Would the greatest voids in the universe support Hubble's law to a substantially lesser radius than the neighborhoods of galaxies?
Well, yes, I would tend to think that Hubble's law would apply at smaller distances in the absence of strong gravitational wells. My reasoning is thus:Loren Booda said:Would the greatest voids in the universe support Hubble's law to a substantially lesser radius than the neighborhoods of galaxies?
It doesn't really matter how the universe expands, as long as it expands, and the peculiar velocities tend to damp themselves out. So yes, it works in the presence of a cosmological constant. Or without one.Loren Booda said:Chalnoth,
What would the Hubble effect have on damping matter which undergoes "cosmological constant" acceleration? Without gravitational interaction, would large z bodies still tend towards damping's "self-fulfilling prophesy" of eradicating peculiar velocities (or perhaps peculiar accelerations)?
Hubble's Law states that galaxies are moving away from each other at a rate proportional to their distance. This means that the universe is expanding, and the further away a galaxy is, the faster it is moving away from us. This is evidence for the Big Bang theory and suggests that the universe is still expanding.
Voids are large, empty regions of space that contain very few galaxies. They can range in size from a few million to a few hundred million light years across. These voids can have an impact on galaxies by causing them to move towards or away from each other due to the gravitational pull of the surrounding matter. The presence of voids also affects the distribution and evolution of galaxies in the universe.
Scientists use data from telescopes, such as the Hubble Space Telescope, to map out the large-scale structure of the universe. By observing the distribution of galaxies and their velocities, they can identify regions with low galaxy density and classify them as voids. They also use computer simulations to model the formation and evolution of voids in the universe.
The study of voids in the universe provides valuable insight into the large-scale structure and evolution of the universe. It also helps us understand the distribution of matter and dark matter, as well as the effects of dark energy on the expansion of the universe. Voids also play a crucial role in the formation and evolution of galaxies, and studying them can help us better understand these processes.
Yes, there are ongoing studies and future projects focused on exploring Hubble's Law and voids in the universe. For example, the Dark Energy Survey and the Large Synoptic Survey Telescope are both projects aimed at mapping the universe and studying its expansion. The upcoming James Webb Space Telescope will also provide new data and insights into the structure and evolution of the universe, including the study of voids.
