According to some interpretations of quantum field theory, or QFT, the fundamental state of matter isn't particles but fields instead. What we could call a particle is merely a local excitation of a field, or of a few fields that interact with each other.
This requires that the universe be comprised of fields that can have different local levels of energy. It also implies that the universe is permeated in non-zero levels of energy, because any point in the universe that can contain energy isn't empty.
In physics there is a distinction between a vacuum and a void. A vacuum is the absence of particles, or with a QFT interpretation the absence of local excitations of fields, whereas a void is the absence of energy. A vacuum is not a void, as it holds what we call Zero Point Energy.
This Zero Point Energy is just the resting state of a non-excited field. If you were to add energy to this field you would have something that looks like a particle of that field's type. A photon in an electromagnetic field, an electron in an electron field, etc. These fields can interact with each other, an electron can absorb and later emit a photon.
I suggest that instead of viewing it as a collision of atoms, you interpret the teleportation process as being additive. Each of the fields and their energy levels in the mountain ranges suddenly gain the amounts of energy contained within the steel sphere.
This would have a number of incalculable consequences. The simplest solution would be to say that the energy that was added is immediately expelled from the system due to it no longer being stable in the context of another field already containing different energy levels. 800
So all of the energy being added is forced to spread out evenly in the surrounding space. Which is just a very odd way of describing an explosion. Just how big of an explosion would it be though?
The composition of steel is variable but let's say it's 99% iron and therefore has a density of nearly 7 874 kg/m³. A 1 meter diameter sphere has a volume of V = 4 ⁄ 3 × π × R³ = 4 ⁄ 3 × π × 0.5³ = 0.52 m³. So that's a total of 7 874 × 0.52 = 4 095 kg of iron atoms. To calculate the energy contained in 4 095 kg of iron we can apply the famous E = mc² E = 4 095 × (3 × 10^8)² = 3.68^20 J = 0.36 Zettajoule
It's almost the equivalent of the entire world's energy consumption in 2010. For comparison to something we have more direct evidence of the destructive effects of, the atomic bomb that annihilated Hiroshima had an energy yield of a few Terajoules (10^12 J).
In fact it's such a massive amount of energy that it's over 250 times the 2011 earthquake and tsunami in Japan(https://en.wikipedia.org/wiki/Joule#Multiples).
Of course, a non-violent alternative is to imagine that the effects of adding energy to a field changes the composition of the elements we can observe, and transmutes the mountain into various other elements higher up in the periodic table. So instead of rock composed of oxygen and silicon you might have a mix of zirconium and molybdenum. This type of effect, if discovered, could lead to the birth of a transmutation industry. Perhaps it should be destroyed to protect the economy, or used in secret to the profit of a few. 921
