LOG#208. Monsters and LISA.

Black holes and other astrophysical objects are true monsters. Some interesting tools from web pages to learn about these free catalogues: WATCHDOG and BLACKCAT. Also, the blackhole.org page and the sounds of spacetime for gravitational waves are suitable for you. … Continue reading

LOG#207. Beck, Zeldovich and maximal acceleration: the vacuum.

Some time ago, Zeldovich derived the following expression for the vacuum energy density: (1)   or equivalently, with a link to Caianiello’s maximal acceleration formula, (2)   Remark: the above vacuum energy density is related to the cosmological constant via … Continue reading

LOG#206. Multitemporal theories.

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

LOG#205. Ether wind, SR and light clocks.

From the Michelson-Morley experiment, some clever experimentalist tried to derive the light speed through the “ether wind”. It is very similar to a river being rowing by sailors in a boat. The times for journey “upstream” and “downstream” are:   … Continue reading

LOG#204. Mechanics and light.

Gravitational or electrical forces are inverse squared laws:         Strikingly similar, they are both also conservative forces. For gravity:     and     for the electrical force. Defining the potentials , and , you get the … Continue reading

LOG#203. Action gym.

A challenge post! 😉 Quantum physics becomes important when the magnitude called action is of order of Planck constant (an action itself!). Action is quantized. It is a much more essential quantization than that of energy or angular momentum (action … Continue reading

LOG#202. Harmonic oscillator.

Some clever physicists say that everything is an harmonic oscillator, and that every hard problem is just solvable in terms of a suitable set of harmonic oscillators (even true with string theory!): In classical mechanics (CM) you have a the … Continue reading

LOG#201. Generalized absement.

Absement is generally defined as (1)   We can even integrate the absement -times (position integrated -times) to get (2)   i.e. (3)   with dimensions of and units of . However, if time is multidimensional, and the time vector … Continue reading

LOG#200. TSOR: The Spectrum Of Relativity.

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

LOG#199. M-sigma.

Black holes are coming! No, winter is coming! NOOOO! Winter is here, and black holes, as shown by LIGO, are not coming. They are already here, as they were already supposed to exist due to X-ray astronomy. Moreover, LIGO-VIRGO, LISA, … Continue reading
