History of our Universe: To know the history of our Universe we have to go back in time, 13.7 billion years back. ![]() So, let’s delve deeper and find out what is really being said here. Thus you see this is worthy of something that should be pursued further. Now if we are to believe that our Universe is a giant hologram, then it would mean that our objective reality is nothing but an illusion! If true, it would bring a paradigm shift in the perception of our Universe. On the other hand hologram in our daily life is a piece of 2-dimensional sticker inside which a 3-dimensional image appears to be embedded in. Wow! that is quite dramatic!Īlmost all the objects we see around us are 3-dimensional, means they have length, breadth and height. ![]() But the puzzling thing is that the better model appears to be a model which envisage our Universe to be a hologram. What does this result really mean to a common person? Well, if we try to decipher it then we find, one set of model is found to be better than the other type of model to explain some data on the properties of our Universe. A Few years back a paper in the prestigious Physical Review Letters (see here) has claimed that they found a holographic model of our Universe can explain the data on Cosmic Microwave Background Radiation (CMBR) better than the standard cold dark matter model of cosmology (Lambda-CDM model).
