"The catch is that traversable wormholes require negative energy. Because negative energy is gravitationally repulsive, it would prevent the wormhole from collapsing."
"Negative energy is so strange that one might think it must violate some law of physics."

"a portal through space created by energy fluctuations in positive and negative directions. The different fluctuations would each create a curved space that opposes the other. If these two were then connected, you would have a wormhole. If it lasted long enough, theoretically a particle could be transported through."

"Einstein couldn't keep a wormhole open because all the matter and energy he knew of was positive, and so according to his theory could only work one way.
Exotic matter is matter that is different in this key respect: it violates certain so-called "energy conditions" in general relativity that matter generally shouldn't.
In particular, it must appear for at least some observers to have negative energy. This is how it stops a wormhole from collapsing: whereas ordinary matter attracts, exotic matter repels, or more accurately in general relativity it causes spacetime to curve "in the opposite way" and so opposes the natural tendency of a wormhole throat to pull in on itself according to the equations of general relativity."

"The amount of sunlight that strikes the earth's surface in an hour and a half is enough to handle the entire world's energy consumption for a full year."
"This energy can be used to generate electricity or be stored in batteries or thermal storage."
"This energy creates electrical charges"

"it all starts deep inside Earth. As electrically charged, molten iron churns far below Earth’s surface, within the planet’s outer core, it generates a magnetic field large enough to extend far out into space."

"Stick an antenna up in the air, the higher the better, and wire it to one side of a capacitor, the other going to a good earth ground, and the potential difference will then charge the capacitor."

"One either has to harness the power of a star, or to find something called “exotic” matter (which falls up, rather than down) or find a source of negative energy."

"Beyond gases, there’s another state of matter called plasma. And it makes up 99.9% of the observable universe."
"a plasma is made up of atoms or molecules that have been excited with energy. Those atoms are made of three different particles - neutrons, protons and electrons."
"Electric and magnetic fields are all around us, but they don't typically affect solids, liquids, and gases we interact with. They do shape plasma."
"So it turns out that almost everything in our universe above an atmosphere altitude of about 100 kilometers, is a plasma. Some people estimate that 99.9% of everything in the universe is a plasma."
"You have to remember that space is really big, and so much of our universe isn’t made up of planets or stars but is the really really vast spaces in between those objects.
HOST PADI BOYD: Most of interstellar space - the distances between solar systems - is full of hydrogen and helium plasmas. These interstellar plasmas are the result of exploded giant stars, millions of years ago. Overall, plasmas make up more matter than all of the solids, liquids, and gases in our universe combined."

"Physicists now suggest that spacetime may itself be a fluid, a very slippery type known as a superfluid.
These new findings could help scientists in their quest for a theory of everything that explains how the cosmos works in its entirety."
