Could the ages of globular clusters be used to place a limit on the maximum value of the Hubble constant?

The value of the Hubble Parameter varies with time and so should not be called a constant. It is not a constant. However its value does not change appreciably in...

Hubble's law has to do with the . Space is expanding, every portion of it receding from every other, and the more distant two objects are, the faster they recede...

The dimension of Hubble constant, $[H_o]-LL^(-1)T^(-1)=T^(-1)$. The dimension of thr reciprocal $[1/H_o]=T$ As of now, different estimates of $H_o$ have a range around 70 km/s/mega parsec. The reciprocal, after unit...

The Hubble Constant simply states that the greater an object's distance, the greater its red shift will be.

So such stars can be used as standard candles to calculate distance to globular clusters.

The Hubble telescope collects data in analog form. That is because it is a concave mirror which collects light wave and sends them in a focused form to its receivers....

Hubble is not like a regular digital camera in that it doesn't take a single image in one shot. The Hubble's CCD cameras can take monochrome images at a resolution...

The stars in globular clusters follow a distinct pattern on the Hertzsprung Russell diagram. Blue stragglers don't follow the pattern as they are too big. The most likely theory is...

Explaining in the form of points:- =>They are a collection of densely packed ancient stars. =>There are 150 million clusters in the Milky Way. =>Contain thousands or even millions of...

A type 1a supernova is possible in a globular cluster. Stars ins globular cluster evolve into a white dwarfs. If a white dwarf is in a close binary with a...
