According to some futurists, humans will be able to upload their consciousness to computers in the near future. They say that humans will achieve digital immortality by uploading their Minds to computers. This process is also known by various other names like - Whole Brain Emulation (WBE), Brain Upload, Mind Upload, Mind Copying or Mind Transfer. So what this brain upload actually is - It is the hypothetical futuristic process of scanning the mental state of a particular brain substrate and copying it to a computer. This mental state includes long term memory and “self”.

Then a simulation model of the brain's information processing could be run by the computer, such that it responds in essentially the same way as the original brain and experiences having a conscious mind. Martine Rothblatt- A lawyer, author, entrepreneur and CEO of biotech company United therapeutics Corp. Says - “the purpose of biotechnology is the end of the death" Rothblatt introduced the concept of "mindclones"- that are the Digital versions of humans that can live forever. She explains how the mind clones are created from a "mindfile", a sort of online repository of our personalities. This mindfile would be run on "mindware" a kind of software for consciousness. Physicist Roger Penrose of the University of Oxford and others disagree with the interpretation of brain as a mere computer. According to Penrose, consciousness is a quantum mechanical phenomena arising from the fabric of the universe. So uploading the brain would have to involve quantum computers.

Here we will discuss 4 different theories, that tells how our beautiful universe will be destroyed eventually. As we know, nothing will last forever in this universe, not even the universe itself. The 4 theories about the end of the universe that we are going to discuss here are-
End of the Universe Theories
1.The Big Freeze (Heat Death) 2.The Big Rip 3.The Big Crunch & 4.The Big Bounce Now we will discuss each of these theories about how the universe will end one by one-
End of the Universe Video
1.The Big Freeze (Heat Death) Theory
Actually the fate of the universe is determined by its density. This scenario, in combination with the big rip scenario, is currently considered as the most important hypothesis. According to the big freeze theory, continued expansion of the universe would result in a universe that would eventually approach absolute zero temperature. In this scenario, stars are expected to form normally for 10^12 to 10^14 years, i.e. for 1 to 100 trillion years, but eventually the supply of gas needed for the formation of stars will be exhausted. The existing stars will cease to shine as they will run out of fuel. This will cause the universe to grow darker and darker with time. These dying stars will eventually turn into black holes and our universe will be dominated by these black holes. The black holes also will not survive for infinite time as they emit Hawking radiation. A Related scenario is the heat death. According to it, the universe goes to a state of maximum entropy, in which everything is evenly distributed, there are no gradients- which are needed to sustain information processing, one form of which is the life.
2.The Big Rip Theory
According to the big rip theory, the universe expands so fast that the gravitational force of attraction cannot compensate it and tears it apart. If the density of dark energy increases with time, it will cause the rate of acceleration of the universe to increase. It will lead to a steady increase in the Hubble constant. As a result, eventually all the matter present in the universe will disintegrate into unbound elementary particles and radiation. As the dark energy density and the expansion rate of the universe becomes infinite, the end state of the universe will be a singularity.
3.The Big Crunch Theory
The big crunch hypothesis states that, the universe will not continue to expand forever. This Theory assumes that the average density of the universe will be enough to stop its expansion and it will start to contract. Because of This continued contraction, all the matter and spacetime in the universe would collapse Into a dimensionless singularity. This is the reason why it is named as the big crunch. At this stage, the universe will be at a point from where it started- The Big bang. This scenario allows the big bang to occur immediately after the big crunch of a preceding universe. If this happens repeatedly, it creates a cyclic model. This cyclic model of the universe is also known as an oscillatory universe. Theoretically, the cyclic Universe could not be reconciled with the second law of thermodynamics: Entropy would build up from oscillation to oscillation and cause heat death. According to current evidences, the universe is not closed. This has caused the cosmologists to abandon the oscillating universe model.
4.The Big Bounce Theory
According to the Big Bounce hypothesis, the universe will continuously repeat the cycle of a big bang, followed up with a big crunch. So the big Bounce is a hypothetical cosmological model for the origin of the known universe. The big Bounce theory assumes the big bang as the beginning of a period of expansion which is followed by a period of contraction. So the big Bounce means, the big crunch followed by the big bang. It is really exciting to think that we could be living at any point in an infinite sequence of universes or conversely, the current Universe could be the very first iteration. So That is all for now, about the theories, that suggest the fate of our universe.

