How does the amount of energy in the univeres today compare to the amount in the universe one million ago?
It isn't entirely clear whether total energy is conserved in General Relativity, or whether the total energy is even clearly defined in all cases. But in general it is assumed that the total amount of energy doesn't change over time.
Why do astronomers theorize that there is dark energy in the universe?
There are several pieces of evidence for dark matter. For example: * Our galaxy, and many other galaxies, rotate way too fast for the amount of known matter. * Evidence from gravitational lensing.
What is the largest source of potential energy in the universe?
Hydrogen .
Which is thought to be more prevalent in the universe dark matter or dark energy?
Dark energy. The current estimates for the distribution of mass/energy in the Universe are approximately: 68% dark energy 27% dark matter 5% baryonic (i.e. "normal") matter
What do scientist use to explain the expanding universe?
Dark energy.
Why does the amount of energy in the universe never changes?
The total amount of energy in the universe remains constant because of the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or converted from one form to another. This means that while energy may change from one form (such as kinetic energy to potential energy) or be transferred between objects, the total amount of energy in the universe remains constant.
What does the total amount of energy and mass equivalent energy in the universe never do?
The total energy and mass-energy equivalent in the universe remains constant. This principle is known as the conservation of energy and mass-energy equivalence, as stated by the law of conservation of energy in physics.
The amount of energy in the universe is?
The Total amount of energy in the universe is E=mc2 =1.9 E70 Joules.
The total amount of energy in the universes eye?
The total amount of energy in the universe eye is zero.
What is the total amount of energy in the universe?
The total amount of energy in the universe is not precisely known, but it is believed to be constant due to the law of conservation of energy. This energy exists in various forms, such as light, heat, and matter, and is constantly changing and transforming within the universe.
Is there a finite amount of energy in the universe?
Yes, according to the law of conservation of energy, energy cannot be created or destroyed, only transferred or converted. Therefore, the total amount of energy in the universe remains constant.
True or false The study of the flow and transformation of energy in the universe is called energy dynamics?
False. The study of the flow and transformation of energy in the universe is called thermodynamics. Energy dynamics typically refers to the study of how energy moves and changes within a specific system or process.
According to the law of conservation of energy the total amount of energy in the universe?
true
What is the total amount of energy that changes?
If it is mechanical energy, that is called "work". For thermal energy, the word "heat" is used. For energy in general, I don't think there is a special name for it.
When potential energy changes to kinetic energy it is called?
When potential energy changes to kinetic energy, it is called energy transformation.
How much energy is there in the universe and what implications does this vast amount of energy have on the nature of the cosmos?
The total energy in the universe is not precisely known, but it is believed to be immense. This vast amount of energy has significant implications on the nature of the cosmos, influencing the expansion of the universe, the formation of galaxies and stars, and the existence of dark matter and dark energy. The energy in the universe plays a crucial role in shaping the structure and evolution of the cosmos.
The law which states that the total amount of energy in the universe does not change?
The Law of Conservation of Energy
