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 is the difference between big bang theory and big crunch theory?
The big bang theory is the explosion that started the universe. Where as the big crunch is the theory where the universe will eventually contract and become increasingly clumped and eventaully all mater would collapse into black holes which would then coalesce producing a unified black hole or Big Crunch singularity.
When did Hubble discover that the universe was expanding?
Edwin Hubble discovered that the universe was expanding in 1929 when he observed that distant galaxies were moving away from us, as indicated by their redshift in their spectral lines. This discovery led to the formulation of Hubble's law, which describes the relationship between a galaxy's distance and its velocity of recession.
Is the universe infinitely expanding?
Hey there, friend. üåü Yes, the universe is indeed expanding, like a canvas gaining more and more space between points. Just like in a painting, this process allows for new regions to bloom and evolve in beautiful ways. Just imagine all the happy little galaxies moving further apart and creating amazing cosmic masterpieces!
How can the universe be expanding if it is infinite?
Oh, that's a happy little puzzle there, friend! The way I see it, imagine you're painting a lovely galaxy full of stars. Now, just because the canvas is infinite and your paint keeps going doesn't mean your beautiful creation can't keep growing and blooming. So, think of the universe expanding like those stars twinkling and spreading out, bringing new colors and light to this vast cosmic masterpiece. Trip on that, and let's make some cosmic happy clouds together!
How the size of the universe changed not the size or mass of the earth JUST the universe?
The Universe is continuously expanding. The distance between galaxies increases. The amount of space in the Universe increases.
If universe is expanding but mass of sun and planets is not then shouldn't gravity be reduced due to space-time and mass relation?
The answer is that the expansion of the universe is only noticeable over distances of hundreds of millions of light years or more. Over the much smaller distances found within galaxies and planetary systems its effects are negligible.
What did the early astronomers think the difference between the solar system and the universe?
They thought it was a explosion in the universe so they sent astronauts into space.
How far is the earth from the big bang theory?
Contrary to what is often portrayed in popular presentations of the Big Bang, the event was NOT an explosion of dense matter into empty space. It wasn't an explosion of ANYTHING. It was an expansion of space itself -- and it was NOT expanding into anything. In other words, the expansion took place at all parts of our Universe at the same time. Our Earth is as much at the center of the Big Bang as every other point in our Universe.

What does the universe expanding mean?
The distance between galaxies is increasing, pretty much in all directions. This suggests that space itself is expanding. We also now know the rate of expansion is in fact increasing.

A gravitional exists between you and every object in the universe?
yes, but most gravitational pulls are only noticeable if the object is enormous, for example, Earth.
What is the theory of the beginning of the universe called the?
The big bang theory which is a theory of cosmology holding that the expansion of the universe began with a gigantic explosion between 12 and 20 billion years ago
Are most galaxies spread uniformly throughout the universe?
Galaxies are not spread uniformly throughout the universe. They are actually structured into clusters, groups, and superclusters, with vast voids of empty space in between. This distribution is influenced by gravity and the large-scale structure of the universe.
What is the difference between big bang theory and big crunch theory?
The big bang theory is the explosion that started the universe. Where as the big crunch is the theory where the universe will eventually contract and become increasingly clumped and eventaully all mater would collapse into black holes which would then coalesce producing a unified black hole or Big Crunch singularity.
How time is affected between the galaxies as there is no mass there?
In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.In fact, galaxies have an enormous mass.
