How did the matter in our universe arise from nothing?

The Universe as we observe it today began with the hot Big Bang: an early hot, dense, uniform. Perhaps, according to cosmic inflation — our leading theory of the Universe’s pre-Big Bang origins — it really did come from nothing.

How did all matter exist?

Origins. In the first moments after the Big Bang, the universe was extremely hot and dense. 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.

How does something come out of nothing?

The Universe is out there, waiting for you to discover it. Clearly, we exist, as do the stars and galaxies we see, so something must have created more matter than antimatter, making the Universe we know possible. …

Who said that nothing but matter exists?

[1] The concept itself is from British philosopher Gilbert Ryle,[2] from his The Concept of Mind (1949) made more popular by Arthur Koestler’s The Ghost in the Machine (1967). [3] It is, essentially, an argument against Descartes mind/body dualism.

Is everything in the universe made up of matter?

There can be no doubt: everything in the Universe is matter-dominated. In our own galaxy’s interstellar medium, the mean lifetime would be on the order of about 300 years, which is tiny compared to the age of our galaxy!

How did the universe come into existence from nothing?

The answer is that the universe cannot come into existence from literally nothing. Nothing in philosophical terms is not anything, it has no existence or properties. From nothing, nothing comes—ex nihilo nihil fit. The modern physicists will say that the universe came into being through a ‘nothing’ which is a quantum vacuum.

How do we know that matter/antimatter can be destroyed?

Here’s how we know. reaction (right), with matter/antimatter annihilating back to pure energy. This creation-and-annihilation process, which obeys E = mc^2, is the only known way to create and destroy matter or antimatter.

Is it possible to destroy a particle of matter?

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.
