The age of the universe is inversely proportional to the Hubble constant. A smaller Hubble constant would imply a younger universe, while a larger Hubble constant would suggest an older universe. This relationship is based on the assumption that the expansion rate of the universe has been constant over time.

A Hubble constant of 50kmsMpc will make the universe how old?
A Hubble constant of 50 km/s/Mpc corresponds to an age of approximately 13.7 billion years for the universe based on current cosmological models and observations.
What is the age of the universe according to hubble telescope?
The age of the universe according to the Hubble Space Telescope is estimated to be around 13.8 billion years. This estimate is based on observations of the cosmic microwave background radiation and the expansion rate of the universe.
What is the significance of Hubble's constant value in determining the rate of expansion of the universe?
The Hubble constant value is important in determining the rate at which the universe is expanding. It helps scientists understand how fast galaxies are moving away from each other and how the universe is evolving over time.
Describe Two ways scientists calculate the age of the universe?
By measuring the rate of expansion of the universe using the Hubble constant and then calculating backwards to determine when the universe started expanding, scientists can estimate the age of the universe. By studying the cosmic microwave background radiation left over from the Big Bang, scientists can infer the age of the universe by measuring the temperature fluctuations and using them to determine the time since the universe began.
How is the universe changing by red shift?
Redshift in the universe occurs as objects move away from one another, expanding the universe. This indicates that the universe is still expanding, consistent with the Big Bang theory. The rate of this expansion, known as the Hubble constant, provides insight into the age and future of the universe.
Why the age of the universe equals 66.6 percent of hubble time?
The age of the universe is approximately 13.8 billion years, while the Hubble time is around 20.8 billion years. The ratio of the age of the universe to the Hubble time is about 66.3%, not 66.6%. This ratio is due to the expansion rate of the universe changing over time, affecting the relationship between the two quantities.
What would your estimate be for the age of the universe if you measured Hubble's constant to be 11 kilometers per second per million light-years?
Using a Hubble's constant of 11 km/s/Mly would estimate the age of the universe to be approximately 8.9 billion years. This calculation is based on the reciprocal of the Hubble's constant, accounting for the expansion rate of the universe.
What happens if hubble's constant increases?
If Hubble's constant were to increase, it would mean that the rate at which the universe is expanding is also increasing. This could have implications for the age and size of the universe, as well as the eventual fate of the cosmos. Additionally, it could potentially impact our understanding of dark energy and the overall structure of the universe.
How would you work out the Hubble constant if the earth is 12.5 billion years old?
The Earth is not 12 billion years old. It is more like 5 billion years old. Hubble's constant cannot be determined from the age of the Earth. Hubble's constant describes how fast the universe is expanding. It can be determined by looking at the redshifts of stars that are a known distance away. From the redshift, one can determine the velocity of the star. Then Hubble's constant is defined as follows: v=Hd where v is the velocity of the star, H is Hubble's constant and d is the distance to the star. The current accepted value of Hubble's constant is about 71 km/s/Mpc.

How has cosmic background radiation helped us determine the age of the universe?
The CMBR did not reveal anything DIRECTLY about the age of our Universe. However, its spectrum and isotropy are almost perfectly as predicted by a Universe that began to expand about thirteen billion years ago -- a timeline given by the Hubble Constant. As such, it gives extremely strong support to that timeline.

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.
According to the big bang theory shouldn't there be empty space the distance of twice the age of the universe?
Your question presumes that the "fundamental" physical "constants" like the speed of light, the gravitational constant or the Hubble constant are in fact constant, which is a matter of some speculation. We have not noticed them to change, but we've only known that these things existed for a little over 100 years - and the universe is about 14 billion years old. (Any claim to greater accuracy is itself speculative.)
