37.8 Ym – 4 billion light-years – length of the Huge-LQG; 75 Ym – redshift 0.95 – 8 billion light-years – approximate distance to the supernova SN 2002dd in the Hubble Deep Field North (light travel distance) 85 Ym – redshift 1.6 – 9 billion light-years – approximate distance to the gamma-ray burst GRB 990123 (light travel distance)
(1 000 000 000 000 000; 1000 5; short scale: one quadrillion; long scale: one thousand billion, or one billiard) ISO: peta- (P) Biology – Insects : 1,000,000,000,000,000 to 10,000,000,000,000,000 (10 15 to 10 16 ) – The estimated total number of ants on Earth alive at any one time (their biomass is approximately equal to the total biomass ...
For instance, according to the prevailing Big Bang model, our universe is approximately 13.8 billion years old (equivalent to 4.355 × 10 17 seconds). The observable universe spans an incredible 93 billion light years (approximately 8.8 × 10 26 meters) and hosts around 5 × 10 22 stars, organized into roughly 125 billion galaxies (as observed ...

List of orders of magnitude for energy; Factor (joules) SI prefix Value Item 10 −34: 6.626 × 10 −34 J: Energy of a photon with a frequency of 1 hertz. [1]8 × 10 −34 J: Average kinetic energy of translational motion of a molecule at the lowest temperature reached (38 picokelvin [2] as of 2021)
2.8 billion Earth's surface temperature will reach around 420 K (147 °C; 296 °F), even at the poles. [80] [96] 2.8 billion High estimate until all remaining Earth life goes extinct. [80] [96] 3–4 billion The Earth's core freezes if the inner core continues to grow in size, based on its current growth rate of 1 mm (0.039 in) in diameter per ...
Graham's number is an immense number that arose as an upper bound on the answer of a problem in the mathematical field of Ramsey theory.It is much larger than many other large numbers such as Skewes's number and Moser's number, both of which are in turn much larger than a googolplex.
One part per quadrillion (ppq) denotes one part per 1,000,000,000,000,000 (10 15) parts, and a value of 10 −15. This is equivalent to about two and a half minutes out of the age of the Earth (4.5 billion years).
