Naw I wasn't agitated. Sorry if it came off that way because I definitely didn't intend it. I just love a good debate is all .
Wasn't sure... You
did seem agitated when I nitpicked about Occam's Razor. I will say this, though; all three provided phrases of Occam's Razor say essentially the same thing with no difference changing the ultimate meaning.
And yes, you pointing out the Schala pendant thing definitely helped. I completely overlooked that. So we are left with the observation that both Schala's pendant and dimensional travel appear to be important to reach the DBT except in the case of Schala's own travel to the DBT, which is unusual enough by nature that we can perhaps consider it an exception to the rule.
It should be noted that the MM is made of dreamstone like Schala's pendant and connects to a Lavos continuum.
And what do you mean by "special" gates? Do you mean a point at which the future is significantly altered such that by our reasoning a gate to the DBT should be created? The Gate at Lavos' arrival was likely created by the Entity for the purpose of Crono and co.'s use and probably didn't exist in the original timeline.
But if you mean "isn't Lavos' arrival a case where the timeline was sufficiently altered to create a gate to the DBT?" then I would say yes, Lavos' arrival would certainly qualify (as the future that Lavos obliterated was most likely that of the Reptite dimensions future). The fact that the party cannot access the DBT there is perhaps evidence against the hypothesis that Gates to the DBT appear only at sites of major timeline alteration - I would agree with that.
The latter. Not that I'm still playing devil's advocate, I was just unsure, as you mentioned, the gate was probably created by the Entity.
Which raises an interesting question - by our theory, where would a gate to the DBT actually appear? In Chrono Cross the site of the altered timeline was Opassa Beach, unambiguously. In Trigger the site of the altered timeline was the location in 1999 AD where Lavos was defeated, unambiguously. But what about Lavos' actual arrival and the extinction of the Reptite future? Would the gate appear at the location of Lavos' impact? Or out in space where some event caused Lavos to head towards earth? Or perhaps on the previous planet that Lavos was born on where some group of young alien time travellers failed to defeat his momma Lavos? It isn't clear.
Was there a gate at the site where Lavos was destroyed?..
Regarding the Lavos Gate, it might not exist in conventional space-time, as Lavos left the normal time continuum when he arrived. This is evidenced by Lavos' very quick disappearance after it's arrival and completion of its 'perfect being'(via absorption of the DNA of all of the planet's life) whether one fights Lavos in 12000BC or in 1999AD.
Ah! I just had an epiphany. When one goes to fight the Dream Devourer, one ends up in a 'room'(as in game area) with the standard Lavos Zone parallax used only for Lavos and those in his 'space'. However, as one proceeds further, one sees Magus[2] in front of a gate that leads directly to the DD. I move to say that said gate is the missing Reptite DBT gate. As per our theory, the gate needs an explanation.
Also, at the risk of being redundant, you missed my second question:
"Second, is not a gate that travels to a relative era different from a gate that leads to a specific space-time(e.g. Lucca gate or Day of Lavos Gate)?"
