Okay, I know I have no business playing around with relativity, but things got heated and I grabbed this:
And turned it into:
Give it to me straight. Did I blow up the Earth?
That is a lot of energy! For example, if we converted 1kg of mass into energy and used it all to power a 100 watt light bulb how long could we keep it lit for? In order to answer the question the first thing to do is divide the result by watts (remember that 1 watt is 1 joule per second):
9 x 1016 J / 100W = 9 x 1014 seconds
That's a lot of seconds, but how long is that in years? A year (365.25 days) is 31,557,600 seconds, so:
9 x 1014 seconds / 31,557,600 seconds = 28,519,279 years
And turned it into:
At 100% efficiency, in order to create 1 kg of matter (about 2 lbs) you would need to consume 2.8 billion watts for a year.
Give it to me straight. Did I blow up the Earth?
