Can matter be created from nothing?
The first law of thermodynamics doesn’t actually specify that matter can neither be created nor destroyed, but instead that the total amount of energy in a closed system cannot be created nor destroyed (though it can be changed from one form to another)..
How old is our universe?
13.8 billion yearsSuch a figure was rather mind-blowing and also pretty baffling. As astronomer Howard Bond of Pennsylvania State University pointed out, the age of the universe — determined from observations of the cosmic microwave background — is 13.8 billion years old.
How can the universe end?
The ultimate fate of an open universe is either universal heat death, a “Big Freeze” (not to be confused with heat death, despite seemingly similar name interpretation — see §Theories about the end of the universe below), or a “Big Rip”, where the acceleration caused by dark energy eventually becomes so strong that …
Is nothingness possible?
There is no such thing as nothingness, and zero does not exist.
What does E mc2 mean?
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.
What is outside the universe?
In our own backyard, the Universe is full of stars. But go more than about 100,000 light years away, and you’ve left the Milky Way behind. Beyond that, there’s a sea of galaxies: perhaps two trillion in total contained in our observable Universe.
How the matter was created?
As the universe cooled, conditions became just right to give rise to the building blocks of matter – the quarks and electrons of which we are all made. A few millionths of a second later, quarks aggregated to produce protons and neutrons. Within minutes, these protons and neutrons combined into nuclei.
Where did matter come from?
According to the big bang theory, equal amounts of matter and antimatter were created at the birth of the universe, but precious little antimatter is to be found in the universe today. Everything we see, from our bodies to our cars to the stars in distant galaxies, is made of matter.
Can matter be created?
Water is composed of two hydrogen atoms bonded to an oxygen atom. Photograph by OJO Images Ltd. From port-a-potties to supernovas, matter makes up everything visible in the known universe. Because matter is never created or destroyed, it cycles through our world.
Why does anything exist at all?
Why is there something rather than nothing? The sufficient reason […] is found in a substance which […] is a necessary being bearing the reason for its existence within itself. Philosopher of physics Dean Rickles has argued that numbers and mathematics (or their underlying laws) may necessarily exist.
What Cannot be created or destroyed?
The First Law of Thermodynamics (Conservation) states that energy is always conserved, it cannot be created or destroyed. In essence, energy can be converted from one form into another.
Has matter ever been created?
Every interaction between particles that we’ve ever observed, at all energies, has never created or destroyed a single particle of matter without also creating or destroying an equal number of antimatter particles.
Who created God?
Defenders of religion have countered that the question is improper: We ask, “If all things have a creator, then who created God?” Actually, only created things have a creator, so it’s improper to lump God with his creation. God has revealed himself to us in the Bible as having always existed.
Does empty space exist?
Quantum mechanics tells us that there is no such thing as empty space. Even the most perfect vacuum is actually filled by a roiling cloud of particles and antiparticles, which flare into existence and almost instantaneously fade back into nothingness.
Who created universe?
In his 1988 book, A Brief History of Time, Hawking had seemed to accept the role of God in the creation of the universe. But in the new text, co-written with American physicist Leonard Mlodinow, he said new theories showed a creator is “not necessary”.
