Is ‘Time’ really here!

Now don’t get away reading that, you all are good readers, isn’t it!

From a perspective of a physicist time is everywhere, it does not have any boundaries and it does not need any laws, but time is also really chilly.

According to me time goes with space, and space carries matter, thus if anyone of those get away all of them will get destroyed.

Since physicists say that before the big bang their was no time thus their was no before.

Check out this video which describes how we understand the time but what really is time, with the correlation of the big bang theory.

Big Bang, Big Trouble!

In the early 20th century, physicists such as Albert Einstein, George Lemaitre, Edwin Hubble and many more were very busy in their work. Einstein provided General Relativity, George Lemaitre proposed The Big Bang and Edwin Hubble discovered that galaxies are moving apart from each other. But do all these are correlated.

Even today we think that Big Bang is the solution of all, but then we think before the big bang their was……what?

Einstein’s general relativity can’t work without space and gravity. And they said that before the big bang their was no time, thus their was no before.

So how anything come from nothing, especially when we are talking about the ‘Big Bang’ scenario.

These are the points to be remembered-

  • Einstein’s general relativity can’t work without space and gravity.
  • Big Bang theory doesn’t tell us anything about how universe came from nothing.
  • Why space is expanding, and why we cannot travel across the galactic superclusters – ‘Dark Matter’.

Now I think we got our answer, all these are correlated, the general relativity, big bang and the expansion of the space.

Until we don’t know that, we cannot solve that puzzle.

General Relativity Continues [2]

Hello my readers and friends, last time we talked about Albert Einstein’s general relativity, which was published in 1916, so today we will complete our talk on this topic. But to be simple, general relativity is also quite complicated for us, but please read it till the end.

Albert Einstein proved that space is not limited to any extent, thus it can change its shape according to its place.

Albert Einstein predicted Gravitational Waves in his theory, in which he stated that when two bodies with large amount of mass orbit each other, their orbits create ripples in the space time, which propagate at the speed of light. These waves travel across the space and are really very difficult to be detected. However these waves are created when two Neutron Stars or Two monster Black Holes orbit each other. So these waves are really very important to detect black holes and neutron stars in the universe. In 2016 The Advanced Ligo Team declared that they had successfully detected gravitational waves by the merging of two black holes.

This is a real proof that black holes really exist.

Albert Einstein’s equations are really very difficult to be understand but these equations describe the most fundamental functions of the universe.

Albert Einstein gave us the theory which has provided us some of the most crucial facts about the universe. General Relativity has completely changed the view of how we look at the universe.

This is the end of our story about Albert Einstein’s General Relativity, but still their are many unanswered questions about this theory, but there’s no doubt that this theory is the most beautiful theory we have in all of science.

General Relativity can be described as “The answer of everything”.

That’s all we have for this post, but we will come back with some more interesting facts related to space.

General Relativity Continues [1]

Hello my readers, and friends, when we last time left we had a talk about General relativity, by Albert Einstein which was published in 1916. Today we will continue our talk on this topic.

General relativity describes that gravity and acceleration both are same, thus light rays coming from other stars will be bend by the Gravitational force of our star, the sun. But, it is rather more complicated. Einstein proved that space is like an bed sheet on which stars and planets are been rolling. Thus he stated that the object with more mass will bend space more than the others. So the bending of the space depends upon the mass of that object.

So earth bends space around it, the sun bends space around it, and when we move to the objects with more mass like Red Supergiant stars and black holes, curvature of the space becomes more bigger.

Thus more the mass will be, the more will be the curvature.

Albert Einstein’s original equation of the general relativity has been used with many more equations.

Their are many more facts remaining on Albert Einstein’s general relativity, we will explore them in our next post.

General Relativity!

The most famous theory of the modern century, general relativity is one of the two pillars of the modern physics with Quantum Mechanics. It was proposed by Albert Einstein, published in 1916.

It has been a revolution in the world of physics, enabling scientists and physicists to solve some of the most mind crushing theories.

We will talk about general relativity in many parts. So here’s our first part.

General relativity tells us the most fundamental things about the gravity and its effects on other things. It also describes the functioning of the space time in the universe. Like that space isn’t a stage, it is himself an actor. His theory has been put onto the work many times and its potentially the most powerful tool in astronomy and in physics as well.

General relativity has been used with cosmological constant, quantum mechanics and many more. Cosmological constant was also been given by Albert Einstein.

General relativity and quantum mechanics has still not been reconciled, but scientists are trying to do it with the help of quantum gravity.

General relativity has many good solutions for black holes, dark matter and dark energy. It also helps in the solutions of Gravitational waves, which was also being predicted by Albert Einstein.

There are a lots of facts related to General relativity, we will talk about them in our coming posts.

Special Relativity Continues!

Hello everyone, last time we talked about special relativity, and today we will continue our talk.

Special relativity tells us that how space and time behave. It tells that when we move faster we see time run slowly, it’s due to because time shrinks.

Einstein proved that space tells matter how to move, and matter tells space how to bend.

Einstein said that laws of Isaac Newton doesn’t fit into spacial things, and that’s what made him develop mass-energy equivalence.

Einstein proved how space and time behave in his special relativity and he later proved how gravity works in his famous General relativity.

In general relativity he also proved how gravity affects space and time.

We will talk about general relativity in our next post. General relativity is quite large to be understand, so we will talk about it in many posts.
