Why Is Heart Rate Variability Important to Willpower?

What is heart rate variability? Why is heart rate variability important to willpower? Heart rate variability is the variance in time between each heartbeat. The higher the variability, the more relaxed and adaptable your body is to stress. This is related to willpower because people with higher heart rate variability are better at delaying gratification, dealing with stress, ignoring distractions, and exercising self-control. Continue reading for more information on heart rate variability and what you can do to increase it.

Autotelic Personality: Traits and Characteristics

How do you know if you have an autotelic personality? What does personality have to do with entering a flow state? If you’re naturally inclined toward finding flow in everyday experiences, you have an autotelic personality. If you’re an autotetic, you likely habitually do these four things 1) observe the environment around you, 2) set goals, 3) concentrate deeply on what you’re doing, and 4) enjoy a wide variety of experiences. Keep reading to learn what personality has to do with flow.

Stephen Hawking and A Brief History of Time

Is Stephen Hawking’s A Brief History of Time worth reading? What are some of the key topics explained in the book? A Brief History of Time is an exploration of the forces that govern our universe. It distills a wide range of topics, from Newton’s laws of gravity to special and general relativity, the Big Bang, black holes, the possibilities of time travel, the quantum theory, and more. Here is a brief overview of Stephen Hawking’s book A Brief History of Time: From the Big Bang to Black Holes.

Cosmic Inflation Theory and the Uniformity Problem

What is cosmic inflation theory? How does the inflationary hypothesis contradict the Hot Big Bang model? Cosmic inflation theory states that the early post-Big-Bang universe expanded at a rate faster than light in just a fraction of a second, resulting in a rapid supercooling of the universe (much faster than in the Hot Big Bang Model). This, in turn, resulted in a strong anti-gravitational effect which ironed out the wrinkles in its initial non-uniform state. Keep reading to learn about cosmic inflation theory.

The Beginning of the Universe: How It All Started

How did the universe begin? And how do we know that the universe had a beginning in the first place? The beginning of the universe has been debated by philosophers and theologians since the beginning of recorded history. But there’s no more need to continue the debates on the subject. We now know that the universe had a beginning. Without further ado, here is a simple explanation of how our universe began.

What Was There Before the Big Bang? A Singularity

What was there before the Big Bang? Did the universe just spring up into existence from nothing? While we can’t possibly be 100% sure, we do have an informed guess about the pre-Big-Bang state of affairs of the universe. We know that the universe today obeys concrete scientific laws, so it stands to reason that it had done so before the Big Bang. Here is out best guess at what happened before the Big Bang.

The Quest for a Unified Theory of Everything

What is the unified theory of everything? Is it possible to come up with both a correct and coherent explanation of all universal phenomena? A unified theory of everything is the ultimate theoretical framework that fully and coherently explains all universal phenomena. This is extraordinarily difficult and likely impossible, but humanity’s quest to achieve the ultimate understanding of the universe means we’ll keep trying. Keep reading to learn about the unified theory of everything.

The Hot Big Bang Theory: Everything It Overlooks

What is the Hot Big Bang Theory? What does the Hot Big Bang model tell us about the initial state of the universe? According to the Hot Big Bang Theory, the post-Big-Bang universe was extremely hot (hence the name). Because of that, particles were moving too quickly to coalesce together and form the building blocks of matter. The Hot Big Bang Theory explains a lot about the observable universe, but not everything. Here are some things it doesn’t account for.

The Heliocentric Model of the Universe Explained

What is the heliocentric model of the universe? Who proposed the heliocentric theory? In the heliocentric model, the sun is the static center of the universe and all of the planets revolve around it. It was proposed by Polish astronomer Nicolaus Copernicus in the 16th century, substituting the previously accepted geocentric model (where the Earth was considered the center). Here is how the heliocentric model of the universe came to be.
