- Have you ever thought about visiting the universe? Or have over viewed it? It is amazing how scientists are able to make discoveries about the universe. Incredibly, scientists have invented special instruments that can tell wether an object is moving away from Earth or towards it, and they also made many other such instruments. Yet, there are many questions an average person would ask such as, How was the universe formed, how old is the universe, and will the universe expand forever?
The universe is a huge wide open space that holds everything from the smallest particle to the biggest galaxy. Isn't that crazy? For the question many that many were asking, scientifically, about 13.7 billion years ago, a powerful explosion happened called …show more content…
Since the universe was formed 13.7 billion years ago, how old do you think the universe is? How did scientists determine how many candles to put on the universe's birthday cake? They can determine the age of the universe using two different methods: by studying the oldest objects within the universe and measuring how fast it is expanding. Experts agree that the universe cannot be younger than the objects contained inside of it. By determining the ages of the oldest stars, scientists are able to put a age limit on the universe which is 13.7 billion years old.
A forever expanding universe? The expansion of the universe depends on how much matter the universe contains. Scientists predict that if there is enough mater, gravity could eventually stop the expansion of the universe. If the universe stops expanding, it could start collapsing to its original state. This process would be a reverse of what might have happened during the big bang. However, scientists now think that there may not be enough matter in the universe, so the universe will continue to expand forever. Therefore, stars will age and die, and the universe becomes cold and dark after many billion of years. Even after the universe becomes cold and dark, it will continue to expand
