What happens to a star when it begins to burn more elements?

After the fusion of hydrogen ends, high-mass stars start burning carbon as their next fuel consumption stage. The star that continues to burn heavier elements for longer periods of time will have a greater mass than the main sequence star. Incrediblely massive stars continue to fuse helium until they produce iron (Fe).

What changes in space result from the death of massive stars quizlet?

Stellar dark holes are formed when the center of a massive star collapses on itself. Supernovae, which are explosions of stars, can also cause this collapse, which sends a portion of the star into space. Scientists believe supermassive black hole formation occurred at the same moment as the galaxy they are located in.

Does gravity make a nebula more stable in a newly formed star?

To answer the question: Is gravity able to make a nebula in a new star stable? It is false. The nebula will become more chaotic the larger the stars within it, which will continue until it collapses completely.

How do scientists know that dark matter exists quizlet?

we conclude that dark matter exists because of its gravitational effect on all matter we can see. Scientists believe it is unlikely that there is something wrong with our understanding gravity. This rule excludes the possibility of misinterpreting gravity to infer dark matter’s existence.

What is most needed for cosmologists to study the age of the universe?

According to cosmologists, all the _____________________ that exists is all that there will ever be. Which one of the following is most necessary for cosmologists in order to study the ageing of the universe? Dark energy.

Does the Milky Way include a planetary system?

The Milky Way Galaxy is one of many billions of galaxies throughout the universe. Within it, there are at least 100 billion stars, and on average, each star has at least one planet orbiting it. This means that there could be thousands of planetary system like our solar system in the galaxy.

What happens at the edge of the universe?

There is an edge to the universe that we can only see as far as our eyes can see. Because light travels at a finite rate (one light-year per annum), we can only see so far away that we are also looking backwards in time. Eventually we see what was happening almost 14 billion years ago, the remnant radiation from the Big Bang.

How do we know the universe is infinite?

First it is still possible that the universe has a finite size. Although the universe is vast, it does have limits. That’s because we know the universe isn’t infinitely old — we know the Big Bang occurred some 13.8 billion years ago. That means that light has had “only” 13.8 billion years to travel.
