What did Fred Hoyle believe in?
Hoyle believed that as new matter forms, the universe expands without end because it is infinite in space and time and the galaxies tend to space themselves more widely apart. As they do so, new galaxies form at such a rate that their average density in space remains unchanged with time.
What was Fritz Zwicky hypothesis?
In 1937, Zwicky posited that galaxies could act as gravitational lenses by the previously discovered Einstein effect. It was not until 1979 that this effect was confirmed by observation of the so-called “Twin Quasar” Q0957+561.
What did Henrietta Leavitt discover?
Henrietta Swan Leavitt’s contribution to the field of astronomy is that she gave us the tools to map out the stars in the universe. She discovered the correlation between Period and Luminosity. This helped turn the sky into a three-dimensional map allowing astronomers to solve the unknown in the equation: Distance.

What did Fritz Zwicky discover about dark matter?
In the 1930s, he noticed that galaxies within clusters were zooming around far quicker than their mass would logically dictate. So he figured that there must be some extra mass in there. Some sort of dark invisible matter slurping around the universe. He imaginatively called this dark matter dark matter.
What caused Copernicus to jail?

What did Henrietta Leavitt do for a living?
Henrietta Leavitt was an astronomer who opened the door to a dramatic enlargement in the size of the known universe. She found that a certain type of star, the Cepheid variable, pulses at a rate that’s related to its brightness. A Cepheid variable star’s pulse rate reveals the star’s true, fundamental brightness.
