Calculations are presented from which the standard equations of motion of objects in expanding space, Hubble's law, are derived. Three independent approaches...

The proof of the vector nature of the gravitational potential is given, according to which the gravitational potential at any point in the infinite Universe ...

What does accelerated or decelerated expansion of the Universe mean? A definition of the concept of cosmological acceleration and an equation for its calcula...

People believe in miracles and love them. Although they say that miracles do not happen in the world, they are sometimes discovered where you would not expec...

Perhaps one of the most important observable parameters of all cosmological objects is the so-called red shift, on the basis of which the conclusion was made...

It is mistakenly believed that in a curved space, parallel transfer of a vector along a closed contour leads to a change in its direction. It is also erroneo...

Einstein based SRT on two principles. However, in order to obtain the Lorentz transformations and all the relativistic consequences from them, only one princ...

It is believed that in order to accelerate a spacecraft to high, even sub-light, speeds, significant reserves of fuel are required. However, the limited spee...
