What is dark energy? Where does it come from? Is it constant? Is it a quantum field? Is it vacuum energy? Nobody knows what is the 70% of the Universe! In the beginning of Physics as Science, Aristotle himself introduced … Continue reading
Newton’s gravity reads: In extra dimensions, , , it reads For extra dimensions, if their size are much smaller than considered distances, , then by matching So, gravitational is weak in our … Continue reading
Happy New Year 2018, dear followers! Today is a special blog post! My 200th post! After a really terrible 2017 from the viewpoint of family, health and productivity, I wish this one will be a great year for me and … Continue reading
The marriage between gravity and quantum mechanics is “complicated”. The best physicists and brightest minds have tried, but only with partial success. String/superstring theory, now M-theory, is a curious story. The another story is canonical quantum gravity, or loop quantum … Continue reading
The year 2013 is coming to its end…And I have a final gift for you. An impossible post! This year was the Bohr model 100th anniversary. I have talked about this subject already, here, here and here. The hydrogen spectrum is very important in … Continue reading
In 1905, one of Einstein’s achievements was to establish the theory of Special Relativity from 2 single postulates and correctly deduce their physical consequences (some of them time later). The essence of Special Relativity, as we have seen, is that … Continue reading
TABLE OF CONTENTS CENTENARY BLOG POST! And dedicatories… 1. Serendipitous thoughts about my 100th blog post 2. The search for unification and higher dimensional theories 3. Final relativity 4.

In the next group theory threads we are going to study the relationship between Special Relativity, electromagnetic fields and the complex group . There is a close interdependence of the following three concepts: The classical electromagnetic fields and can be … Continue reading
Imagine that an idealised bug of negligible dimensions is hiding at the end of a hole of length L. A rivet has a shaft length of . Clearly the bug is “safe” when the rivet head is flush to the … Continue reading
The Batmobile “fake paradox” helps us to understand Special Relativity a little bit. This problem consists in the next experiment: There are two observers. Alfred, the external observer, and Batman moving with his Batmobile. Now, we will suppose that the … Continue reading
