What is the estimated lifespan of the universe?
In 2018, the Planck Collaboration updated its estimate for the age of the universe to 13.787±0.020 billion years.
How do you calculate the age of the universe?
Astronomers estimate the age of the universe in two ways: 1) by looking for the oldest stars; and 2) by measuring the rate of expansion of the universe and extrapolating back to the Big Bang; just as crime detectives can trace the origin of a bullet from the holes in a wall.
What is the estimated size of the universe?
93 billion light-years
The radius of the observable universe is therefore estimated to be about 46.5 billion light-years and its diameter about 28.5 gigaparsecs (93 billion light-years, or 8.8×1026 metres or 2.89×1027 feet), which equals 880 yottametres.
How long is the lifespan of the universe?
General opinion, obviously unprovable, is 10 to the hundredth power. A number far beyond imagining. Originally Answered: What is the lifespan of our universe? According Vedic calculation current life of our universe is 150 trillion years and it’s total life span 300 trillion years.
What would happen if the universe stopped and collapsed?
According Vedic calculation current life of our universe is 150 trillion years and it’s total life span 300 trillion years. If a given amount of time stops and collapses would it be like a salmon and return to where it started, and if it does that in a large enough quantity would it deform physical space.
What is the origin of life in the universe?
It begins with the rate of star formation in the galaxy and the fraction of stars that have planets, leading step-by-step through the portion of planets that support life and – most speculatively – to the existence and durability of detectable, technological civilizations.
What is the temperature of the universe?
The measurable temperature of the universe today is about 2.73 kelvins (−270.42 °C; −454.76 °F), where as recently as several billion years ago, the temperature was closer to 5.08 kelvins. This observation was made using light passing through a gaseous galaxy.
