How did Hubble's discovery that the universe is currently expanding change scientific thought about the size of the universe in the past?
Expansion, run in reverse, is contraction. The universe gets larger as it moves into the future, and smaller as we examine its past. If we go back to the time when the expansion originally began, which was the Big Bang, the universe was very small, perhaps only the size of a proton, or even a singularity of zero volume.
What else can I help you with?
If all galaxies began to show blue shifts what would this change indicate about the fate of the univerese?
That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.That would be a sign that the Universe is contracting, instead of expanding as it currently is.
The discovery that the universe appears to be expanding led to a widely accepted theory called?
The discovery of the expanding universe led to the development of the Big Bang theory, which proposes that the universe originated from a singular event about 13.8 billion years ago. This theory is supported by various pieces of evidence, such as the cosmic microwave background radiation and the observed redshift of distant galaxies.
Is expanding universe accurate?
All the available evidence strongly indicates that the Universe is, indeed, expanding.
What does it mean when someone says the universe is expanding?
Two answers from me. 1. There is more room for possibilities. 2. The big bang theory and how it all went from one little speck to the universe. The discovery channel actually had a show on this once.
How was the cosmoligical constant proved wrong by Hubble?
Hubble's discovery of the expanding universe in the 1920s provided evidence against the static universe model favored at the time, which relied on a cosmological constant to maintain stability. By observing that galaxies were moving away from each other and the universe was expanding, Hubble's findings contradicted the need for a cosmological constant to explain a static cosmos.
Is the universe contracting?
Currently, scientific evidence suggests that the universe is expanding rather than contracting.
The discovery of a red shift in the spectra of galaxies provided evidence that the universe is?
expanding
What was Edwin hubble's most famous discovery?
The universe is expanding!

Is the universe infinate?
Scientists currently believe that no, the universe is not infinite. It is of a finite size however, this finite size is constantly expanding but not expanding AWAY from anything, just expanding
What is important about Hubble discovery that there is a red shift in the spectra of galaxies?

Is the universe expanding or contracting?
The universe is expanding.
How many infinite planets are there in the universe?
There is no definitive answer to how many infinite planets there are in the universe. The universe is vast and constantly expanding, with potentially countless planets beyond what we can currently observe.
What did Edwin Hubbles discovery of red shift demonstrate?
Edwin Hubble's discovery of red shift demonstrated that galaxies are moving away from each other, providing evidence for the expanding universe. This discovery supported the Big Bang theory and fundamentally changed our understanding of the universe's structure and evolution.
Which view of the fate of the universe is currently favored a big crunch or an endless ever expanding universe?
Answer: I don't believe that any consensus has been reached, although it seems that more people are arguing that a "big crunch" is more likely that an endless expansion into increasing entropy. But this is definitely a question that you should ask again in about 15 years. Answer number 2: The ever-expanding Universe. The main reason this seems likely is that it has been observed that the expansion of the Universe is actually accelerating - i.e., it is expanding faster now than in the past. Answer number 3 : I agree with answer 2. The discovery of "dark energy" and the increasing rate of expansion of space favors the ever expanding Universe.
