When did light begin?
13 billion years ago
Why is dark matter so expensive?
Due to its explosive nature (it annihilates when in contact with normal matter) and energy-intensive production, the cost of making antimatter is astronomical. CERN produces about 1×10^15 antiprotons every year, but that only amounts to 1.67 nanograms.
Is Dark Matter dust?
“Dust”, the mysterious substance after which both trilogies are named, is based on a real scientific concept: dark matter. According to contemporary physics, roughly 85% of the mass in the universe consists of dark matter, but the stuff itself has never been observed. By growing up, people become connected to Dust.
Can I eat dark matter?
It won’t bind with anything you eat. If you eat it, it won’t stay inside you; it’ll drift away as though you weren’t there. Dark matter interacts barely, if at all, with ordinary matter except through gravity. You won’t find dark matter supplements in the store.
Was there dark matter before the Big Bang?
Using a new, simple mathematical framework, the study shows that dark matter may have been produced before the Big Bang during an era known as the cosmic inflation when space was expanding very rapidly. The rapid expansion is believed to lead to copious production of certain types of particles called scalars.
Does dark matter exist?
Dark matter, according to mathematical models, makes up three-quarters of all the matter in the universe. But it’s never been seen or fully explained. Now, an international team of scientists says it has found new evidence that perhaps dark matter doesn’t really exist after all.
Does dark matter create dark energy?
The particles account for about 85% of the matter in the universe and therefore their gravitational forces dominate the formation of large-scale structure. They have extended the ΛCDM model to allow dark matter to decay to create dark energy.
Does dark energy decay?
Dark energy decays as the scalar field rolls down its potential, consequently the current acceleration epoch is a transient. The second potential is the cosine, which can become negative as the field evolves, ensuring that a spatially flat universe collapses in the future.
How much is a gram of dark matter?
1 gram of dark matter is worth $65.5 trillion.
How much does dark matter cost?
It would be about 1 million trillion trillion dollars per ounce. The LUX experiment costed 10 million dollars to build.

How empty is space?
Outer space is not completely empty—it is a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium, as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays. Outer space does not begin at a definite altitude above the Earth’s surface.
Did the Big Bang create light?
During the first three minutes of the universe, the light elements were born during a process known as Big Bang nucleosynthesis. This set loose the initial flash of light created during the Big Bang, which is detectable today as cosmic microwave background radiation.
Could parallel universes exist?
Parallel universes may or may not exist; the case is unproved. We are going to have to live with that uncertainty. Nothing is wrong with scientifically based philosophical speculation, which is what multiverse proposals are. But we should name it for what it is.
