♻️ What is the universe really made of?
The universe was very hot when it began to expand. We have fossil remnants of the very early universe in the form of neutrons, protons, electrons, and neutrinos, and the atomic nuclei that formed when the universe was 3–4 minutes old: deuterium, helium, and a small amount of lithium.

Hydrogen is the most common element found in the universe, followed by helium; together, they make up nearly all ordinary matter. But this accounts for only a tiny slice of the universe — about 5%.
WMAP determined that the universe is flat, from which it follows that the mean energy density in the universe is equal to the critical density (within a 0.5% margin of error). This is equivalent to a mass density of 9.9 x 10 -30 g/cm 3, which is equivalent to only 5.9 protons per cubic meter. Of this total density, we now (as of January 2013 ...
The universe (Latin: universus) is all of space and time and their contents, including planets, stars, galaxies, and all other forms of matter and energy. The Big Bang theory is the prevailing cosmological description of the development of the universe.

What is the Universe made of? The Universe is thought to consist of three types of substance: normal matter, ‘dark matter’ and ‘dark energy’. Normal matter consists of the atoms that make up stars, planets, human beings and every other visible object in the Universe. As humbling as it sounds, normal matter almost certainly accounts for ...
The galaxy is only about 100,000 light years across, so even at 1% of the speed of light, it takes 10 million years to cross the galaxy. We evolved from small mammals to tool-using humans with space rockets over less than 100 million years. The invention of writing to the Apollo Program is maybe 10,000 years or less.

However, if you just want a short answer, I'll say this: if the universe is infinitely big, then the answer is simply that it isn't expanding into anything; instead, what is happening is that every region of the universe, every distance between every pair of galaxies, is being "stretched", but the overall size of the universe was infinitely big to begin with and continues to remain infinitely big as time goes on, so the universe's size doesn't change, and therefore it doesn't expand into ...Is the universe really infinite?
A Final Word. There remains no clear or definitive evidence that the universe is either finite or infinite, although there are some intriguing arguments and proposed theories on both sides. The great thing about this mystery, however, is that due to the nature of the universe, we may never be able to truly know the answer!Is the universe really logical?
We try to break what we observe about the universe into logical parts and draw inferences and come up with axioms to explain other properties. We also try to combine different forces so as to come up with a unified theory. In other words, we can say that humans have a predilection towards finding logical patterns.Is the universe really mathematical?

Matter and energy, which according to E=mc2, are interchangeable.Another answer:To be technically correct, we are talking about mass, not matter. Einstein's equation e = mc2 does not necessarily mean that mass and energy are interchangeable - it means that they are the same thing. Mass is energy, and energy is mass. Its not an issue of converting from one to the other - its a matter of them being the same thing - just different frames of reference.
