Stellar evolution

We may see thousands of stars in the dark sky. Our universe consists of billions of stars. Stars may appear tiny to us but they are huge balls of gasses. Sun is a star of average size. Some stars are even a thousand times larger than the sun. The stars do not exist forever they have a certain lifetime. The life span of the sun is about 10 billion years. The star undergoes various changes during its lifetime, this process is called stellar evolution. The structure of the sun-like star is shown below.

Red Shift

It is an astronomical phenomenon. In this phenomenon, increase in wavelength with corresponding decrease in photon energy and frequency of radiation of light. It is the displacement of spectrum of any kind of astronomical object to the longer wavelengths (red) side.

Explain using gravity and the conservation of angular momentum, why the galaxy today is a flat disc that rotates faster.

There is still some uncertainty in the Hubble constant. (a) Current estimates range from about 19.9 km/s per million light-years to 23 km/s per million light-years. Assume that the Hubble constant has been constant since the Big Bang. What is the possible range in the ages of the universe? Use the equation in the text, T0=1H , and make sure you use consistent units. (b) Twenty years ago, estimates for the Hubble constant ranged from 50 to 100 km/s per Mps. What are the possible ages for the universe from those values? Can you rule out some of these possibilities on the basis of other evidence?

The law of conservation of energy states that energy can be converted from one form to another but cannot be created or destroyed. Therefore, the amount of energy in the universe is constant. In your initial post to the discussion, respond to the following prompts: What do you think would happen if energy were not conserved? Think of (and share) two scenarios in which our lives would be drastically altered if this law of conservation was not in place. At least one of your scenarios should be at the molecular level. Would the implications be positive? Negative? Explain.
