Pulsed Plasma Thrusters

While travelling in space, one of the hardest things to do is to stop or change direction. Without anything to push against or friction to slow things down, spacecraft need to do all the hard work of changing their speed or path by there thrusters. And sometimes they do that in ways you would never … Read more

Let’s Understand Black Hole

Black holes are among the most fascinating objects in our universe and also the most mysterious. A black hole is a region in space where the force of gravity is so strong not even light the fastest known entity in our universe can escape.  The boundary of A black hole is called the event horizon a point of no return beyond which … Read more

Let’s Understand White Holes

White holes are almost definitely not a real thing that can be found in nature. In theory, white holes are black holes that are going backwards. In theory. A black hole, as you know, is a giant object that sucks stuff into a singularity – a single point of infinite density – from which there is no escape. So a white … Read more

How Submarines Work?

In all of World War Two, the world used about 5 megatons of explosives. But now, a single American Ohio Class submarine can carry 24 Trident II missiles. Only one Trident II missile capable of carrying 12 nuclear warheads together equivalent in power to about 5 megatons of explosives. A single submarine can carry a … Read more

But beyond this realm of knowledge, another world shined brightly just waiting to be discovered. Uranus is the seventh planet from the Sun, from a distance of about 20 astronomical units or 20 times the distance between Earth and the Sun. Uranus orbits the … Read more

Venus Spins Backwards, But Why?

After studying the solar system for hundreds of years, you would think we, at least, have the basics figured out, stuff like why planets spin and orbit the way they do. Except, we totally don’t. And you only have to look at the planet next door to see it. When scientists began observing Venus in detail in the 1950s … Read more
