Still makes it porous.

The accretion of material from space is on the order of a centimeter a billion years. It is ludicrous to claim this increases the pressure in the interior of the Earth. The interior heat of the Earth is not due to the accumulation of materials from space. Also, the mantle is not liquid. There simply is no evidence for expansion.
Th expanding Earth isn't exactly a completely worked out theory, but it does make a lot more sense than the idea of one crustal plate being forced down under another, piercing into the much more dense mantle.
Not a worked out theory? It is one of the STUPIDEST ideas proposed yet. Nothing about it makes sense. Here you are claiming that the accretion causes expansion when that is obviously nonsense. The accumulation is marginal. Please show us how the increased mass would provide enough energy for thermal expansion. Obviously it cannot.
If Plate Tectonics theory is so complete, please explain this problem. How is the Pacific ocean being shrunk, when all evidence points to the Pacific Ocean expanding?
Measurements show it is not increasing.
The theory still needs development, but already it is more complete than the concept of tectonic plate drift.
The idea was trashed a long time ago, but it keeps coming up like flat earth, and 2012. It is simply a failed idea.
There is a type of plasma called "dirty plasma" which could be adding matter to the core, or mantle
...since I believe they are setting the vertical movement to zero...
Possibly, the pressure of the water, would help to contain the expansion to a certain level until an extremely active seismic cycle occurred, creating a tipping point where the expansion occurs rapidly and violently, which could be cyclical.
This could be why we are seeing an uptick in volcano and earthquake activity.
Since the earth is 70% water, and less than 5% (or less) of the ocean floor has been explored, I think even a pretty large expansion might go unnoticed.
That would mean the major part of the expansion would be under water, which would actually raise the level of the water, as you can see if you do an experiment such as taking a bowl and putting some water in it. Empty the bowl, put a rock in it, and then put the same amount of water in it. What do you see? The level of the water goes up, because the rock has displaced some of the water.
If plasma comes from the sun, and water has been found on the sun, and water can be broken apart to create plasma, it's seems like it would be possible to convert plasma into water. Perhaps that's where all the water on the earth originally came from.

To clarify, the Earth's surface is 70% covered by water. The ocean floor is well mapped by satellites. The maps are not in great detail, but the structures are known.
my statement:

This is very wrong. The water level should drop since the volume of the bowl increases and the water volume is constant.

I thought all rocks have a measurable amount of porosity, granite being less than most but with some types of granite more porous than others. A case in point, a town near me recently had a facelift of the main street and promenade using granite imported from China. Some areas of the granite have become badly stained as they absorb pollutants. They left the original kerbs which are of local Mourne granite which is a much denser and darker material and does not have a staining problem.
Not all of the floor is mapped, what has been, is in very poor detail, and very little at deep levels has been studied in depth, because of the enormous constraints in being able to do so. More is known about the surface of the moon than the bottom of the ocean. (I looked this up and read various scientific commentaries that stated this.)
This statement by you above, **** which is very, very, VERY wrong ****, is enough to make me discount EVERYTHING you have said in this thread.
The volume of the bowl DOES NOT increase, it stays the same, but you are adding something (matter) to the bowl which takes up space and actually decreases the amount the bowl will hold.
I KNEW MY EXPERIMENT SUGGESTED ABOVE WAS CORRECT. AND I JUST CONFIRMED IT BY ACTUALLY DOING IT.
Did you even try it yourself, before you said it was wrong?
Just like the *continental drift theory* was ridiculed and then gradually accepted, and then gradually parts of that theory was replaced by *plate tectonics /subduction zones* which seemed to fit better.
If you think about it, some parts of the *expansion theory* pretty well describes *plate tectonics /subduction zones* end result or actions.
Obviously, if it can be stained, or out gasses radon, and has to be SEALED, it must be porous.

Earthquakes are surface events. The energy may be transferred through the planet via P and S waves, but the effect does not rip the planet apart. Gravity keeps the planet together. Nothing can escape the planet or rip ir apart unless parts reach escape velocity.
Planet X does not exist within the orbits of the known planets. That is demonstrable. Any unknown planet must be very far away. Even an Earth sized object would have to be beyond the Kuiper belt and never enter the orbits of the known planets.

Staining is often a surface event. Sealing is to seal small cracks. The cracks are due to the granite shrinking.
The only reason anyone is claiming that granite is porous is to try and attempt to shore up the notion that pore spaces allow the Earth to increase in volume without adding matter. There is no way that the minor pore space in granite can double the size of the Earth.
The pore issue is nonsense when it comes to shoring up the failed expanding earth tale.
It is also (surprisingly) being suggested to be a relatively short process, for the most part....on the order of a few hundred million years.
