Worried about black holes? Consider this: Every time you accelerate - you generate an event horizon behind you. The more you accelerate away from it the closer it gets. Don’t worry, it can never catch up to you, but the Unruh radiation it generates sure can.

Ever not felt completely like yourself? There's a good reason for that. Because a large part of you isn't actually you. Our bodies are home to ten times as many microbes as human cells. We are walking ecosystems, each of us home to thousands of different species on and inside of us. Meet your microbiome!

When it comes to dangerous asteroids striking Earth, it's not a matter of if, it's a matter of when. We have begun to track projectiles large enough to destroy our planet, and we are in the clear for the foreseeable future. However, there are countless asteroids large enough to take out an entire city that we cannot see. If you’ve ever watched the movie Armageddon, you know what we are talking about. There is a high probability that sometime in the future we would have to resort to those kinds of actions to save our planet. There is a reason to believe that it hasn’t been the first time an asteroid of large proportions changed the course of history when it fell on the Earth and wreaked havoc on it. The <a href="https://rumble.com/v4g2mr-s1-ep37-are-dinosaurs-extinct.html" target="_blank">dinosaurs</a> as species were wiped of the face of the Earth by an asteroid that hit the coast of the Yucatan peninsula, triggering a series of changes in the Earth’s climate and biodiversity. The first thing to do when under the threat of an asteroid hitting our only home is trying to locate it sooner rather than later. Efforts have been made to scan as much of the dark sky for flying rocks that are bigger than 500m, so that we are aware of their approach, but it’s still unclear as to where those smaller than 500m are. They are just like a grain of sand in the vastness of space. Other ways of <a href="https://rumble.com/v4cyjh-asteroid-impact-what-nasa-plans-to-do-if-a-killer-asteroid-will-hit-earth.html" target="_blank">dealing with them</a> include finding a way to change their trajectory, whether by kinetic or gravitational force.

Learn about Horizon radiation and why it's essential for us to understand as we continue our journey towards the Unruh Effect and Hawking Radiation.

Are matter, mass, and time real?

Inspired by Gene Roddenberry’s Star Trek, physicist Miguel Alcubierre set out to transform one of the cornerstones of science fiction iconography, the Warp Drive, into reality. But is it even possible? Can we "warp" the fabric of reality so that we can break the speed of light? And why is NASA actually exploring this potentiality?

A 24-year-old guy known as Z decided he had enough sleeping in this lifetime so one day in 1930, he approached a couple of researchers and ask them if they could help him stop sleeping. He was convinced that sleep is a habit and that with proper procedures the habit could be broken. On several occasions, he would have gone without sleep for four or five days. There are many experiments like this in the past and in this one, the guy Z thought if he could be stimulated by tasks and other people to stay awake more than a week he would never need to sleep again. He would break the habit. So, the researchers gave him a typewriter and ask him to type for thirty minutes a day marking each minute of typing. They would compare his typing speed and accuracy as one measure to find out the effects of sleeplessness. Throughout the ten days of not sleeping, his pulse, his blood pressure and the chemicals in his pee all stayed the same. He did a bunch of intelligence tests every day and his marks belly changed. But his typing speed declined and after day four he couldn’t type any more. He couldn’t fixate on letters and numbers and he said his eyes were sore. Still, Z stayed up and didn’t complained of <a href="https://rumble.com/viral/v1217871-chronic-fatigue-syndrome-information.html" target="_blank">mental or physical fatigue</a>. He didn’t become easily irritated. He started reporting hallucinations. On the last day of the experiment he wrote a nice poem and when the experiment ended, he slept. The researchers concluded that it was possible to go with practically no sleep for ten days without any known physiological effects or damage to mental functions. Similar studies found no damage from sleeplessness. Now after 50 more years research we know that sleep deprivation leads to depression, high blood pressure, diabetes, <a href="https://rumble.com/v3he57-natural-weight-loss-and-anti-aging-secrets-to-regain-your-health.html" target="_blank">weight gain</a> and heart diseases. A good night sleep is kind of a big deal. We need 7-9 hours at night for our memory to function. If we don’t sleep, we will never learn. Your body needs sleep, just as it needs air and food to function at its best. So, don’t forget to sleep.

