Dark energy is the name given to the force that is believed to be making the universe larger. Distant galaxies appear to be moving away from us at high speed: the idea is that the universe is getting bigger and has been since the Big Bang.

How was dark energy discovered?
Dark energy was discovered in1998 by two teams of astronomers, who measured light coming from exploding stars called Type IA supernovae, known as “standard candles” for their consistent brightness. That was the first stand-alone evidence to support the idea of dark energy.

How do we know dark energy is there?
The curve changes noticeably about 7.5 billion years ago when objects in the universe began flying apart at a faster rate. Astronomers theorize that the faster expansion rate is due to a mysterious, dark force that is pulling galaxies apart. One explanation for dark energy is that it is a property of space.

Is dark energy powerful?
In brief, dark matter attracts, dark energy repels. While dark matter pulls matter inward, dark energy pushes it outward. Also, while dark energy shows itself only on the largest cosmic scale, dark matter exerts its influence on individual galaxies as well as the universe at large.

Is dark energy negative energy?
Dark energy is not negative energy. It causes a repulsion because of its unusual equation of state, which causes it to behave as if it has negative pressure. It’s not obvious that the energy of the universe or the gravitational potential energy of the universe is a well defined and useful concept.

Is dark energy everywhere?
Dark energy is everywhere – and when we say everywhere, we mean everywhere. It suffuses every corner of the cosmos, absolutely dominating everything in it. It dictates how the universe behaves now and how it will end.

Can we make dark matter?
Dark matter may be made of baryonic or non-baryonic matter. To hold the elements of the universe together, dark matter must make up approximately 80% percent of the universe. The missing matter could simply be more challenging to detect, made up of regular, baryonic matter.

Yes, it is very possible.

THE ATTACHMENT SYSTEM (termed “companionate love” in humans) is characterized in birds and mammals by behavior that may include defense of a mutual territory, mutual nest building, mutual feeding and grooming, separation anxiety, and shared parental chores.

In humans, attachment is also characterized by feelings of calm, security, social comfort, and emotional union. Attachment is associated in the brain primarily with the neuropeptides oxytocin and vasopressin. This emotion system evolved to motivate individuals to sustain their affiliations long enough to complete the impulse feeling of attraction towards their own species of the opposite sex.

For each system, the neural circuits can be expected to vary from one species to the next, among individuals within a species, and over the life of an individual. The three emotion systems also act in concert with one another and with other bodily systems.

For example, a person may begin a sexual liaison merely for sexual pleasure, then become romantically involved with this sexual partner. He can become deeply attached to this partner, too, and these enhanced feelings of attachment can be explained biologically.

Being in love triggers a cocktail of chemicals in the brain. Some of the hormones — which also act as neurotransmitters — that the body releases when we’re infatuated can have a soothing effect. These are the chemicals that cause the involuntary impulses that make one feel attracted to the other.
