If one assumes that the universe was created from a single batch of energy or a single batch of mass, then an integration over the entire universe of both energy and mass would yield a constant. However integration over apart of the universe for a given time or space interval would yield a changing of both. For instance our sun is always losing energy, as Hydrogen is converted to helium in the Fusion process. This process result in a loss of mass for the sun. But it has plenty to go. Take another section of the universe and you would see a gain in mass as cosmic particles accumulate due to gravitational attraction. I recall presenting this idea of a constant energy/mass to my Physics professor long ago. He felt it was an oversimplification of the universe for which much is unknown. He admired my thinking process though, as so many problems in Physics are solved using conservation theories. Still, look at early models of the atom and how they explained processes without actual sight, as with the Bohr model. Many changes have been added since, but no one really knows. And what about dark matter. A fantastic field Physics is!

Yes, the amount of mass can change over time due to various processes such as chemical reactions, nuclear reactions, or simply by gaining or losing material from the surrounding environment. This change in mass is governed by the conservation of mass principle, which states that mass cannot be created or destroyed, only transformed into different forms.

Why is it better to use percent change in mass rather than change in mass when analyzing the data?
A percent change in mass is expressed more often than a variable change of mass in order to establish a coordinate for comparison. Your question about why it is better is a bit like asking why do we use specific traffic signs to indicate different driving functions. It is a matter of taste for efficiency purposes. Mass is related to acceleration and it would complicate our preferences to have to think about that all the time.
Will the time period of loaded spring change when taken to moon?
No, the time period of a loaded spring will not change when taken to the moon. The time period of a spring-mass system depends on the mass of the object attached to the spring and the spring constant, both of which remain constant regardless of the location.
How will the mass of a rocket change when it has reached outer space?
NO. the rocket will not shrink,grow,compact,or spread out and stay same size.the stuff in it will stay the same,,,,,,,,,,but the weight will change because there is no gravity to pull down on it. (The mass of the rocket will change continuously from the time it leaves the launch pad until sometime after it has reached space. That's because of the fuel mass it loses, as the engines burn. But once the engines cut off, the vehicle's mass doesn't change.)
Bright explosions of hot gases from the chromosphere are called?
Solar flares. They can release a massive amount of energy in a short amount of time, and can cause disruptions to communication systems and power grids on Earth.
When does the moon change shape?
The moon supposedly "changes shape" all the time, as the moon is constantly orbiting the Earth however the moon doesn't actually change shape, it is the amount of the sunlit side of the Earth that we see changing.
Why can't you change the total amount of mass in an object?
Who said you can't do that ? ? You change your own total mass every time you eat breakfast.
What is law conservation of massmatter?
Conservation of mass. It means that in a closed system, the amount of mass doesn't change over time.
In what state of matter has mass and it and it is the same each time?
Mass is a property that remains constant in all states of matter: solid, liquid, gas, and plasma. The total mass of a substance does not change when it undergoes a phase change because mass is a measure of the amount of matter in an object.
Why does mass not change when placed on the moon?
Answer 1: Your mass stays the same all the time because mass is the amount of atoms your made up of. Mass stays the same no matter where you are. The only reason your weight changes is because the gravitational pull on the moon is not a much as it is on Earth. Mass is how much is in you body not on the amount on you weigh
What equation do you use to find the rate of change?
Rate of change = amount of change in some period of time/amount of time for the change
Is time dependent on mass energy and distance?
Time is not dependent upon anything. Time is what it is. However, the amount of time necessary for something to happen IS dependent upon the amount of energy put into it, the amount of mass it is happening to and the distance across which it is happening.
What is the equation for the conservation on mass?
The equation for conservation of mass is mass in = mass out. This means that the total mass of a system remains constant over time, with the amount of mass entering a system equaling the amount of mass leaving the system.
Does the total amount of matter decrease overtime?
No, the total amount of matter in the universe remains constant over time, according to the principle of conservation of mass. Matter can change form or transform into energy, but it is not created or destroyed.
When soda is opened and left out for days does the mass change?
Yes, the mass of soda can change when left open for days because the liquid will evaporate, resulting in a loss of mass. Additionally, carbon dioxide gas can escape, further affecting the overall mass of the soda.
What is. Undulation?
a weather change in an amount of time.
The death of many species in a short time known as what?
The death of many species in a short amount of time is known as a mass extinction event. These events can be caused by a variety of factors such as natural disasters, climate change, or human activities. Mass extinctions have occurred several times throughout Earth's history.
What process causes the mass of a drying sponge to change?
