***So, if energy, matter and antimatter exist, shouldn’t anti-energy exist, at least conceptually? ***

That is an English argument- not a physics one.

***, I will venture that magnetism is nothing more than an amplified form of gravity. I say that what the laser does to light, putting it in phase - whereby its effects are amplified, the magnet does to gravity.

It is important to ask ourselves too, if we believe in a big bang scenario, why would we have electromagnetic waves in an early universe where no iron exists? ***

Here you go off the deep end. Magnetism cannot amplify gravity and electromagnetic waves do not need iron to exist, period.

The remaining discussion about gravity as anti-energy is correct and well known. It is exactly the potential energy argument I presented in the thread below.

One school of thought is that the universe has no net positive ot negative energy. The energy of the big bang came entirely from the negative potential or gravitational energy accrued from the expansion of space. So your idea of anti-energy is correct. But it does not apply to magnetism or iron.
