The 2.7 million Kelvin photon temperature gives a typical photon energy of 250 electronvolt, thereby setting a typical mass scale for warm dark matter: particles much more massive than this, such as GeV–TeV mass WIMPs, would become non-relativistic much earlier than one year after the Big Bang and thus have FSLs much smaller than a ...
According to CERN, it has cost a few hundred million Swiss francs to produce about 1 billionth of a gram (the amount used so far for particle/antiparticle collisions). [84] In comparison, to produce the first atomic weapon, the cost of the Manhattan Project was estimated at $23 billion with inflation during 2007.
An antimatter weapon is a theoretically possible device using antimatter as a power source, a propellant, or an explosive for a weapon.Antimatter weapons are currently too costly and unreliable to be viable in warfare, as producing antimatter is enormously expensive (estimated at US$6 billion for every 100 nanograms), the quantities of antimatter generated are very small, and current ...

The gram as a unit may have it's difficulties, but they're not as bad as those of the kilogram. In exponential notation the gram is a much better unit to work with. Like the density of water is 1 gram/cubic cm or that the mass of the earth is 10E27.8 grams (approximately)and of the sun is 10E33.3 grams (approx.). And it fits well into the cgs ...
BERN (Reuters) - Switzerland said on Tuesday it was concerned by U.S. President-elect Donald Trump's proposals to raise tariffs and is considering how to respond if his new administration does so.
The city’s hated new congestion toll could dangerously delay FDNY response times — meaning the “difference between life and death,” unions repping thousands of Bravest warned Sunday. The ...
The density of dark matter in an expanding universe decreases more quickly than dark energy, and eventually the dark energy dominates. Specifically, when the volume of the universe doubles, the density of dark matter is halved, but the density of dark energy is nearly unchanged (it is exactly constant in the case of a cosmological constant).
