AI Thread Summary
Hubble's law states that the velocity of recession of galaxies is directly proportional to their distance, expressed as v=H0.r. However, the theory of relativity introduces time dilation, which suggests that as the velocity approaches the speed of light, time effectively slows down to zero. This implies that the universe may expand only up to a certain distance, approximately 2 x 10^10 light-years, beyond which galaxies would appear to slow down relative to an observer. The discussion raises concerns about the implications of galaxies exceeding the speed of light, as this would lead to complex values for gamma in relativity. Ultimately, the relationship between galaxy recession and relativistic effects suggests a limit to the observable universe's expansion.

According to Hubble's law, Velocity of recession of galaxies is directily proportinal to distance between them

ie v=H0.r

But, according to theory of relativity

Time diliation

t=t0.(underoot 1-v^2/c^2)

as v->c

t=0

That means the universe will expand upto a certain distance ( if the law hold correct) i.e 2.10^10 l.y

After that the galaxies will slow down to the observer

Here i don't think its possible that v>c.Also if it were to be so you would get \gamma as a complex number!
 
I meant as v is almost equal to speed of light, will the recession of galaxies slow down? because t~0
 
Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...
3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
