If matter cannot be created or destroyed where does it come from?

Answer 1

That's a simplistic description of one of the conservation laws of physics. Matter and energy are conserved, but you can convert one to the other.

If you're asking where it all came from in the first place, that's a first class unanswered question. The standard model of cosmology can't extrapolate farther than a big bang singularity. Even if some version of M-brane theory turns out to be correct and useful, and the big bang is the result of the intersection of many-dimensional membranes, that just pushes the question back to where did these branes come from.

Answer 2

Assume a multi-dimensional space within which there are quantum fluctuations. Very very rarely, some of the largest fluctuations are close enough to combine and cause a localised instability in this space. One of these instabilities caused our 4-dimensional universe (3-d space plus time) via the "Big Bang", the energy coming either from the collapse of extra dimensions or the opening out of our 4 spacetime dimensions. This energy was eventually converted into matter and antimatter in equal amounts but, during the early universe, the nature of the vacuum was different than it is now (different latent energy) which ensured that one of the forms (antimatter) decayed considerably faster than the other (matter). In the Standard Model of particle physics, antimatter decays faster than matter at a rate about 10,000 times too small to account for the imbalance of matter over antimatter in our universe (from Kaon and B-particle decays), but this is measured in the vacuum which we inhabit now, not the energy-dense vacuum shortly after the Big Bang.

Answer 3

The big bang says it all came from a tiny speck of pure energy called a singularity, 10-43 seconds after this singularity appeared the energy began to expand and the first particles came into being, from there all that exists today evolved and none of it can be destroyed and no more can be created.

Answer 4

All matter has been with us since time began in every conceivable form. Newly created elements and compounds are derived from available matter somewhere.
Matter still cannot be created nor destroyed, even in atomic reactions, it's still being converted to other forms.

Answer 5

Possibility 1:
The matter that existed at the first "instant" in time came directly from the last "instant" in time. This is because we live in a temporal loop which means that the far future meets the distant past.

Possibility 2:
Matter and antimatter cancel each other, which means absolute nothingness can become equal amounts of matter and antimatter which appear and disappear rather as water droplets condense and evaporate in clouds. For reasons external to our own universe a rip occurred in the 5th dimension in such a way as to suck a large proportion of the antimatter into a parallel universe. This left far more matter than antimatter in our own universe resulting in the persistence of matter as it could no longer be cancelled.

Possibility 3:
Matter cannot be created or destroyed because matter doesn't exist. It's all an illusion. The physical universe is an illusion. You are an illusion. All that exists is my awareness in a private universe of my own called Solipsism.

Possibility 4:
We are all one consciousness but we don't know it. The reality of this is far deeper in our psyches than we can see. With the massive mental power of this universal mind we have created the universe and all its features including matter.

Possibility 5:
Matter originated in the super-computer which maintains this virtual reality in which we (unknowingly) live.

Answer 6

the big bang theory states that before there was space and time, there was a super hot, super dense TINY volume of matter. In this space ALL the matter in the universe today was located. Eventually it exploded, starting space and time. The universe continues to expand today at the speed of light

Answer 7

All the matter in the universe already exists, from the beginning of the universe there has always been the same amount, so it dosnt come from anywhere.

Answer 8

ufff!!! Theoretically speaking when the world and the universe appears and exist, they are made of matters that's it!

Biblically speaking! When God created the whole world with those elements air, water, light, soil, flesh etc. within six days wow they are perfect!!!

I can say that God created matter.

I can say the origin of it is supernatural.

Answer 9

The total amount is fixed. This statement only applies to new stuffs. Science is confusing for me too.

Answer 10

What can the matter be.

There. I've crafted an answers as stupid and pointless as everyone else's on this thread. I can go to bed proud.
