Why Mark Kelly Is Now Older Than His Older Twin Brother

Astronaut Scott Kelly returned from a year-long sojourn in space in June. His slightly older twin, Mark Kelly, stayed home as a control—part of NASA’s twin study to monitor the effects of space on the human body. But there’s a physical change that NASA might not be able to measure that easily. Mark is now even older (by about 5 milliseconds) than his space-faring twin, thanks to special relativity.

The Surprisingly Complex Way That Scientists Measure Sea Level

Most of us have probably never given a second thought as to how sea level is determined. It's basically where the ocean starts, right? Not even close. It turns out there are countless factors that have to be taken into account because the oceans simply aren't at the same level all around the world. Read More >>

Comparing the Universe to the Pixels In This Video Puts Its Massive Scale Into Perspective

Taking advantage of its medium of choice, Minute Physics makes the incredibly-vast scale of the observable universe a little easier to comprehend by comparing it to the 2,073,600 pixels in this 1080P video. But be forewarned: drawing similarities between the earth and a single pixel in this clip isn't going to help if you're already suffering from feelings of insignificance. Read More >>

What Is the Universe In One Minute

What is the Universe? Is the Universe everything there was, is and will be? Is the Universe everything we can observe and things we know exist but haven't been observed yet? Is mathematics part of the Universe or do they exist outside of the Universe? This one-minute-long video shows exactly what the Universe is—but proceed with caution, as it may give you a bit of a headache. Read More >>

In Case There Was Still Any Doubt, Here’s the Top Ten Reasons We Know the Earth Is Round

At this point it's hard to find a skeptic who would raise an eyebrow at the notion that our planet is round. But every family has that one uncle or cousin who's so caught up in conspiracy theories they'll question anything. And if you happen to find yourself in a tedious argument defending the spherical nature of the Earth, Minute Physics has put together a useful top ten list of irrefutable facts proving our home is indeed round.

Will We Ever Be Able to Predict Everything?

As super computers get more and more super, you'd think that eventually we'd be able to calculate the position and interactions of every atom in the universe and be able to accurately predict the future. In fact, this was once a widely held belief in science, until quantum mechanics arrived and put an end to that theory. Read More >>

How Quantum Mechanics Was Born From the Need For a Better Lightbulb

Some of mankind's most remarkable scientific discoveries came to light as a result of research that had nothing to do with the breakthrough itself. And such was the case with quantum mechanics. Back in the early 1890s the German Bureau of Standards asked Max Blanck to design a lightbulb that produced the maximum amount of light with the minimal amount of energy. And his research into saving the bureau a few Deutsche Marks on its energy bills led to the study of quantum mechanics which could one day let us unlock the secrets of the universe. Read More >>

Is Usain Bolt Actually Faster Than Gravity?

Usain Bolt is fast. Like, really fast. He's pretty much the fastest dude that ever was fast. And while that's impressive in its own right, could it be that he's actually faster than gravity, one of the fundamental forces that rules the very nature of the universe in which we live? Well, that's sort of a weird question to try and answer, but that hasn't stopped MinutePhysics from poking at it. The answer is SPOILER ALERT "maybe, sort of" but I'll let the master explain the details. Suffice it to say you don't ever want to be running from Usain Bolt. [YouTube] Read More >>

How One Infinity Can Be Bigger Than Another

Infinity is a pretty difficult concept for us to grasp. The world we live in is full of limitations, so the idea that something can go on and on, forever and ever, doesn't come naturally to us. And to make things even more confusing, some infinities can actually be bigger than others. Read More >>
