What role do supernovae play in the universe?
Scientists also have determined that supernovas play a key role in distributing elements throughout the universe. When the star explodes, it shoots elements and debris into space. These elements travel on to form new stars, planets and everything else in the universe.
How does dark energy affect the universe?
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. As a result, this form of energy would cause the universe to expand faster and faster.
Can we detect dark energy?
We can’t see dark energy. We can’t feel it or detect it in any way even with sophisticated scientific instruments. But most astronomers are convinced it exists because we can see its effects in the movement of galaxies.
Does dark matter give powers?
In the game series Mass Effect, dark matter is manifested in the form of a substance called “Element Zero”, which is informally referred to as “eezo”. The dark energy that eezo produces is harnessed to power FTL travel, and prenatal exposure to eezo is capable of giving humans telekinetic abilities.
What happens if a human touches dark matter?
We cannot measure it directly because we can’t touch it. We can only observe its existence by its gravitational effects on surrounding normal matter. So nothing would happen. Dark matter does not interact the electromagnetic force.
What if you were made of dark matter?
You’d become invisible, and your body wouldn’t appear as a collective whole, but your dark matter particles would still interact gravitationally. Trapped by the Earth’s gravity, those particles would start an endless marathon around the center of the Earth’s gravity — the core.
Where is the anti matter?
Antimatter may exist in relatively large amounts in far-away galaxies due to cosmic inflation in the primordial time of the universe.
Where did all the anti matter go?
Matter and antimatter annihilate each other on contact, and researchers believe such collisions destroyed almost all of the antimatter (and a large chunk of the matter) that initially existed in the cosmos.
What is the source of dark energy?
Dark energy is caused by energy inherent to the fabric of space itself, and as the Universe expands, it’s the energy density — the energy-per-unit-volume — that remains constant. As a result, a Universe filled with dark energy will see its expansion rate remain constant, rather than drop at all.
What’s the difference between antigravity and dark energy?
Dark matter produces an attractive force (gravity), while dark energy produces a repulsive force (antigravity). Together, they make up 96 percent of the universe—and we can’t see either. Astronomers know dark matter exists because visible matter doesn’t have enough gravitational muster to hold galaxies together.
Is dark energy vacuum energy?
One way to envisage the dark energy is that it seems to be linked to the vacuum of space. In other words it is an intrinsic property of the vacuum. So, the larger the volume of space, the more vacuum energy (dark energy) is present and the greater its effects.
Does dark matter interact with matter?
We know that dark matter exists, that it doesn’t interact significantly with itself, normal matter, or radiation, and that it’s cold.
