The amount of Martian deuterium (D/H = 9.3 ± 1.7 10 −4) is five to seven times the amount on Earth (D/H = 1.56 10 −4), suggesting that ancient Mars had significantly higher levels of water. Results from the Curiosity rover had previously found a high ratio of deuterium in Gale Crater , though not significantly high enough to suggest the ...

[35] [c] Thus this inscription anticipates the current universe lasting at least 20 21 ×13×360 days, [26] or roughly 2.687×10 28 years; a time span equal to 2 quintillion times the age of the universe as determined by cosmologists. Others have suggested that this date marks creation as having occurred after that time span.
