Can objects in space appear to move backwards in time?

AI Thread Summary
In the discussion, it is clarified that an observer in space will not see another object moving backwards in time, but rather will perceive the other object's clock as running slower due to relativistic effects. Even if one object travels at 200,000 km/s and the other at 150,000 km/s, their relative speeds cannot exceed the speed of light, c. The observer will see the other object moving away at a speed less than c, with time dilation affecting their perception of the other object's clock. The addition of velocity theorem and time dilation theorem are relevant to understanding these observations. Ultimately, the principles of relativity dictate that no object can exceed the speed of light, maintaining consistent time perception for the observer.

Let's assume we have two "somethings" in space, they get away from each others. The speed of one of them is around 150,000kms/sec, very fast but less than the speed of light, the other one goes the totaly opposite way at 200,000kms/sec.

An observer on one of these would see the other element "going back in time" wouldn't he?

no, he would just se the other ones clock go slower than his own.
 
Wouldn't the observer see the other object flying away at the speed of light? No matter what the speeds of the two objects are their speeds can never add up to more than c, right? So his clock would be moving at normal speed and he would see the other object's clock either stop if it was receding at c, or moving extremely slowly if it was receding at less than that, correct?

Would this observer see the other object moving away at c or slightly less?
 
Use addition of velocity theorem and time dilation theorem.
 

Thread 'Matter density right after the decoupling'

https://en.wikipedia.org/wiki/Recombination_(cosmology) Was a matter density right after the decoupling low enough to consider the vacuum as the actual vacuum, and not the medium through which the light propagates with the speed lower than ##({\epsilon_0\mu_0})^{-1/2}##? I'm asking this in context of the calculation of the observable universe radius, where the time integral of the inverse of the scale factor is multiplied by the constant speed of light ##c##.

Thread 'Rutgers finds a transparent Einstein Cross - apparently a dark matter "halo".'

The formal paper is here. The Rutgers University news has published a story about an image being closely examined at their New Brunswick campus. Here is an excerpt: Computer modeling of the gravitational lens by Keeton and Eid showed that the four visible foreground galaxies causing the gravitational bending couldn’t explain the details of the five-image pattern. Only with the addition of a large, invisible mass, in this case, a dark matter halo, could the model match the observations...

Thread 'Hubble Constant, Dark Energy and the Expanding Universe'

Why was the Hubble constant assumed to be decreasing and slowing down (decelerating) the expansion rate of the Universe, while at the same time Dark Energy is presumably accelerating the expansion? And to thicken the plot. recent news from NASA indicates that the Hubble constant is now increasing. Can you clarify this enigma? Also., if the Hubble constant eventually decreases, why is there a lower limit to its value?
