Could We Make Artificial Gravity?

Like the Higgs Boson who walked into church and said you can't have Mass without me! (Bada-bump)

Along those lines, scientists recently produced an artificial vacuum. Unfortunately, it sucked.

I defied a Newtonian Law once.

The judge gave me ninety days.

Mass or acceleration (spinning works). No other way to create gravity.

An argument has been made that gravity is virtual, not a thing in itself, but an effect caused by the curvature of space by mass.

To start with, under many circumstances, time and space seem to be two dimensions of the same thing. Change one and you change the other. And if you are familiar with Einstein’s two dimensional grid model of space, you know that mass acts upon space by deforming it, also deforming time in the process.

The hard part, much more difficult to conceptualize, is that the grid is actually three dimensional, so bodies with mass deform space all around it, towards it. And this deformation of space and time is such that it seems to do what gravity does, but without the need for gravity.

In any event, this perhaps makes creating “artificial gravity” easier, because instead of manipulating gravity, you manipulate space time like mass does.

True but there is a beauty to the ring.

Some of the best. Firefly, if allowed to live may have become a rival.

Gravity has no speed limit, and in space there is no speed limit that we know of.
To accelerate in space at 1g would be a waste of time because if gravity
can be artificially produced speed has no boundaries in space. Light is also
effected by gravity which shows how powerful it is, and constant.

Gravity from one million light years away effects us, so imagine traveling on
a wave of gravity to anywhere at any speed. Watch out for that one speck of
dust at high speeds though, one particle and it's curtains.
