Hubble Spotted New Evidence That Dark Matter Is “Cold”

Cosmologists know that dark matter must exist. If it didn’t, the rate galaxies spin would tear them apart— so there must be something unaccounted for generating the gravity that’s holding them together. Something that doesn’t interact with regular matter in any other way that we’ve detected yet. What exactly that something is, is anyone’s guess—and […]

This Is the Biggest Neutron Star Collision We’ve Ever Detected

Gravitational waves resulting from crashing neutron stars have rocked our universe once again. And while you may not have felt it, LIGO sure did. And these gravitational waves are the ripples from a collision of the most massive neutron star pair we have ever witnessed. As you may know, this isn’t LIGO’s first rodeo with […]

China’s Crazy Plan to Launch an Artificial Moon

Guess what? China has announced plans to launch an “artificial moon” into our skies by 2020. And, as crazy as that sounds, it’s not actually the first time something like this has been attempted.

What Does It Take to Enrich Uranium?

Nuclear programs are constantly in the news, with reports that they’re enriching uranium. Usually, the stories mention percentages and centrifuges, but to the uninitiated, it’s not clear why these things are important. What exactly does it mean to enrich uranium? And at what point should we be worried? Now when I imagine enriching uranium, I picture […]

Earth’s Magnetic North Pole Is Shifting South… So What Now?

You may have heard that the earth’s magnetic poles tend to move around. I mean, so do the geographic poles, but magnetic North and South are really mobile…and magnetic North in particular is moving real fast. Like, way faster than we thought it would. And the scientific community is coming up with some really exciting […]

We Could Soon Turn Any Blood Type Into Universal Donor Blood

Back in the 19th century, if you needed a blood transfusion, it was a risky proposition. When doctors tried to remove one person’s blood and put it in someone else, sometimes it was a success. But sometimes the blood would clump together, which could result in death. And this is the kind of procedure you […]

Solar Orbiter Will Take Mankind’s First Images of the Sun’s Poles | Countdown to Launch

For the last year, Parker Solar Probe has broken records in speed, collected unprecedented data, and achieved the closest approaches to the sun ever. But none of these insights were detailed images of the sun directly, I mean, if we’re heading to the only star in our planetary system, we want to see it, up […]

Chemical EFFECTS of Electric CURRENTS Part 1 – Physics Class 8th CBSE #11

In your previous grade you must have learnt about electrical conductivity in solids. There are good conductors of electricity, weak conductors of electricity and bad or non-conductors of electricity. Here we’ll see how they behave. In this set up, all the connections are there, only one part is missing and that will tell us about […]
