Thank you for the greeting.
So your idea is that those galaxies will make it to our location without acceleration? But the problem states that their speed is proportional to the distance; therefore, the speed will change according to time t and that is where acceleration come from.
oh sorry; I'm a newbie. Firstly, i think that if the velocity is proportional with distance so there's must be a acceleration around here. Then, I calculate that acceleration by the equation: vt^2 - v0^2 = 2as. Next, by using the equation:
delta(x) = v0x.t + (a.t^2)/2 with v0x=0 and the...
It has been found that, on average; galaxies are moving away from Earth at a speed that is propotional to their distance from Earth and that speed is called: Recessional Speed. Recessional speed v of a galaxy a distancce r from Earth is given by v = H.r;
where H = 1.58e-18 (1/s) is called...
