In this video I explain the Hubble constant and the age of the universe.

Well presented. Fascinating. Bravo

Sir what is the probable end for the universe if any would be?

[@0219-n1e]

So according to this scenario can we deduct that the universe expansion would not be the end of the universe. as suggested?

[@MichelvanBiezen]

The expansion of the universe will probably go on forever.

[@omsingharjit]

if Hc is known . Then how did Astronomers find that Value ??

[@MichelvanBiezen]

By determining the receding velocities of galaxies and then observing Cepheid variable stars and type 1A supernovas to confirm the distance to those galaxies.

Doesn't make sense. All the galaxies have a magnetic signature [discovered by the Voyager(s) space craft.] If they all have the same sign (- +) then they "should" be moving apart. No need for an expanding Universe, Dark Matter or Dark Energy. The attraction (Gravitational Anomaly) That is pulling our galaxy and 100000 others {Shapely Super Cluster} may just be an opposite magnetic sign (+,-). As those galaxies get closer to the opposite field then they should accelerate. If the wavelength changes through different intensities it doesn't mean the universe is pulling different (new) space out of another dimension. Someone should give your wife (?) a microphone~ can't hear her questions. Tks. Tracing the galaxies back to day one does not give a point of occurrence.
