This video introduces atoms, molecules, and the big bang theory that proposes the creation of matter.

Where is the center of the universe? All this, everything you see around you, started in a big bang, from a point smaller than the point at the end of this sentence. It as an infinitesimally small point, called a singularity....

Stars represent a celestial battle of two opposing forces, gravity trying to collapse the star, and radiation pressure trying to explode the star. But it comes to an end close to the time that it runs out of fuel. Gravity...

Quantum Creation – what came before the big bang - the mechanism of a universe out of NO-thing - no matter, no space, and no time. Ancient Greek cosmologist Parmenides said “Nothing comes from nothing.” He was...

Is dark matter real? What is dark matter made of?Axions, Wimps, Machos explained. (Part 2 will be "why dark matter may not be matter at all") One of the biggest questions in science is: What is the...

If we look as far out as possible, we would see a uniform glow of low level radiation in all directions. This is called the cosmic microwave background, or CMB. It is the oldest light in the universe. And it...

What came before the Big Bang? what happened before the big bang? Since time is thought to have started at the big bang, asking what happened "before" is like asking what is North of the North pole? It may have no...

The universe, shortly after the big bang only consisted of the lightest elements, Hydrogen, Helium Lithium, and some isotopes. But today we have elements on earth as heavy as Californium, element 98 on the periodic...

if you took a notebook, a plastic bottle, a toaster, and a glass container and burned them in a fire hot enough, around 10^31 degrees Celsius, all the particles and forces, would become one entity. This is what...

Standard Model of particle physics, Explained simply. The structure of matter, that is, everything you see in the universe – you, me, the earth, stars happens to be made up of some core fundamental particles...

What if the universe is self-aware? Is there a cosmic superconsciousness? Could it be a giant brain? Is the universe a conscious mind? There is a short but lazy answer, and there is longer but more...

SUMMARY:

Why are we here? Why is there something instead of nothing. Part of the answer is rooted in physics. Matter is not the simplest thing there could have been. The simplest thing In physics is...

How will the universe end? Whether you think the universe is good, bad or indifferent, it will come to an end…someday. How will that happen? Will it simply die a slow death over time? Will it die dramatically in a big...

Then Isaac Newton in 1687 showed that planets move due to the same forces we experience here on earth. If things could be explained with mathematics, to many people this called into question the need for a...

What is this mysterious quantum tunneling effect, where does it come from? And why is it one of the most important phenomena in physics?

Quantum mechanics shows that quantum objects have a wave-particle...

Is a theory of everything really possible? What makes us think it even exists? If we look at historical precedent, we can see that we have united seemingly completely unrelated forces and particles to a...

Could the universe be in a metastable, or false vacuum state? Could there be a looming vacuum catastrophe waiting to happen? Is the universe doomed?



This is related to the Higgs boson and the heaviest...

James Webb captures infrared light, which allows us to see billions of light years away. Some galaxies would not be visible otherwise, because their light has redshifted beyond visible light spectrum due to the...

Does a final theory exist that can end our reductionist probing into ever shorter distances? Or is there no end to reductionism? There should be an end point because as the object of our measurement gets small...

The Milky way galaxy is composed of up to 400 billion stars, and at least that many planets. Our star, the sun is one of those billions, about a third to halfway out from the galactic center....

Summary:

The information that we know about the universe comes almost exclusively from the analysis of electromagnetic radiation. But there is only so much this light can reveal because there is an inherent...

Summary:

The big bang model has some problems - homogeneity, flatness, and lack of magnetic monopo

Cosmic Inflation occurred when the entire universe shortly after its beginning, expanded exponentially...

The closest thing we have to an all-encompassing framework that explains all particles and forces is represented by the Standard Model of particle physics. But this model is flawed because it does not...
