.. looking at these numbers:
- Speed of Earth’s rotation, at the equator — 1670 km per hour. (source1, source2)
- Speed at which Earth revolves around the Sun — 30 km/s or 108000 km/hr.
- Speed at which the entire Solar System is orbiting around the center of milky way galaxy — 220 to 270 km/s. It takes the solar system about 225 to 250 million years to complete one orbit of the galaxy (a ‘galactic year’). (source, source2)
- The universe itself is expanding, and the speed at which the ‘Local Group’ (the cluster of galaxies to which milky way belongs) is traveling — 600 km/s. (source1, source2)
- Number of stars in Milky way galaxy is estimated to be 200 – 400 billion. (source, source2)
- The number of galaxies in the universe is very roughly estimated to be 100 – 200 billion. (source1)
- Estimate for number of stars in the universe is anywhere between 50 sextillion (source) to 300 sextillion (source). The total number of stars in the universe is greater than the total number of grains of sand on all the beaches of planet earth ! (source)
- A single star (our Sun) burns about 4 million tonnes of proton mass per second. Of this, only five pounds worth of energy is intercepted by the entire earth’s surface. That is a mere 0.00000008 percent of the total energy emitted by the Sun.
And, this whole show emerged from a tiny dot , 14 billion years ago ?
