The concept of dark matter involves a physical objects' internal quantum vibration exeding "cresendo point" which is 186,000 mps. Once you can achive that (it is possible by means of coherance and charge) the same vibrational framework allowing it to stay mateialized in our 3 dimensional reality spacetime, becomes inverted, resulting in de-materialization. Were does the matter go? If your talking about inversion, than you know that if you leave space-time, you end up in time-space. The matter itself will never go away. ever. Were we are now (spacetime) you have 3 dimensions of space, while time is a constant (1D), of course. Once again since inversion has occured, timespace allows 3 dimensional time (awsome!) while space is the constant. This is not crackpot science, as this occures on a daily basis in the bermuda triangle, as well as ancient egypt.
