How can scientists estimate the age of the universe? How does this estimate take into account Einstein's Theory of Relativity?

Expert Solution

By dividing the estimated size of the universe by the speed of light an approximate number for the age of the universe can be determined.

Accounting the theory of relativity the speed of light is a constant so the speed of light can not change. It makes sense that D/V=T

Since V×T=D

This makes perfect sense at normal Velocities.

What these calculation failed to take into account is that Einstein's theory of relativity speaks of time as being relative. At the speed of light time ceases to exist. A photon can be created millions of light years away and instantly appear somewhere else. So while the speed of light is constant the time it takes light to travel is not.

Why does Quantum Mechanics not follow Einstein's Theory of General Relativity? If that's completely true, [we know that "The Higgs boson does not technically give other particles mass. More precisely, the particle is a quantized manifestation of a field (the Higgsfield) that generates mass through its interaction with other particles." ] will it follow the famous equation E=mc²?

10. The Hubble Age. Let's estimate the age of the universe. Pick two galaxies, one 10 Mpc away, and one 100 Mpc away. Calculate how fast each one is moving away from us, assuming a Hubble constant of 70 km/sec/Mpc. Assume they have always been moving at that speed and calculate how long (in years) it has taken them to reach their present distance. Because the expansion is uniform, it shouldn’t matter which galaxies you use. What is your estimate...
