What is the value of hubble's constant?
The current estimated value of Hubble's constant is around 70 kilometers per second per megaparsec. This means that for every additional megaparsec (about 3.26 million light-years) away a galaxy is from us, it appears to be moving 70 kilometers per second faster due to the expansion of the universe.
How fast is a galaxy 10 billion light years from earth moving away from us?
The Hubble Constant ... relating distance to speed of expansion ... is currently estimatedas 71 kilometers per second per megaparsec. (Plus or minus 10 percent. The numberhas been hotly debated and actively researched for the past 80 years.)1 parsec = 3.26 light years.10 billion LY = 3,067.5 million parsecs (rounded)Speed of recession = (3,067.5 million parsecs) x (71 kilometers per second per megaparsec) =217,800 kilometers per second (rounded)= 72.5 percent of the speed of light (rounded)
How much is the universe expanding each year?
We cannot know for sure, but we're sure that the universe expanded faster than the speed of light. While it is physically impossible for any object to move through space faster than the speed of light (according to Einstein's theory of relativity), it is possible for space itself to expand faster than the speed of light since it is not an object, but the area in which all objects and laws of physics are contained. In fact, space is still expanding faster than the speed of light.

Is it possible that the universe keeps dying and being reborn and we're just experiencing one universe in a much longer possibly eternal string of universes?
That possibility has been considered before. The basic idea is that the Universe collapses due to gravity, and then expands again in the next Big Bang. However, there are several problems with that. For one, the Second Law of Thermodynamics would still apply. In other words, the next universe would be different from the current one, and the cycle could not continue forever. (Note: If you want to understand astronomy, a basic understanding of the Second Law is a must.) Also, this is not supported by observational evidence. For this to happen, the expansion of the Universe would have to slow down over time. The opposite is actually happening: the expansion of the Universe is accelerating.
What is the rate of expansion of the universe in terms of the Hubble constant, which is approximately 70 km per second per megaparsec?
The rate of expansion of the universe is measured by the Hubble constant, which is around 70 kilometers per second per megaparsec.
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.
What is the value of hubble's constant?
The current estimated value of Hubble's constant is around 70 kilometers per second per megaparsec. This means that for every additional megaparsec (about 3.26 million light-years) away a galaxy is from us, it appears to be moving 70 kilometers per second faster due to the expansion of the universe.
What are the units of the Hubble constant?
Oh, that's a great question, friend! The Hubble constant measures the rate of the universe's expansion, isn't that fascinating? It's often expressed in units like kilometers per second per megaparsec, but what's more important is appreciating the awe-inspiring beauty and wonder of the cosmos. Just as we blend colors on our canvas to create harmony, the universe interweaves time and space to make an ever-evolving masterpiece.
What is the rate of acceleration of the Universe?
The rate of acceleration of the universe is determined by the cosmological constant, also known as dark energy. This acceleration is causing the universe to expand at an accelerating rate, leading to an increase in the distance between galaxies over time. The exact value of this acceleration is currently estimated to be around 73 kilometers per second per megaparsec.

71 kilometers per second per megaparsec convert to mph?
71 km/s per megaparsec is an acceleration, not a velocity. Key this into the Google task bar: convert 71 km per second to miles per hour Out pops: In each case this would be the acceleration over a megaparsec (about 3 million light years) Sounds about right for the Hubble Constant.
5795 kilometers per second per megaparsec convert to mph?
5,795 kilometers per second = 12,963,050 miles per hour (rounded)
Is the big bang really over or is the known universe still in the early throws of an explosive expansion - JP?
The term "Big Bang" usually refers to the first few seconds - or even fractions of a second - after what is considered the beginning of the Universe. On the other hand, our Universe is still expanding - in fact, it has been observed that the expansion is getting faster.
Could this be the second or third time around for the universe and could this expansion and collapse all have happened before?
Possibly, however there is no evidence for this (nor is there evidence against it).
What is the current accepted Hubble constant value in cosmology?
Oh- what a beautiful question! The current accepted Hubble constant value in cosmology is around 74 kilometers per second per megaparsec. It represents the rate at which the universe is expanding- just like adding brushstrokes to a scenic canvas, giving depth and dimension to our understanding of the cosmos.
What is happening to the universe since the big bang?
Since the Big Bang, the universe has been expanding. Galaxies are moving away from each other as space itself expands. This expansion is happening at an accelerating rate, driven by dark energy.
