If it is the rough estimation, then only the first three non-zero digits are significant since the trailing zeros are neither reliable nor necessary; 45600 m can be expressed as 45.6 km or as 4.56 × 10 4 m in scientific notation, and neither expression requires the trailing zeros. An exact number has an infinite number of significant figures.

The Big Bang explains the evolution of the universe from a starting density and temperature that is well beyond humanity's capability to replicate, so extrapolations to the most extreme conditions and earliest times are necessarily more speculative. Lemaître called this initial state the "primeval atom" while Gamow called the material "ylem ...
A 2023 study shows evidence, based on the orbital inclination of Deimos (a small moon of Mars), that Mars may once have had a ring system 3.5 billion years to 4 billion years ago. [32] This ring system may have been formed from a moon, 20 times more massive than Phobos , orbiting Mars billions of years ago; and Phobos would be a remnant of that ...
A neutrino (/ nj uː ˈ t r iː n oʊ / new-TREE-noh; denoted by the Greek letter ν) is an elementary particle that interacts via the weak interaction and gravity. [2] [3] The neutrino is so named because it is electrically neutral and because its rest mass is so small that it was long thought to be zero.
A previous format, called "IPv4-compatible IPv6 address", was ::192.0.2.128; however, this method is deprecated. [ 36 ] Because of the significant internal differences between IPv4 and IPv6 protocol stacks, some of the lower-level functionality available to programmers in the IPv6 stack does not work the same when used with IPv4-mapped addresses.
The South Korean won (Symbol: ₩; Code: KRW; Korean: 대한민국 원) is the official currency of South Korea.A single won is divided into 100 jeon, the monetary subunit.
Tendulkar was again out of the first three ODIs of a seven-match ODI series at home against England due to an injury, but he made 11 in the fourth ODI [202] and 50 in the fifth, [203] before the series was called off due to the 2008 Mumbai terrorist attacks, the scoreline being 5–0 to India.
