[8] [9] [10] The latter spelling is still listed in some dictionaries, [1] but is now rare in English texts. Some popular US dictionaries list only the spelling angstrom. [2] [3] The unit's symbol is Å, which is a letter of the Swedish alphabet, regardless of how the unit is spelled.
2.6 × 10 11 Qs (8.2 × 10 33 years): The smallest possible value for proton half-life consistent with experiment [19] 10 23 Qs ( 3.2 × 10 45 years ): The largest possible value for the proton half-life , assuming that the Big Bang was inflationary and that the same process that made baryons predominate over antibaryons in the early Universe ...

Order of magnitude is a concept used to discuss the scale of numbers in relation to one another. Two numbers are "within an order of magnitude" of each other if their ratio is between 1/10 and 10. In other words, the two numbers are within about a factor of 10 of each other. [1] For example, 1 and 1.02 are within an order of magnitude. So are 1 ...
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)
Astronomers have detected one of the most distant and energetic mysterious fast radio bursts in space, a millisecond-long blast of radio waves that traveled 8 billion years to reach Earth.
Astronomers detected a fast radio burst from a galaxy 8 billion light-years away. It's a new record, and the signal's source is still a mystery. Scientists detect 8 billion-year-old radio burst.
In number theory, a narcissistic number [1] [2] (also known as a pluperfect digital invariant (PPDI), [3] an Armstrong number [4] (after Michael F. Armstrong) [5] or a plus perfect number) [6] in a given number base is a number that is the sum of its own digits each raised to the power of the number of digits.
