What are the different ways to create negative effective mass

[billllib]

Also can negative effective mass be used as a replacement in a warp drive? Also what is the most realistic warp drive theory?

Do you even know what "negative effective mass" is in band theory of solids? Your question appears to show a huge misconception of what it is.

I don't.

 

[ZapperZ]

I don't.

Then shouldn't you figure out what it is FIRST before trying to make speculative guesses on whether it may "... be used as a replacement in a warp drive ..."? It is nothing like what you think it is.

Sorry just one more question can dark energy be used in a warpdrive? I realize this might be a nonsensical question because we don't know what dark energy is exactly. Is dark energy negative mass? What is negative effective mass?

Before we go any further, you need to re-read the PF Rules that you had agreed to, especially regarding speculative posts, and then you need to read this:

Your obsession with negative effective mass and warp drive and such is not healthy, especially when you admittedly don't know what it is.
