Net energy of the universe
WebJan 14, 2009 · The Earth’s climate is a solar powered system. Globally, over the course of the year, the Earth system—land surfaces, oceans, and atmosphere—absorbs an average of about 240 watts of solar power per square meter (one watt is one joule of energy every second). The absorbed sunlight drives photosynthesis, fuels evaporation, melts snow and ... WebSep 29, 2024 · The remaining 68.5 percent is dark energy. "To put that amount of matter in context, if all the matter in the Universe were spread out evenly across space, it would correspond to an average mass density equal to only about six hydrogen atoms per cubic meter," said astronomer Mohamed Abdullah of the University of California, Riverside and …

Light, matter and antimatter are what physicists call \"positive energy.\" And yes, there's a lot of it (though no one is sure quite how much). Most physicists think, however, that there is an equal amount of \"negative energy\" stored in the gravitational attraction that exists between all the positive-energy … See more Stephen Hawking explains the concept of negative energy in his book The Theory of Everything (New Millennium 2002): \"Two pieces of matter that are close to each other have less [positive] energy than the same two pieces a … See more The question, then, is why the ball started falling in the first place. How did something composed of equal positive and negative parts, mind you come from nothing? See more The universe as a whole can be compared to this ball. Initially, before the big bang, the universe-ball was at rest. Now, after the big bang, it is falling: light and matter exist, and they are moving. And yet, because of the … See more Physicists aren't exactly sure, but their best guess is that the extreme positive and negative quantities of energy randomly fluctuated into existence. \"Quantum theory, and … See more WebAbstract: In this paper we examine homogeneous and anisotropic Bianchi type-V universe filled with interacting Dark matter and Holographic dark energy.
