we would be living in a robotic world...........robots will occupy the humans work
A location that is 100 light years away from Earth.
The distance to a star located 100 light years away from Earth is 100 light years.
It would take 100 Earth years for a signal to travel from a star located 100 light years away to reach Earth.
Nobody knows the exactly the number of people who lived on earth in 100 years
Earth takes 1 year for 1 orbit around the sun. So, in 100 years, Earth can orbit the sun 100 times.
It would take 100 years for a signal to travel from Earth to a star located 100 light years away.
100 million years
100
about 100 years
Nope.... the Earth will still be nere in 100 years. HOWEVER - if we don't do something NOW to preserve and protect our planet from pollution, it will likely be uninhabitable in 100 years ! That said - our sun is estimated to only have about 6,000 years left before it expands to form a 'Red Giant' - at which time, the Earth will be a lifeless, charred cinder !
There is no way to know.
How long have turtles been on the Earth? They have been around for 300 million years.
