I believe there was a moment where the universe was created, and I think it was the big bang. But where did the matter come from?

I'm not sure that any of the science-based answers above get to the heart of the question, which I presume to include the energy from which matter arose, inasmuch as mass-energy equivalence is now a vital pillar of modern physics and cosmology. Perhaps the question could be rephrased as
"Where did the mass-energy come from?" And that's a lot harder to answer.

Physics seems to have a pretty good handle on the processes that occured during most of the event known as the "Big Bang". Unfortunately, the problem of the ultimate origin of mass-energy gets more difficult as we approach ever closer to the actually initial moment of the universe's appearance. Amazingly, cosmologists measure time in the earliest moments of the universe in vanishingly small fractions of a second.

By the end of the universe's first second, several dramatic transformations and processes have occurred, and "ordinary" matter, as you and I might think of it, has just begun to appear on the scene. Large-scale structure, such as stars, galaxies, and galactic clusters, won't appear till roughly 300 million years later.

But let's get back to that first second. This brief period actually sees several major universe-shaping "epochs" that determine the structure and features of everything that comes afterward. The period after the first 1 E-43 seconds (that's 0.0....1 with 42 zeros between the decimal and the one- an unimaginably small fractionn of a second!) seems to be fairly "easy" to describe using the tools of physics that exist today. It's what happened before that first 1 E-43 seconds that's giving cosmologists real fits. That period is called the Plank Epoch. Most notions about space-time, mass-energy, and other physics phenomenon are meaningless during this epoch. While several new theories, most of which fall under the banner of "quantum cosmolgy", have had some early success, they remain highly speculative. It is not yet known if these lines of research will lead to any meaningful description of the universe's earliest moment. At the present time, physics and cosmology are unable to probe into the period before 1 E-43 seconds. In short, that simply means that no one knows "where did the mass-energy come from".

Even if we ultimately understand the processes that occurred during the Plank Epoch, all the way back to Time Zero when the shrunken universe blinked into existence, the question will still remain- what caused the universe to come to be? Interestingly, even some physicists and cosmologists believe that there is a limit to how far back science can look, and that anything they say about what happened before Time Zero may remain purely a matter of speculation, philosophy, or faith.

The cosmos was built with the tools which man calls music, arithmetic, geometry; harmony, system, and balance. The building blocks were all of the same material, which man calls the life essence. It was a power sent out from God, a primary ray, as man thinks of it, which by changing the length of its wave and the rate of its vibration became a pattern of differing forms, substance, and movement. This created the law of diversity which supplied endless designs for the pattern.

Each design carried within it, inherently, the plan of its evolution, which was to be accomplished by movement, growth, or, as man calls it, change. This corresponds to the sound of a note struck on a piano. The sounds of several notes unite to make a chord; chords in turn become phrases; phrases become melodies; melodies intermingle and move back and forth, across and between and around each other, to make a symphony. The music ends as it began, leaving emptiness, but between the beginning and the finish there has been a glorious beauty and a great experience.

When you ask the question 'where did it come from?', you are implicitly assuming that there is a time *before* the big bang. This is very possible an incorrect assumption. Remember that time itself is part of the universe and is affected by large concentrations of matter and energy. Because of this, it is possible (and for general relativity, it *is* the case) that time simply cannot be extended past the instant of the big bang. It is somewhat like asking what is north of the north pole. The question itself is the problem.

Once you get away from strict general relativity, it is possible that time can be extended to before the big bang, but in that case, there was a collapsing universe before ours that provided the mass and energy.

All the matter in the Universe are from the energy released in the Big Bang. A tremendous amount of energy was release as a result of the Big Bang. We see the remnant of that event as the Microwave Background Radiation that permeates the entire cosmos. As the Universe cooled, it went through a kind of phase transition, where there was one force, now there are four distinct and separate kinds of forces, gravity, weak, strong and electromagnetic. In addition, energy contained in the vacum of spacetime itself spontaneously created particle-anti-particle pairs. Some of which survived as matter to today.

It comes from energy. Matter is believed to be energy which has condensed into tiny entities of circulating energy. These tiny entities are the "particles" which make up all matter as we know it.

e=mc^2 is the equation that tells us just how much energy is "trapped" inside each particle of matter. The only weak analogy I can offer is to think of matter as tiny bundles of energy which will expand outwards in all directions at the speed of light (as electromagnetic waves) if the "shell" of the bundles is breached.

well... it did not come FOR the Big Bang, it came FROM the Big Bang.
It was the Big Bang that produced it.

It was created from nothing. All that exists in the universe is a product of 'NOTHING'.
Our creator cannot be comprehended.

Hi.Matter and energy are different forms of the same "stuff".
