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.
If a constant apparent speed of 1.54 km s by how many megaparsec would the separation between us and a galaxy change over the course of 2.0 billion years?
Assuming a constant speed of 1.54 km/s, the separation between us and the galaxy would change by approximately 2.3 megaparsecs over 2.0 billion years. This calculation is based on the formula Distance = Speed x Time, converting the distance from kilometers to megaparsecs.
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.
The distance of 3.3 million light years is also termed?
3.3 million light years is also termed as the distance of 1 megaparsec.
How many kilometers to the center of the earth?
That would be the radius of the earth which is:6,378.1 kilometers
How many km are in megaparsec?
1 megaparsec = 3.08568*1019 km.
How far is a megaparsec in miles?
According to Wikipedia, a parsec is 30 trillion kilometers. So, a megaparsec is 30 million trillion kilometers. And, since there are about .62 miles in a kilometer, a megaparsec is about 19 million trillion (or quintillion) miles. More precisely, 1 parsec = 3.08568025 x 10^16 meters. So, 1 megaparsec = 10^6 * 3.08568025 x 10^16 meters or 3.08568025 x 10^22 meters. Converting to kilometers, a megaparsec is 3.08568025 x 10^19 kilometers. Converting to miles, a megaparsec is .621371192 * 3.08568025 x 10^19 miles or 1.91735282 x 10^19 miles. This is equivalent to 19.1735282 x 10^18 miles. Since 10^18 is a million trillion (or quintillion), 1 megaparsec = 19.1735282 million trillion miles.
5795 kilometers per second per megaparsec convert to mph?
5,795 kilometers per second = 12,963,050 miles per hour (rounded)
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 many cubic angstrom units are there in a cubic megaparsec?
1 parsec = 3.0857x1016 metres = 3.0857x1026 Angstrom units.So, 1 megaparsec = 3.0857*1032 Angstrom units.And then, cubing them,1 cubic megaparsec = 2.938x1097 cubic Angstrom units.
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.

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 length from largest to smallest?
Megaparsec . . . Femtometer
If a constant apparent speed of 1.54 km s by how many megaparsec would the separation between us and a galaxy change over the course of 2.0 billion years?
Assuming a constant speed of 1.54 km/s, the separation between us and the galaxy would change by approximately 2.3 megaparsecs over 2.0 billion years. This calculation is based on the formula Distance = Speed x Time, converting the distance from kilometers to megaparsecs.
What is a megaparsec?
A megaparsec is a unit of length used in astronomy to measure extremely large distances. It is equal to one million parsecs, where 1 parsec is approximately 3.26 light-years. Megaparsecs are commonly used to describe distances between galaxies or clusters of galaxies.
What is the greatest customary unit to measure capacity?
Probably the cubic megaparsec.
