Significant Figures and Scientific Notation
The age of the universe is believed to be approximately 14 billion years. Assuming two significant figures, write the age of the universe in (a) years and (b) seconds, in correct scientific notation.a) 1.4x1010 years
b) 1.4x1010 years * 365.24 days/year *1440 minutes/day * 60 seconds/minute
= 4.41794304x1017
However, we only have two significant figures (even though we used a number of numbers that have more significant figures – numbers like the seconds per minute have, by definition, an infinite number of significant figures, as there are exactly 60 seconds per minute.
= 4.4x1017 seconds

Using this age and total PLANK age so we found how next move of universe and found that body parameters of universe that it's able to hold life or we require some new baby universe as new baby universe are having more energy like new born baby have more mitochondrial activities which sustained life by providing more energy from less intake of food like a new universe have more energetic star system like mitochondrial activities of new born baby to sustain life by giving more energy by less intake of food🕉🕉🕉
