It was believed for quite a while that gravity would slow the expansion of the Universe down. But it is now known that the Universe is expanding faster and faster (apparently it tends towards an exponential growth), so there must be something else, that is pushing the Universe apart, more strongly than gravity can it together. This "something" is called "dark energy".
What else can I help you with?
In the universe what is the red shift?
The alterations to the electromagnetic spectrum caused by the expansion of the universe.
What does the redshift tell us about the universe?
Redshift is a phenomenon where light from distant galaxies appears redder than expected due to the expansion of the universe. It tells us that the universe is expanding and provides evidence for the Big Bang theory. By studying the redshift of galaxies, scientists can understand the rate of expansion and the age of the universe.
What is 'Pulsating theory' and 'Steady state theory'?
Pulsating Theory According to this theory, the universe is supposed to be expanding and contracting alternately i.e. pulsating. At present, the universe is expanding. According to pulsating theory, it is possible that at a certain time, the expansion of the universe may be stopped by the gravitational pull and the may contract again. After it has been contracted to a certain size, explosion again occurs and the universe will start expanding. The alternate expansion and contraction of the universe give rise to pulsating universe.
What is a universe that expands and comes back together repeatedly?
A cyclic universe is one that expands and contracts in a never-ending cycle, repeating the process of expansion and contraction indefinitely. This theory suggests that the universe goes through phases of expansion, followed by contraction, ultimately leading to a big crunch, and then starting the cycle again with a new big bang.
What in space goes on forever?
One thing in space that goes on forever is the expansion of the universe. The universe is constantly expanding, with galaxies moving away from each other at increasing speeds. This expansion is not constrained by any known boundaries or limits.
What is gravitys role in the structures of galaxies?
It's what holds them together. (what's it like in your universe? ... since you're implying that yours is different.)
When was Feeling Gravitys Pull created?
Feeling Gravitys Pull was created in 1985.
What forces causes the expansion?
The expansion of the universe is primarily driven by dark energy, a mysterious force that is causing the rate of expansion to accelerate. Gravity, the attractive force between objects with mass, also plays a role in shaping the large-scale structure of the universe.
In which Direction is nearly all galexies moving in?
Nearly all galaxies in the universe are moving away from each other due to the expansion of the universe. This is known as the expansion of the universe or Hubble expansion.
Does dark matter/energy responsible for the expansion of the universe?
Yes. Dark energy is responsible for the expansion of the universe.
The mysterious force that may be causing the expansion of the universe to accelerate is called?
The current state of affairs with regard to the expansion of the universe point to dark energy as the cause of the expansion of the universe. It is not a force though.
How is it possible that the expansion of the universe is faster than the speed of light?
Relativity theory establishes a speed limit for objects travelling through space - but the expansion of the universe is the expansion of space. There is no speed limit for that expansion.
How fast is the expansion of the edge of the universe occurring?
The expansion of the edge of the universe is happening at a rate of about 46 miles per second per megaparsec.
In the universe what is the red shift?
The alterations to the electromagnetic spectrum caused by the expansion of the universe.
What is the significance of the Hubble radius in understanding the expansion of the universe?
The Hubble radius is important in understanding the expansion of the universe because it represents the distance at which objects are receding from us faster than the speed of light due to the expansion of space. This boundary helps us determine the rate of expansion and the age of the universe.
What is an accelerating universe?
An accelerating universe is a theory which describes and seeks to explain the increasing rate of the expansion of the universe.
What is accelerating universe?
An accelerating universe is a theory which describes and seeks to explain the increasing rate of the expansion of the universe.
