the Big Bang theory?
Two major scientific discoveries provide strong support for the Big Bang theory: ? Hubble?s discovery in the 1920s of a relationship between a galaxy?s distance from Earth and its speed; and ? the discovery in the 1960s of cosmic microwave background radiation.
What are the four pieces of evidence for the Big Bang?
The growth and evolution of galaxies and large-scale structure in the Universe, measurements of the expansion rate and temperature changes over the Universe?s evolutionary history, and the measurement of the abundances of the light elements all matched within the framework of the Big Bang.
What evidence supports the Big Bang radiation?
The cosmic microwave background radiation and the cosmological redshift-distance relation are together regarded as the best available evidence for the Big Bang theory.
What is the evidence for an accelerating universe quizlet?
The major evidence for the idea that the expansion of the universe is accelerating comes from observations of: white dwarf supernovae.
What type of evidence does cosmic background radiation provide about the origins of the universe?
Their detection of the Cosmic Microwave Background (CMB), the radiation left over from the birth of the universe, provided the strongest possible evidence that the universe expanded from an initial violent explosion, known as The Big Bang.
What evidence supports an acceleration in the expansion rate of the universe?
Evidence supporting the universe?s accelerating expansion originally came from observing the explosions of distant stars. Physicists attribute this accelerating expansion to the influence of a poorly understood phenomenon known as dark energy.
What is the primary evidence for an accelerating universe?
The unexpected faintness of high-redshift Type Ia supernovae (SNe Ia), as measured by two teams, has been interpreted as evidence that the expansion of the universe is accelerating.
What is the evidence for an accelerating universe what is the evidence for an accelerating universe?
Observations of supernova explosions halfway back to the Big Bang give plausible evidence that the expansion of the universe has been accelerating since that epoch, approximately 8 billion years ago and suggest that energy associated with the vacuum itself may be responsible for the acceleration.
