- As per Hubble's law, the universe is expanding. The recessional velocity of galaxies is directly proportional to the distance. The farther they are, the faster they are moving away from Earth. This is known as Hubble's law.
- This gives us the age of the universe and can be derived from Hubble's law. This time also known as Hubble's time is given by,
Here H0 is the Hubble's constant.

- Please list 4 different forms of energy present in the universe?Prob. 4 A 1.2m-long metal bar is pulled to the right at a steady rate of 2.5m/s perpendicular to a uniform, 1.50T magnetic field. The bar rides on a pair of conducting, parallel rails connected through a resistance R = 7.5N so the apparatus forms a complete electrical circuit. Ignore the resistance of the bar and the rails and all gravitational effects. [b]What is the magnitude of the induced current (in units of A)?Calculate the Hubble constant for a universe that is 20 billion years old.
- Need help, need to know if I'm doing this rightIf you observe light emitted from a distance object when the cosmic background temperature was Tz=54K, what is the redshift z of that light? At that redshift, what was the diameter Dz of the universe at that time compared to the diameter of today's universe D0?
