Black Holes - An Exotic Yet Menacing Mystery

 


The entire concept of Black Holes is puzzling yet quite intriguing mystery. Their entire entity contradicts many and most scientific laws. As if, physical laws cease to exist inside them at all. This mystery has puzzled many scientists however, they are still studying them in order to know more about them. Many discoveries have been made since their initial recognition. 

 

Historical Background

 Their initial characterization was evaluated by Karl Schwarzschild in 1916 whereas, their initial interpretation of 'regional spaces from where nothing can escape' was first presented by David Finkelstein in 1958. Their evaluation was evaluated through Einstein's 'General Theory of Relativity', the theory greatly helped scientists understand their existence and properties. Studies were, and still are, conducted so that they could be understood. All the studies led to the following definition of Black Holes :

Black Holes are regions of spacetime where the gravitational force is so strong that nothing can escape from it's surrounding, not even light rays or even electromagnetic waves/rays. Nothing can escape it's grasp. 

Present Understanding

Originally, according to the theory of relativity 'a sufficient compact mass can deform spacetime to form a Black  Hole'.

All the study that had been done till recent was based on assumptions and estimations. The scientists could view far away Black Holes but couldn't present it in a photographic format. This was the case until 10th April, 2019. That day the world was presented with something unprecedented, that was the first-ever photograph of a Super Massive Black Hole (SMBH). The photo was a huge scientific achievement that was done with the help of hundreds of scientists around the world. This was a massive project and required a lot of time, effort and money. The picture revealed is as follows:
 
 
The photo's focus was not very sharp due to the sheer distance of the black hole from the Earth. A simulated photo of a black hole is given as follows:
 
 
Black Holes comprise of different sections regarding their entire physical body. Some include :

The Accretion Disk

An accretion disk is a structure formed by diffuse material in orbital motion around a massive central body. The central body is typically a star. Friction causes orbiting material in the disk to spiral inward towards the central body. (Source : Wikipedia)

The Singularity 

The Black Holes, in their center, consist of a puzzling dark void called the Singularity.

The Event Horizon

The 'event horizon' the boundary definition of a Black Hole, it defines the region from where not even light can escape from; i.e, the escape velocity exceeds the speed of light.




Overall, there's a lot to Black Holes and they still are, to a major extent, a mystery that has yet to be completely unfolded.

I hope you got to learn something new from this blog and for further research and study you can visit the site COSMOS (https://astronomy.swin.edu.au/cosmos/). If there are questions or any type of suggestions you would like to ask or recommend, then you can do so by commenting down in the comments. That is all from me today.

Free Of Cost Software For 3-D Animation

 



 The art and use of 3-D animation has increased tremendously in the recent years. The versatility provided by it is the main reason for its popularity. 3-D animation is the process of creating three dimensional graphic photos in a series through specific programs. The flow created by the photos is viewed as animation. However, learning the craft of 3-D animation is not an easy task to learn and master. The main problem being, which software to use. To help ease that task here are some highly recommended free software used for 3-D animation : 

1. Blender : 

 Blender is a free professional open-source 3D animation and modeling software. It is used in a host of applications ranging from animated feature films, visual effects, art, interactive applications, video games, and architectural visualizations. This free 3D animation software’s dizzying features set includes 3D modeling, UV unwrapping, texturing, raster graphics editing, rigging, and skinning, fluid and smoke simulation, particle simulation, soft body simulation, sculpting, rendering, video editing, and compositing.

2.Daz3D:

Daz3D is a 3D animation software that is primarily gear towards hobbyists. That means this tool takes some short cuts to ease the workflow. You can either buy a ready model on the market place that appeals to you. Alternatively, you start with one of the preset models and modify it to your liking. Like similar programs, Daz3D has a host of tools to tweak every aspect of the base models, such as the build, size, and length of limbs. Once you are done styling it with a hair cut, and clothing your creation, you can set up complex scenes with items from a large library of props that covers many genres.

 3.MakeHuman:

 MakeHuman is a free character creation tool that grew out of a Blender plugin. Users generate realistic 3D models of humanoid characters using sliders that control general properties like age, gender, and weight, down to the intricate features like the shape of the face or the length of limbs. The developers of this free 3D animation software pride themselves on 12 years of research in body topology resulting in a robust and variable base mesh that is optimized for processing in other tools like Mudbox or ZBrush. Cloth your 3D character with a variety of garments that will add additional realism.

 4.Mixamo:

 Mixamo is an online platform that has the potential to speed up the 3D animation workflow by creating rigs for bipedal characters automatically. Setting up a skeleton manually can be a painful process, as the weights for each bone have to be painted piecemeal. In this 3D animation software, users upload their 3D files and mark some key elements like knees and elbows. Then, Mixamo does its magic and creates a sophisticated skinned and weighted rig that is ready for 3D animation.

5.  SmartBody:

 SmartBody is a free 3D animation software for 3D characters. Both keyframe animation and motion capture are accepted as input sources. At its core, SmartBody features a set of comprehensive 3D animation tools that work in real-time. Among them are locomotion, steering, object manipulation, lip-syncing, gazing, nonverbal behavior, and retargeting. This allows your characters to pick up, touch, or place objects in the environment, automatic facial animation based on audio input, and much more. A feature set like this is usually found in commercial products costing hundreds of dollars.

6.  Boats Animator:

 Boats Animator is a free stop motion animation software that is published open-source. It stands out by its clear and uncluttered user interface that lowers the entry barrier to animation to accommodate even beginners. But it is comprehensive enough to appeal to experienced animators. Most importantly, this 3D animation software features onion skinning – the program displays the last image captured on top of the live feed from your camera. This assists you in creating smooth animations since you can accurately move your model in position for the next frame.

 7. Pencil2D:

 Pencil2D is a free and open-source 2D animation software for use in traditional hand-drawn animation. Users can choose between two basic styles of 2D animation: bitmap and vector graphics. While bitmaps can be drawn quicker and according to many artists appear to look more natural, vector graphics have the advantage that mistakes can be fixed easily by pulling the vector line into the desired shape. Both approaches can be combined in the same scene, as they are assigned separate layers. The sketching tools work in harmony with tablets and pens. However, don’t be alarmed that not every tool works on both kinds of layers.
