If Earth was converted into energy by antimatter-matter collision would the energy "destroy" the observable universe?
If half the earth was made antimatter and contacted the other half all at once, would the resulting energy be enough to "destroy" the observable universe?
I did some math based on the mass of the earth being around 5*10^24kg and an antimatter explosion given a mass of 1kg being about 43 megatons, and a nuclear explosion with a 4 megaton load leaving a fireball with a 1 mile radius. So that would be 1kg of antimatter and matter = about 10 mile radius and 5*10^24kg of antimatter = 5*10^25 miles radius where as the observable universe of 13.8 billion light years can be converted to 8*10^22 miles < 5*10^25 miles. Is this accurate?
