anyway to prevent this from going adrift back to an earlier point:can you imagine what it would mean if the anomalous spectrum reading from Perseus and Andromeda turns out to be from matter with nonstandard nucleons or an electron substitute of some type?the strength of electronic bonds and nuclear bonds in matter are derived in part from the density and mass of the nucleons and the bond lengths of the electrons. if you had carbon and iron that had smaller nucleons and tighter bonding orbitals then steel made from these exotic atoms would have magnified properties. it would be harder to break the bonds. photons and particles would have a tougher time going through the atoms and empty spaces between atoms. it would have a higher melting point. it would be harder to break, bend, puncture, or cut.you could have hull materials that could take a beating, shield from radiation better and could reenter the atmosphere unphased or go beyond current limits of crush depth in the ocean or in dense atmospheres like venus.if there was not a fault in the machine or an error in the signal processing then whatever that was it was not a known element and there is almost no room in the periodic table for unknown normal matter elements. on the face of it it is something other than known forms of matter.
The theoretical framework for the experiments dates back to work by Harold G. White from 2003 as well as work by White and Eric W. Davis from 2006 that was published in the AIP, where they also consider how baryonic matter could, at least mathematically, adopt characteristics of dark energy (see section below). In the process, they described how a toroidal positive energy density may result in a spherical negative-pressure region, possibly eliminating the need for actual exotic matter.[2][4]
Dark matter may not be made of tiny particles as most scientists believe, but instead may consist of large chunks of strange matter anywhere from the size of an apple to an asteroid, researchers said.
Dunno what that was all about...
I have no idea if there is such a thing as "negative energy". However, such a concept cannot be created at all, even with a well produced video complete with wooshing sounds, eery music, a narrator with a well modulated voice, and an artificially dirty actor pretending to dig a hole from pre-loosened soil.
But curious, at least for me it takes energy to dig a hole in a field. Would energy required to dig a hole big enough to fit an universe be positive, negative, neutral or is it some sort of self-digging hole?

I've felt negative energy while trying to dig a trench in muddy field to drain a puddle suffocating crops. Hammering finger instead of nail creates sudden strong negative energy. There's a lot of negative energy in internet forums too!But curious, at least for me it takes energy to dig a hole in a field.

If you read this paper:http://adsabs.harvard.edu/abs/2010arXiv1005.5682MYou’ll see that “exotic matter” is actually “negative space-time pressure.”The Cassimir Effect, which Dr White is focusing on, goes like this:1) Make a metal donut.2) Run a ridiculous amount of electricity into it.3) Space-time should expand at the center of the donut, or, if you blast enough electricity, around the donut.This space-time expansion (also called an increase in York Time) IS exotic matter. In other words, physicists have a weird name for the expansion of space-time.The question is how much energy will it actually require to achieve this expansion. The current experiments focus on determining whether the Cassimir Effect even works as we’ve theorized, and then how much energy delivers how much expansion.
Please don't hate or call me stupid im just wondering is it how that works, if anyone knows answers or any explanation for me thanks
this is rather old but it is an article at Icarus in which Dr White participates in the comment section. someone other than Dr White had the following to say:http://www.icarusinterstellar.org/daydreaming-beyond-the-solar-system-with-warp-field-mechanics/QuoteIf you read this paper:http://adsabs.harvard.edu/abs/2010arXiv1005.5682MYou’ll see that “exotic matter” is actually “negative space-time pressure.”The Cassimir Effect, which Dr White is focusing on, goes like this:1) Make a metal donut.2) Run a ridiculous amount of electricity into it.3) Space-time should expand at the center of the donut, or, if you blast enough electricity, around the donut.This space-time expansion (also called an increase in York Time) IS exotic matter.

for certain spatial models negative energy may not be necessary according to this wikipedia article:http://en.wikipedia.org/wiki/Warp-field_experimentsin the first paragraph towards the bottom:QuoteThe theoretical framework for the experiments dates back to work by Harold G. White from 2003 as well as work by White and Eric W. Davis from 2006 that was published in the AIP, where they also consider how baryonic matter could, at least mathematically, adopt characteristics of dark energy (see section below).

Propellant-less Propulsion:Negative effective mass = Negative energy is negative work. You want to separate these so that negative work is in front of the apparatus and positive work is done behind the apparatus. Similar to how positive energy should attract but negative energy should repel. Line them up and it starts drifting froward. How to you avoid the infinite energy conundrum from constant acceleration? You have to do work so entropy increases. What would you be pushing against if not the light itself? It might transfer energy to the vacuum efficiently and make gravity waves. Yes the vacuum can flow. (Lense-Thirring effect) https://en.wikipedia.org/wiki/Lense%E2%80%93Thirring_precessionWe already have a working example of propellant-less propulsion. A phased array is a form of propellant-less propulsion. Problem is in a phased array we have 2 forces working against each other. Static electric vs magnetic. There is a way to rectify this and I think it would give larger than photon propulsion but the way things are going I question if I will ever have the chance to build it. https://forum.nasaspaceflight.com/index.php?topic=36911.msg1459290#msg1459290-rant- But hey, I suppose capitalism is all that and a bag of chips they say. Mean while I know for a fact car companies could be making cars capable of hundreds of miles/gallon, but they work and go vroom vroom. Good enough eh? Frog in the pot comes to mind. -song- it's a small world after all. /song -/rant-
