First thing to know: the weight of present observational evidence is that our Universe is NOT closed (ie, it will not contract back on itself) but will, instead, expand forever.
The first person to use the mathematics of General Relativity to show that our Universe can be either closed or open was Alexander Friedmann. His work was purely mathematical, and he made no attempt to discern which solution is an accurate description of our Universe.
In 1931, Edwin Hubble showed that our Universe was expanding. Since then, scientists have tried to discern whether this expansion would lead to an open universe or a closed one. Over the decades, scientists were surprised at just how close to either possibility our Universe happened to be -- it was like somehow threw a ball onto the top of the Empire State Building, at the ball just happened to land such that it balanced perfectly on the top.
In 1998, observational evidence showed beyond a doubt that the expansion rate of our Universe is increasing over time. Thus, we happen to live in an open universe.
What else can I help you with?
Is the universe open or closed and how do you know?
Our universe is closed.Answer2: The Universe is closed. The proper theory of Gravity shows this to be true mathematically and through Boundary constants. Gravity Energy is four dimensional quaternion Energy E = - mu/r + mcV. The quaternion derivative of E is bounded ,0 = (d/dr + Del)( -mu/r + mcV)The power of the closed Universe is P = c5/G = 3645E49.
In the big bang theory what describes a universe that will stop expanding and begin to contract?
A closed universe with enough matter to generate sufficient gravitational pull may stop expanding and eventually begin to contract, leading to a "big crunch" scenario where everything collapses back into a singularity. This contraction is driven by the gravitational attraction of matter in the universe pulling everything back together.
How many extrasolar planets are there in this this universe?
As of now, there are over 4,000 confirmed extrasolar planets, also known as exoplanets, in our universe. This number is constantly growing as new planets are discovered through various astronomical techniques.
Does conservation of angular momentum disprove the big bang?
No, This assumes that the universe is a closed system, while this seems a reasonable hypothesis, the modern big bang theory actually states outright that the universe is not a closed system. Conservation of energy is also violated in the current model, the total energy of the universe is increasing.
What did Isaac newton discover about universe?
Isaac Newton discovered the laws of motion and the law of universal gravitation, which revolutionized our understanding of the universe. His work laid the foundation for classical mechanics and provided a framework for understanding the motion of objects in space.
The universe is said to be closed if?
it will either be open or closed universe look it up
Is the whole universe discovered?
Not every galaxy, star, and corner of the universe has been discovered, but we have discovered the universe as a whole. ------------------------- Most likely we never will since the universe is expanding at approximately 40 miles per second.
When did Johannes Kepler discovered the universe?
Nobody discovered the universe. We have always known that the universe exists. Discoveries of how the universe works and what it is have been made by many people.
Who discovered universe?
The universe was discovered by ancient Greeks and Indians, when theories of an impersonal universe governed by physical laws were first proposed.
Is this universe closed?
As proven by Edwin Hubble, the universe is expanding.
A universe that expands and comes back together repeatedly?
a closed universe.
Why is WWE universe closed?
It isn't
What is the difference between an open universe and a closed universe?
there is no difference. they are both 42.
Can to play Lego universe when its closed?
Sadly no!
The idea that the universe is expanding was discovered in the late 1920s by?
It was discovered by Hubble.
Who discovered worm holes in the universe?
Worm holes have not been discovered.
Is the universe a closed system?
No, the universe is not a closed system. It is constantly interacting with external forces and energy, such as from other galaxies or dark energy, which means it is an open system.
