Cool!
As-tu déjà une idée de la distance qui aurait pu être atteinte?!
En redshift, j'imagine qu'il s'agit de z=9 ou z=10 maxi.
Ce qui correspond pour z = 9:
For Ho = 71, OmegaM = 0.270, Omegavac = 0.730, z = 9.000
It is now 13.666 Gyr since the Big Bang.
The age at redshift z was 0.556 Gyr.
The light travel time was 13.110 Gyr.
The comoving radial distance, which goes into Hubble's law, is 9421.4 Mpc or 30.729 Gly.
The comoving volume within redshift z is 3502.712 Gpc3.
The angular size distance DA is 942.1 Mpc or 3.0727 Gly.
This gives a scale of 4.567 kpc/".
The luminosity distance DL is 94207.9 Mpc or 307.268 Gly.
1 Gly = 1,000,000,000 light years or 9.461*1026 cm.
1 Gyr = 1,000,000,000 years.
1 Mpc = 1,000,000 parsecs = 3.08568*1024 cm, or 3,261,566 light years.
et z = 10
