Technological advances mean that astronomers are able to see more and more detail in the universe - and better understand it's composition. For example - it was originally thought that the Earth was the centre of the universe... we now know, through the invention of the telescope etc - that this is not so.

Why do scientists study distant galaxies to learn about galaxies?

Scientists study distant galaxies to understand the formation, evolution, and properties of galaxies over time. By observing galaxies that are far away, they can explore the universe at different epochs and gain insights into how galaxies have changed and evolved since the early universe. Studying distant galaxies also helps scientists refine theories about the laws of physics and the nature of the universe as a whole.

Ptolemy was the Roman astronomer who incorrectly argued that Earth was the center of the universe in his geocentric model. His theories dominated Western thought for over a thousand years.


Is evolution something to do with the big bang?

No, the Big Bang theory explains the early stages of the universe's expansion, while evolution is the process by which living things change over time through genetic variation and natural selection. The two concepts are related in the sense that the universe's development set the stage for life to evolve on Earth, but they are distinct scientific theories.


How cosmic microwave background radiation shows us the universe is changing?

It shows that at the beginning of time all radiation was trapped in a small place and since the universe has expanded and cooled so has the radiation which is why it has dropped from very high radiation to its fairly low microwave radiation state. Today. It is the afterglow of the universe which heavily backs up the big bang theory.


Who invented the world?

The concept of the world as we know it was not invented by any one person. The world's existence and formation is attributed to natural processes and scientific theories such as the Big Bang theory for the creation of the universe and Earth's formation over billions of years.