Do you know that human brain is not just the most complicated part in our body but it is more complex than any other known structure in the whole universe. Our brain can process enormous amount of information in a fraction of second. It has been proved by researchers that Human brain is much more powerful than any supercomputer made by us. So let's see Some mind blowing facts about our brain that you will find really hard to believe !!!
Facts about Human Brain Video
1. The brain itself cannot feel pain as it has no pain receptors. This is the reason why brain surgery can be performed while the patient is awake without any discomfort or pain. 2. There are about 1 billion neurons in the human brain. Each neuron forms about 1000 connections to other neurons, that results in more than a trillion connections. 3. Do you want to know the storage capacity of human brain? So let me tell you that the Storage capacity of the human brain would be enough to hold nearly 3 million hours of TV shows!!!. In other words, we can say, if our brain worked like a digital video recorder in a television, then to completely use that storage you need to leave the TV running continuously for more than 300 years. So your brain would never run out of space at least in your lifetime. 4.Our brain is mostly made up of water. 73% of our brain is nothing but water.
5. Weight of an adult brain is about 3.3 pounds I.e. 1.5 kilograms. Average Male has a brain volume of 1274 cubic centimeters, while that of female brain is 1131 cubic centimeter and it makes up about 2 percent of our total body weight. 6. A very small piece of brain tissue equivalent to the size of a grain of sand contains nearly 100,000 neurons and 1 billion synapses and these all communicate with each other. 7. Do you know that our brain needs constant supply of oxygen. Some brain cells may die in the absence of oxygen for as little as five minutes. 8. Human brain uses 20% of body's total energy and oxygen intake although it is only 2% of the total body weight. 9. You will find it interesting that, our brain contains different types of cells. 10,000 specific types of neurons are present in the brain. 10. Do you know that human brain reaches its full maturity at the age of 25. Now you can understand, why your teenage kids sometimes behave so immaturely. 11. It's been found that our brain can generate up to 50,000 Thoughts per day, that's why it is also called as a "random thought generator". 12. Processing of information in our brain is extremely fast. It can process an image that our eyes have seen just for 13 milliseconds.
13. You will be Surprised to know that our brain generates about 12 to 25 Watts of electricity which is enough to power a low wattage LED light. 14. Weight of Albert Einstein's brain was 10% less than that of the average brain but the neuron density of his brain was greater than of average human brain. 15. It has been found that a part of brain known as hippocampus is significantly larger in London cab drivers. Hippocampus is considered the memory centre of our brain. But why London cab drivers have larger hippocampus? The reason behind this is, they need to navigate through 25,000 streets of London which gives their brains great mental workout specially memory part. So now you can understand, why mental exercises are necessary to keep our brains sharp. 16. Our brain cannot concentrate on two things at the same time, all it can do is to switch quickly between different tasks which gives the illusion of multitasking. So friends these were some unbelievable facts about human brain.

According to physicists time is not real, it is just an illusion. There is no past, present or future, they all exist together. It means everything happens at the same time. Actually the concept of time is simply an illusion made up of human memories. Massachusetts Institute of Technology physicist Max Tegmark, told space.com: "we can portray our reality as either a three dimensional place where stuff happens over time, or as a four dimensional place where nothing happens i.e. a block universe- and if it really is the second picture, then change really is an illusion, because there is nothing that is changing; it's all just there - past, present, future.
Time is an illusion Video
“we have the illusion, at any given moment, that the past already happened and the future doesn't yet exist, and that things are changing. "But all I am ever aware of is my brain state right now. The only reason I feel like I have a past is that my brain contains memories." According to the block Universe theory, the universe is a giant block of all the things that ever happen at any time and at any place. On the basis of this block Universe model, past, present and future are not separate, they all are present at the same time. According to this model, every moment of our life is out there, somewhere in space-time. Our birth and death moments both coexist at the same time, somewhere in space time coordinates. So according to the block Universe theory, it is possible to time travel. But it says that passing of time is just an illusion. Nothing is changing in our universe. Every event that has happened from the beginning of the universe, any event that we are observing right now and any event that will happen in the future, is already present at certain coordinates in the block Universe. So passing of time is not real, it is an illusion that we observe because of our memory of the past. Nothing is passing, everything is already there somewhere in space time. To make this idea easy to understand, let me give you a simple example. When we watch a recorded video on our mobile phone, then we see, things are happening in a sequence as the time passes in the video. Let me ask you... whatever you are seeing in the video is happening in real time? You will Say, no... Because you are just watching events that have already happened. You are just seeing the recorded events in the past. The whole story told in the video, has already been told. You can go to any point in the video by reversing and forwarding it. The whole story is already present in the recorded form in the memory of mobile. But whenever anyone watches this video from starting to end, he or she feels like events are taking place in the real time and they enjoy it. But nothing is happening at that time. Everything has already happened. In the same way, according to the block Universe model, everything that has happened, is happening and will happen, is already present at the same time in the universe at some point in space time. We are moving from past to present and from present to future with time, is just an illusion of our brains. So time is an illusion!!! So friends, You can share your ideas and questions regarding, what is time, in the comment section. Do you agree with the block Universe theory? Do you really think that time is an illusion. Share with others your point of view about the time.
