Scientists have long tried to explain the origin of a mysterious, large and anomalously cold region of the sky. In 2015, they came close to figuring it out as a study showed it to be a “supervoid” in which the density of galaxies is much lower than it is in the rest of the universe. However, other studies haven’t managed to replicate the result.
Low energy efficiency is already a major problem for petrol and diesel vehicles. Typically, only 20% of the overall well-to-wheel energy is actually used to power these vehicles. The other 80% is lost through oil extraction, refinement, transport, evaporation, and engine heat. This low energy efficiency is the primary reason why fossil fuel vehicles are emissions-intensive, and relatively expensive to run.
In the upcoming 50 years, humankind will attempt to answer fundamental questions about the universe and the fundamentals of our existence: Is there life on exoplanets? Is there extraterrestrial life in our solar system? Where has all the antimatter in the universe gone? - Robin Smith explains what we can expect
Quantum computing is an amazingly interesting field. Many predict that quantum computers will dominate our future. Nevertheless, there are also some inherent flaws in quantum computer hardware. Subhash Kak predicts that random errors resulting from those flaws might mean that quantum computers will be less useful than we expect them to be..
