Dark matter pulls and dark energy pushes. That is, dark matter is invoked to explain greater-than-expected gravitational attraction. In contrast, dark energy is invoked to explain weaker-than-expected, and in fact negative, gravitational attraction.
Can we get super powers from dark matter if it exists? No and the reason to this this are many but here are a few. We have no evidence that “super powers” really exist. We know very little about dark matter so really can't say what it, or what might make it up, is capable of.
6 Answers. Energy is not made of anything, energy is a term used to describe a trait of matter and non-matter fields. When matter has velocity, for example, it is said to have kinetic energy. There are also various forms of potential energy.
Matter can be created and destroyed. In fact, matter is created and destroyed all the time. There is no one definition of matter but we can loosely define it as "anything composed of particles", including the particles themselves.
Dark matter can refer to any substance which interacts predominantly via gravity with visible matter (e.g., stars and planets). Hence in principle it need not be composed of a new type of fundamental particle but could, at least in part, be made up of standard baryonic matter, such as protons or neutrons.
The event horizon is where the escape speed exceeds the speed of light: you'd have to be going faster than light (which is impossible for any bit of matter) to escape the black hole's gravity. Inside the event horizon is where physics goes crazy. A singularity is what all the matter in a black hole gets crushed into.
Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA's Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter.
It would be about 1 million trillion trillion dollars per ounce. The LUX experiment costed 10 million dollars to build.
Understanding dark matter is important to understanding the size, shape and future of the universe. The amount of dark matter in the universe will determine if the universe is open (continues to expand), closed (expands to a point and then collapses) or flat (expands and then stops when it reaches equilibrium).
Thus, dark matter constitutes 85% of total mass, while dark energy plus dark matter constitute 95% of total mass–energy content. Because dark matter has not yet been observed directly, if it exists, it must barely interact with ordinary baryonic matter and radiation, except through gravity.
Energy. Scientists believe that almost all of your body's mass comes from the kinetic energy of the quarks and the binding energy of the gluons.
Primordial black holes are non-baryonic and as such are plausible dark matter candidates. Primordial black holes are also good candidates for being the seeds of the supermassive black holes at the center of massive galaxies, as well as of intermediate-mass black holes.
Yes. Although the names sound vague and almost fictional, the types of matter called antimatter, dark matter, dark energy, and degenerate matter are all different, specific entities that really exist in our universe.
In physical cosmology and astronomy, dark energy is an unknown form of energy that affects the universe on the largest scales. Prior to these observations, the only forms of matter-energy known to exist were ordinary matter, dark matter, and radiation.
Dark matter does not reveal its presence by emitting any type of electromagnetic radiation. It emits no infrared radiation, nor does it give off radio waves, ultraviolet radiation, X-rays or gamma rays. It is truly "dark." Cosmologists believe we can only see about 10 percent of the matter in the universe.
Named after Einstein's correction, it suggests that dark energy is the energy associated with the vacuum of space and has remained unchanged over the 14 billion years of the universe's history.
Composition. The universe is composed almost completely of dark energy, dark matter, and ordinary matter. Other contents are electromagnetic radiation (estimated to constitute from 0.005% to close to 0.01% of the total mass-energy of the universe) and antimatter.
In our own backyard, the Universe is full of stars. But go more than about 100,000 light years away, and you've left the Milky Way behind. Beyond that, there's a sea of galaxies: perhaps two trillion in total contained in our observable Universe.

Black is the darkest color, the result of the absence or complete absorption of visible light.
Generally, the outer darkness is thought to be hell; however, many Christians associate the outer darkness more generally as a place of separation from God or from the metaphorical "wedding banquet" that Jesus is expected to have upon his Second Coming.
Darkness, the polar opposite of brightness, is understood as a lack of illumination or an absence of visible light. Human vision is unable to distinguish color in conditions of either high brightness or high darkness.
The speed of sound through air is about 340 meters per second. It's faster through water, and it's even faster through steel. Light will travel through a vacuum at 300 million meters per second. No information can propagate faster than the speed of light.
The nature of dark energy is more hypothetical than that of dark matter, and many things about it remain in the realm of speculation. Dark energy is thought to be very homogeneous and not very dense, and is not known to interact through any of the fundamental forces other than gravity.
In terms of physics, an object is said to be dark when it absorbs photons, causing it to appear dim compared to other objects. A dark area has limited light sources, making things hard to see. Exposure to alternating light and darkness (night and day) has caused several evolutionary adaptations to darkness.
Darkness does not exist, there is only an absence of Light. Though these two facts may be true, our perception of the cold and darkness can be debilitating. But, we humans can withstand extreme cold with proper clothing and the belief of never ending darkness if we have hope that the sun will rise.
Darkness travels at the speed of light. More accurately, darkness does not exist by itself as a unique physical entity, but is simply the absence of light. Any time you block out most of the light – for instance, by cupping your hands together – you get darkness. And no light means darkness.
