It is currently 2008...Since there was no Year Zero, it was 999997993 B.C. one billion years ago. Or, if you prefer the Long Scale (non-American) definition of a billion, it was 999999997993 B.C.
One billion seconds ago is roughly the equivalent of 31.7 years ago, using the US definition of one billion. One billion is one thousand millions.
In my opinion, I think the years were longer than they are now 2 billion years ago. No one will really ever know since there is no calendars that have been left behind from 2 billion years ago.
To calculate the number of years in one billion minutes, we need to divide one billion by the number of minutes in a year. There are 60 minutes in an hour, 24 hours in a day, and 365.25 days in a year (accounting for leap years). This gives us approximately 1901 years ago, so it would have been around the year 119 CE.
A.A billion seconds ago it was 1959.B.A billion minutes ago Jesus was alive.C.A billion hours ago our ancestors wereliving in the Stone Age.D.A billion days ago no-one walked on the earth on two feet.
One billion seconds equals about 31.68 years. 31.68 years ago in 1978, Jimmy Carter was president.
Who knows. It's a bit like asking how old someone is who lives in New Mexico. If we can see it and it's 13 billion light years away, then the only thing we know for sure is that it existed 13 billion years ago. If the whole galaxy suddenly winks out and disappears tomorrow, we won't know about it for another 13 billion years. For that matter, maybe it already has! +++ It's very simple. A light-year is the distance light travels in one year, so what you see of a galaxy 13 billion light-years away, is as it was 13 billion years ago. ' You'll have to live another 13 billions years to see it as it is "now"! :-)
* A tightly-packed stack of new $1,000 bills totaling $1 billion would be 63 miles high. In comparison, jet planes fly at 30,000 - 40,000 feet (5.7 - 7.7 miles high). * About a billion minutes ago, the Roman Empire was in full swing. (One billion minutes is about 1,900 years.) * About a billion hours ago, we were living in the Stone Age. (One billion hours is about 114,000 years.) * About a billion months ago, dinosaurs walked the earth. (One billion months is about 82 million years.) * A billion inches is 15,783 miles, more than halfway around the earth (circumference).
1000 years
Oxygen, for one thing.
Although one can argue whether or not Earth is actually 'alive', science shows that Earth is 4.6 billion years old.
The present best estimate is 4.6 billion years.
