What keeps the space empty?
Space is not empty.
A point in outer space is filled with gas, dust, a wind of charged particles from the stars, light from stars, cosmic rays, radiation left over from the Big Bang, gravity, electric and magnetic fields, and neutrinos from nuclear reactions..
Who created the universe?
A creator deity or creator god (often called the Creator) is a deity or god responsible for the creation of the Earth, world, and universe in human religion and mythology. In monotheism, the single God is often also the creator.
Is energy ever completely lost and gone forever?
The law of conservation of energy, also known as the first law of thermodynamics, states that the energy of a closed system must remain constant—it can neither increase nor decrease without interference from outside.
Are humans just energy?
In life, the human body comprises matter and energy. That energy is both electrical (impulses and signals) and chemical (reactions). … Remarkably, at any given moment, roughly 20 watts of energy course through your body — enough to power a light bulb — and this energy is acquired in a plethora of ways.
Can light be destroyed yes or no?
Photons are easily created and destroyed. Unlike matter, all sorts of things can make or destroy photons. … The movement of electrons is responsible for both the creation and destruction of the photons, and that’s the case for a lot of light production and absorption.
Why does light travel so fast?
According to Einstein’s general theory of relativity, as an object moves faster, its mass increases, while its length contracts. At the speed of light, such an object has an infinite mass, while its length is 0 — an impossibility. Thus, no object can reach the speed of light, the theory goes.
Can energy be lost?
In systems, energy can be lost when it is transformed from one form to another (for example, chemical energy to thermal energy). Energy can also be lost when it is transferred from one part of the system to another (for example, driver gear to follower gear).
How do you find energy lost to heat?
To calculate the amount of heat released in a chemical reaction, use the equation Q = mc ΔT, where Q is the heat energy transferred (in joules), m is the mass of the liquid being heated (in kilograms), c is the specific heat capacity of the liquid (joule per kilogram degrees Celsius), and ΔT is the change in …
Where do our atoms go when we die?
When we die, our atoms will disassemble and move off to finds new uses elsewhere – as part of a leaf or other human being or a drop of dew. Atoms themselves, however go on practically forever.
Are humans made of matter Yes or no?
The particles we’re made of About 99 percent of your body is made up of atoms of hydrogen, carbon, nitrogen and oxygen. … If we lost all the dead space inside our atoms, we would each be able to fit into a particle of lead dust, and the entire human race would fit into the volume of a sugar cube.
Do humans have kinetic energy?
Kinetic energy is also generated by the human body when it is in motion. … Studies have also been done using kinetic energy and then converting it to other types of energy, which is then used to power everything from flashlights to radios and more.
What does E mc2 mean?
E = mc2Einstein’s Big Idea homepage. E = mc2. It’s the world’s most famous equation, but what does it really mean? “Energy equals mass times the speed of light squared.” On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
Did Energy always exist?
(1) It has always existed. The universe is infinitely old, and energy (the same amount of energy) has always existed. … The gravitational field has negative energy, and the total amount of energy in the universe, positive energy due to massless particles and matter, plus the negative energy due to gravity, is zero.
What happens to energy lost in living organisms?
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels.
How is kinetic energy lost in a collision?
In a perfectly inelastic collision, i.e., a zero coefficient of restitution, the colliding particles stick together. In such a collision, kinetic energy is lost by bonding the two bodies together. This bonding energy usually results in a maximum kinetic energy loss of the system.
Where does energy go when it seems to have disappeared?
There is law called Law of conservation of energy which theoretically states “the total energy of an isolated system remains constant—it is said to be conserved over time. Energy can neither be created nor destroyed; rather, it transforms from one form to another.”
Can an atom be destroyed?
All matter consists of indivisible particles called atoms. Atoms of the same element are similar in shape and mass, but differ from the atoms of other elements. Atoms cannot be created or destroyed. … The atom is the smallest unit of matter that can take part in a chemical reaction.
Is energy lost when machines don’t work right?
Answer: Energy is lost when machines don’t work right. Explanation: As per law of conservation of energy we can say that energy will convert from one form to another form in an isolated system but the total energy of the system will always remain conserved.
Does nothing exist?
‘Nothing exists’ is simple in the sense of being an easy to remember generalization. … There is no such thing as nothingness, and zero does not exist.
Can light be destroyed?
YES, light can be destroyed , but its energy cannot be destroyed . when the energy in the light changes to another form(like heat)..you can say that light is destroyed. … If you meant destroying energy that photons possess, no you can’t destroy it. In the above example the energy is just converted into heating water.
