Hi,
Is it posible for us to determine the velocity of our sun?
The Hubble constant gives a referent for the exspansion of the universe but do we have any way of knowing if the point at the centre of the big bang was, (or is), stationary?
Do we know in which direction the centre of our universe was, (or is)?
I understand that we go through a very complex series of motions here on Earth, orbits round our sun, sun orbits galaxy, galaxy orbits other galaxies and on. So I appreciate that putting this in anything other than purely circumstantial language might be a bridge too far. but what is know of this?
In an expanding universe, I can understand the doppler shift of light in one direction due to the overlay of motion causing an increase in frequency, (please correct me if I am wrong), but a reduction in frequency would suggest motion opposing expansion.
Is this considdered to be a result of relative motion due to celestial dynamics?
Any help is greatly appreciated.
John
