Edwin Hubble demonstrated that distant galaxies existed by measuring which type of stars?
Edwin Hubble used Cepheid variable stars to measure the distances to galaxies. These stars have a relationship between their luminosity and pulsation period, allowing astronomers to calculate their distance based on their observed brightness.
What is the relationship between a planet's distance from the sun and the planet's period of revolution?
The relationship between the planet's SPEED and its distance from the Sun is given by Kepler's Third Law.From there, it is fairly easy to derive a relationship between the period of revolution, and the distance.
What do th spectra of distant galaxies collected today say about hubbles original findings?
The spectra of distant galaxies collected today support Hubble's original findings by showing that galaxies are moving away from us, indicating an expanding universe. The redshift in the spectra is evidence of this cosmic expansion, consistent with Hubble's discovery of the relationship between distance and redshift.
Is the relationship between distance and force in Newton's law of universal gravitation a negative correlation?
No. "Negative correlation" means no relationship can be found between the two quantities. But in the case of the gravitational force, there is a definite, bullet-proof, mathematical connection between the distance and the force. Since a greater distance leads to a smaller force, the relationship is said to be "inverse", but the correlation is definitely not "negative".
What two quantities did Edwin Hubble compare to discover the expansion of the Universe?
Edwin Hubble compared the distances to galaxies (based on their brightness) and their redshifts (due to the Doppler effect) to discover the expansion of the Universe. By finding a relationship between these two quantities (dubbed Hubble's Law), he provided evidence that the Universe is expanding.
What is it when galaxies move away at a speed proportional to their distance?
This phenomenon is known as Hubble's Law, which describes the relationship between the distance and the velocity at which galaxies are moving away from us. It is a key piece of evidence for the expansion of the universe.
What is the relationship between the expanding universe and the distances between stars and galaxies?
This is mostly theory, Galaxies are made of billions of stars. For some reason Galaxy's hold on to their stars. We do not really understand how galaxy's can yet hold their form like this. Our math so far has trouble with making sense of this. When comparing one galaxy to another, size becomes so large words are hard to describe the distance of space. There is an an incredible amount of space between everything out there. What is the distance between galaxies, why is it there, The expanding universe is trying to explain the growing spaces between galaxies yet the galaxies appear to stay bound to themselves.
Distance between galaxies?
billions of miles.
how distance to a galaxy and speed are related?
Relationship between distance of galaxy and its speed is that galaxies are moving away from the Earth at velocities proportional to their distance. In other words, the further they are the faster they are moving away from us.
Is your sun and other stars far away in another galaxy too far to feel a gravitational force between them?
Galaxies do exert significant gravitational attraction on other galaxies. For example, the Greater and the Lesser Magellanic Clouds are galaxies that orbit our own galaxy, the Milky Way. In that sense, the stars in one galaxy do have a gravitational interaction with those in other galaxies. Of course, the more distant galaxies have correspondingly less gravitational interaction with ours.
What is the term for the relationship between the distance?
um Long-distance relationship?
What is happening to the distance between galaxies because of the big bang?
The distance is getting larger as the universe expands.

What is the distance between galixies?
millions of light years The typical distance between galaxies is only about 20-40 times the sizes of a galaxy.
Who classified the galaxies according to shape and distance and concluded that galaxies move away from each other at a rate dependent to the distance between them?
Edwin Hubble, in the 1920s. Later they named a telescope after him.
What is the significance of the distance between galaxies in understanding the vastness of the universe?
The distance between galaxies is significant in understanding the vastness of the universe because it shows the immense scale of the cosmos. The vast distances between galaxies highlight the sheer size and expanse of the universe, giving us a sense of how small and interconnected we are in the grand scheme of things.