Sometimes you just don’t want to make a whole new dinner. You don’t have the strength to open the cookbook, much less fighting with your spouse listening to their iPod during the meals. When you see a bunch of leftovers in the fridge, it’s like you’re Tom Hanks seeing the boat in ‘ Cast Away’. You’re saved. But, not so fast my friends, when it comes to reheating those leftovers, you may not know that you are probably doing it wrong. The average US adult eats 4.8 meals per week in restaurants. That’s almost 250 meals per year or 250 superfluous Yelp reviews. Well, with the restaurant's portions larger than they’ve ever been, most people are heading home with leftovers in tow. And in 90% of all homes, microwaves have been the primary choice for reheating most leftovers. What people don’t know though, is that microwaves may not be your best reheating choice. And when it’s all you have, you are probably doing it wrong. The idea of cooking food in the microwave was accidentally discovered by Percy Lebaron Spencer of the Raytheon company when radar waves accidentally melted a candy bar in his pocket. In the video, you can find multiple choices of how to reheat the <a href="https://rumble.com/v39pcn-pizza-stuffed-burger-roll.html" target="_blank">pizza</a>, which is the most common meal to be reheated. There are also great tips of reheating French fries and rice.

Could it be that all the electrons in the universe are simply one, single electron moving back and forth through time?

General Relativity! Spacetime! And... curved lines? On this week's episode of Spacetime, Gabe talks about what it actually means for a line to be straight so we can better understand what we mean by the idea of "Curved Spacetime". To make it easer he will divide this ground work at three parts: Part one: Geometry, part two: Spacetime, part three: <a href="https://rumble.com/v4g5eh-can-you-trust-your-eyes-in-spacetime.html" target="_blank">Spacetime</a> + curvature. This is part one of our series on General relativity, so be sure to check it out! Part one is about straight lines and curved spaced, no physics. Gabe gives great explanation about how a curve can be “straight” if tangent vectors stay tangent when parallel- transported along with that curve. Simple, isn’t it? This is great example with an ant confined to the surface of an ordinary sphere with no concept of or an access to the direction off the surface. From the ant’s two dimensional confined prospective, curve one between A and B is straight. The vector tangent to curve one at point A remains tangent all along curve one as we parallel transport it to point B. Once the ant does that over lots of curves joining A and B it finds that the tangent vector will remain tangent only. That segment is called a geodesic and piecewise it’s straight. Topology is global, but <a href="https://rumble.com/v36eq3-geometry-now.html" target="_blank">geometry</a> and curvature are local. Now what we have learned from Gabe is that in a three dimensional space you can test curvature just by moving a vector parallel to itself around a circle. If you end up with the same vector you started with space is flat, if not, it’s curved.

Although much of the Big Bang Theory is widely accepted to be true, it only gets us part of the way there. Observable truths such as the CMB and the flatness of our universe reveal that there is no way the universe has been expanding at a constant rate since its beginning. It turns out Cosmic Inflation solves the Big Bang's major problems quite well.

…or why we live on an onion made of magma

Some see string theory as the one great hope for a theory of everything – that it will unite quantum mechanics and gravity and so unify all of physics into one glorious theory.

Isaac Newton’s Universal Law of Gravitation tells us that there is a singularity to be found within a black hole, but scientists and mathematicians have found a number of issues with Newton’s equations. They don’t always accurately represent reality. Einstein’s General Theory of Relativity is a more complete theory of gravity.

Sometimes intuitive, large-scale phenomena can give us incredible insights into the extremely unintuitive world of quantum mechanics.

What will become of humanity after spend a few hundred years on Mars? What will happen after a few thousand? Evolution has, and still is, shaping humanity in rather drastic ways. How long will humans stop being human and become Martian?

Lurking in the depths of the mathematics of Einstein’s general relativity is an object even stranger than the mysterious black hole. In fact it’s the black hole’s mirror twin, the white hole. Some even think that these could be the origin of our universe.

Because you demanded it … we break down the EM Drive!

Have you ever asked “what is beyond the edge of the universe?” And have you ever been told that an infinite universe that has no edge? You were told wrong. In a sense. We can define a boundary to an infinite universe, at least mathematically. And it turns out that boundary may be as real or even more real than the universe it contains.

Biology textbooks are full of drawings of DNA, but none of those show what DNA actually looks like. Sure, they’re good models for understanding how DNA works, but inside of real cells, it’s a whole lot more interesting. Learn why we can’t look directly at DNA, and find out how DNA is actually packed inside cells.

Up until this point we've specifically been looking at government - that is answering the questions of who, what, and how in relation to policies. But politics is different in that it looks at why certain policies are made.

Did all of dark energy just vanish? A team of scientists have just analyzed new data and claim that we need to completely rethink its existence.

Let’s take a moment to remember the selfless sacrifices made by some amazing robotic explorers.

Why do humans cook? Holidays are celebrated in many ways, but chances are they involve eating, and eating a LOT. Ever wonder why we cook our food? We do it because it tastes good, of course, and because our customs and traditions are built around it. But we also cook our food for some basic biological reasons, because of evolution.
