Hubble observed that distant galaxies were moving away from Earth, which he noted through the redshift of their light spectra. This redshift indicated that the wavelengths of light were stretched, implying these galaxies were receding from us. Hubble also found a linear relationship between the distance of galaxies and their recessional velocity, leading to the conclusion that the universe is expanding uniformly in all directions. This pivotal discovery became known as Hubble's Law.
What else can I help you with?
What theory is Edwin Hubble the founder of?
Edwin Hubble is the founder of the Big Bang theory, which describes the origin and evolution of the universe. His observations of galaxies and their redshifts led to the formulation of Hubble's Law, demonstrating that the universe is expanding. This groundbreaking work provided strong evidence for the idea that the universe began from a hot, dense state and has been expanding ever since.
What did Edwin Hubble discover in 1927?
universe is expanding
What scientist first established that the universe is expanding?
Edwin Hubble
Lemaitre (based on Hubble's observations) was the first to suggest the?
Lemaître, based on Hubble's observations, was the first to propose the idea of an expanding universe, leading to the formulation of what is now known as the Big Bang theory. He suggested that the universe began from a "primeval atom," which exploded and has been expanding ever since. This concept challenged the then-prevailing static model of the universe and laid the groundwork for modern cosmology. Lemaître's insights significantly contributed to our understanding of the origins and evolution of the cosmos.
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 did hubble conclude when he noted that light emitted from stars is shifting toward the red end of that electromagnetic spectrum?
(A) The universe is expanding.
What did Hubble conclude when he noted that light emitted from stars is shutting toward the red end of the electromagnetic spectrum?
The universe is expanding.
What did Hubble conclude when he noted that light emitted from stars is shifting toward the red end of the electromagnetic spectrum?
He concluded that the universe is expanding.
Who stated that the universe is still expanding?
Hubble did not conclude that the Universe is expanding. Hubble thought the red shift indicated a unrecognized principle of nature. Hubble's constant actually shows the universe is bounded at R=150kMpc/31 and H= c/R = 62km/s/Mpc. The increase red shift velocity indicates a decreasing universe.
Is this universe closed?
As proven by Edwin Hubble, the universe is expanding.
