Re: Another fan attempt at TOS deck plans


I actually like (and very much enjoyed) Enterprise, and liked their recreation of the Defiant. But for the most part, I'm mainly exploring whether or not Jefferies' views of this during the pilots and original run of the series works out nicely or not.

I, obviously, have my own theories on lots of this stuff... but I'm trying to keep those some what separate from what I'm attempting here.

As I understand it gravity is a product of mass.
Gravity is an accelerated reference frame. So as long as you are in a reference frame of constant acceleration, you'll experience gravity... with all the relativistic effects one would associate with that magnitude of gravity.

The foundations of Einstein's General Theory of Relativity are based on thought experiments about what really is gravity. If you were in a room in the middle of nowhere, no large bodies near by, and the room was accelerating at a constant 9.8 meters per second per second, there is no experiment you could do within that room to differentiate between the gravitational effect of a planet like the Earth or the constant acceleration of the room in empty space.

Mass happens to distort space-time near sufficiently large bodies to give those regions the characteristics of an accelerated frame of reference. And the accelerated frame of reference is really our only experience with gravity, and would be the only thing needed to be replicated for artificial gravity.

What is often overlooked is that General Relativity wasn't just a theory of gravity, it was intended to fill in the (rather large) holes left open by Special Relativity (which only works for reference frames of constant velocity... something that doesn't really happen much in the real world, hence the Special part of the name).

I love the subject of gravity, and it was the attractive force ( ) that pulled me first into physics and finally into mathematics (because physics programs do an awful job teaching the differential geometry and differential topology needed for a truly deep study of the subject... sorry for the rant about physics programs ).
