Edwin Hubble based his thinking on several key pieces of evidence, notably his observations of distant galaxies and their redshifts. He discovered that most galaxies are moving away from us, with their light shifted to longer wavelengths, indicating an expanding universe. This led him to formulate Hubble's Law, which correlates the distance of a galaxy with its recessional velocity. His findings challenged the prevailing view of a static universe and provided crucial support for the Big Bang theory.

What made Hubble think the universe was expanding?
Hubble observed that galaxies were moving away from each other, indicating that the universe is expanding. He discovered a relationship between a galaxy's distance from Earth and its velocity, known as Hubble's law, providing evidence for this expansion.
What piece of evidence was suggested by Edwin hubble?
Edwin Hubble suggested the evidence of an expanding universe based on his observation of galaxies moving away from each other with increasing speed. This observation led to the development of the Big Bang theory, which proposes that the universe began as a single point and has been expanding ever since.
How was the evidence for hubble law collected?
The evidence for Hubble's Law, which shows the relationship between distance and recession velocity of galaxies, was collected through observing the redshift of light from galaxies. Astronomers used spectroscopy to measure the redshift of galaxies, which is caused by the Doppler effect as the galaxies move away from us. By studying the redshift of galaxies at different distances, astronomers were able to support the idea that the universe is expanding.
What has the Hubble telescope discovered?
The Hubble telescope has made numerous groundbreaking discoveries, including determining the rate of expansion of the universe, discovering new exoplanets, capturing images of distant galaxies, and providing evidence for the existence of dark matter.
what is the Hubble effect?
The Hubble effect, also known as Hubble's Law, describes the observation that galaxies are moving away from us, and their speed is proportional to their distance from Earth. This phenomenon is a key piece of evidence for the expanding universe theory, indicating that the universe has been expanding since the Big Bang. The relationship is expressed mathematically as ( v = H_0 \times d ), where ( v ) is the velocity of a galaxy, ( H_0 ) is the Hubble constant, and ( d ) is the distance to the galaxy. The Hubble effect provides crucial insights into the dynamics and evolution of the cosmos.
Who gave evidence of the big bang theory?
edwin hubble
What measurement was Edwin Hubble famous for?
Edwin Hubble was famous for measuring the red shift of distant galaxies and interpreting that as evidence of the expansion of the Universe.
The best evidence that the big bang theory was real?

What made Hubble think the universe was expanding?
Hubble observed that galaxies were moving away from each other, indicating that the universe is expanding. He discovered a relationship between a galaxy's distance from Earth and its velocity, known as Hubble's law, providing evidence for this expansion.
Who gave the first evidence of the Big-Bang theory?
Edwin Hubble showed that the red-shift of distant galaxies was as predicted by Georges LeMaitre's hypothesis, which was later named the Big Bang.
What piece of evidence was suggested by Edwin hubble?

This observation led to the development of the Big Bang theory, which proposes that the universe began as a single point and has been expanding ever since.

What evidence is collected in support of the big bang theory?
expansion of the universe as shown by the Hubble constant3K universal microwave background radiationetc.
What is Edwin Hubbles key contributes and evidence on galaxies?
Edwin Hubble is renowned for demonstrating that galaxies exist beyond our Milky Way, fundamentally reshaping our understanding of the universe. His key contributions include the classification of galaxies and the formulation of Hubble's Law, which shows that the universe is expanding, with galaxies moving away from us at speeds proportional to their distances. This discovery provided strong evidence for the Big Bang theory and established the field of extragalactic astronomy. Hubble's observations, particularly with the Hubble Space Telescope, have been pivotal in advancing our knowledge of the structure and evolution of the cosmos.
