What is time travel? Is time travel possible?

Time travel is one of those topics for which I always get goosebumps when someone talks about it and I turn super excited and thrilled. And of course, it is one of my favorite topics. Today we gonna talk about time travel and it’s possibilities. So let’s get started. (more…)

Wormhole: A passage to a new world?

In the previous article, we had discussed the black holes and its futuristic possibilities of time travel. If you don’t read it yet then please go through it, the link is here. So in today’s article, we shall discuss the wormholes, a similar kind of concept as blackholes but they are different from black holes. So let’s get started.

What is a wormhole?

A wormhole is a theoretical passage through space-time that could create shortcuts for long journeys across the universe. The term wormholes first introduced in the theory of general relativity by Einstein. He also told that we can use it as a tunnel for the journey between two universes. (more…)

Black hole: The monster of space

In today’s article, we gonna talk about one of the most fascinating and mysterious objects in the space i.e. Black hole. So don’t waste any more time, let’s get started.

What are black holes?

Physicist Albert Einstein first mentioned the black holes in 1916 with his general theory of relativity. Black holes are one of the strangest and most fascinating objects found in the space. They have extreme density and mass, exist at a point called the singularity. With such strong gravitational attraction, any atomic particles even light cannot escape from it. The gravity is so strong because the matter has been squeezed into a tiny space. (more…)

General Theory of Relativity: The advanced key to explore the cosmos.

In the previous post, we discussed the special theory of relativity. If you didn’t read it yet, then please go through it by clicking here before going through this post, otherwise, you will not be able to understand it. In this post, we will discuss the modified theory of his previous theory i.e General Theory of Relativity. So let’s get started.

General Theory of Relativity

In 1905, physicist Albert Einstein determined that the laws of physics are the same for all non-accelerating observers and that the speed of light in a vacuum was independent of the motion of all observers. This was the theory of special relativity. It introduced a new framework for all of physics and proposed new concepts of space and time. (more…)

Einstein’s special theory of relativity. A key to explore the cosmos.

What is the special theory of relativity?

In 1905, A German-born theoretical physicist, Albert Einstein published the theory of special relativity (or special theory of relativity), which explains how to interpret the motion between different frames of reference i.e. inertial frame of reference and non-inertial frame of reference i.e. places that are moving at constant speeds relative to each other and places that are moving with variable speeds relative to each other respectively.
