I ' m a doctoral student taking part in a field campaign funded by you guessed it ! NASA in a few months . Have friends who work at Goddard and GISS who are now nervous as hell for the future of their positions . And all througout the campaign , all of my fellow members of academia and the scientific community wondered are we going to ever get coverage on climate change or even a single debate question ? The answer was no . And now here we are . Most of America doesn ' t even realize the how precarious is the position they now stand on . <| sep |> Who cares . It ' s your copy meaning it is identical . Say you have 1 array and you carbon copy it now you have 2 identical CC arrays , so you delete the first one , is the new one the same ? In computer memory its location will be new , however all the data will be the same so it makes it the same one . Only you hold the knowledge that it is a copy and not the original . Every night you sleep same thing happens . Technically the world does not exist for your consciousness .
