What do dots represent in your model?
The dots represent the electrons in the outer energy level (valence electrons) from the energy level models. The only electrons hydrogen and helium have are valence electrons. All the other dot structures should have fewer electrons than the energy level model because the dot model only shows the outermost electrons.
What is steady state theory Brainly?
it is a view that the universe is always expanding but maintaining a constant average density, with matter being continuously created to form new stars and galaxies at the same rate that old ones become unobservable as a consequence of their increasing distance and velocity of recession.
Why was the steady state theory abandoned?
We find that Einstein’s steady-state model contains a fundamental flaw and suggest that it was abandoned for this reason. We also suggest that he declined to explore a more sophisticated version because he found such theories rather contrived.
What makes the steady state theory unacceptable?
The Universe is observed to be expanding, so if the density remains the same, matter must be continuously created. This radical assumption is not the reason that the Steady State model is now rejected. The Steady State model has no adjustable parameters to correct for this error, but the Big Bang does.
Is the steady state theory true?
The weight of evidence against the steady-state theory has convinced most modern astronomers that it is incorrect. The steady-state theory does, however, still stand as a major intellectual achievement and as an important part of the history of the development of cosmology in the twentieth century.
What theory discusses that the universe has no beginning and end?
The catch – according to astrophysicist Brian Koberlein – is that, without the singularity, this model predicts that the universe had no beginning. It existed forever as a kind of quantum potential before collapsing into the hot dense state we call the Big Bang.
What happens if the universe ends?
If the Universe holds enough matter, including dark matter, the combined gravitational attraction of everything will gradually halt this expansion and precipitate the ultimate collapse. Over time, galaxies, then individual stars, will smash into each other more frequently, killing off any life on nearby planets.
