The Hubble Telescope snapped the object named Arp 282, which is an interacting galaxy pair composed of the Seyfert galaxy NGC 169 & the galaxy IC 1559. In ESA's own words, this incredible three-dimensional-looking picture by Hubble shows two galaxies interacting with each other as if engaging in a 'cosmic draw'. The interaction captured by the telescope is considered significant as astronomers believe that the interaction of galaxies with one another is an important aspect of their evolution. According to ESA, the object seen in the picture is named Arp 282, which is an interacting galaxy pair composed of the Seyfert galaxy NGC 169, seen at the bottom, and the galaxy IC 1559 at the top. Both the individual galaxies are said to have monumentally energetic cores, known as active galactic nuclei (AGN), although they are not visible in the picture.

That could disturb the Oort Cloud.
Rare because not many of them have been seen so far. But program an AI to inspect and sort trillions of dots in billions of photos and you might be right, there could be an infinite amount of galaxy pairs like this in an infinite universe.
Psalm 19:1
The heavens declare the glory of God; and the firmament sheweth his handywork.
Amen
Might take a while - I've only got a weekend to travel...
With a little effort and a TI calculator, maybe you can get some clue to the answer using Albert's equation to solve for the appropriate metric tensor:
Rμν - 1/2gμνR + gμνΛ = 8 π G/c4Tμν
Where:
Rμν==>Ricci Tensor (Derived from Riemann Tensor)
g==>Metric Tensor
R==>Ricci Curvature Scalar (Derived from Ricci Tensor)
Λ==>lambda = Universal Constant (Expansion/Dark Energy)
π ==> PI (8 decimal places is OK)...
G==>Gravitational Constant
c==>Speed of Light
T==>Stress-Energy Momentum Tensor 😲
Rμν - 1/2gμνR + gμνΛ = 8 π G/c4Tμν
Thanks but I already have and it doesn't add up.....
It is ancient history.
It is imagery such as this which gives me pause as to the accuracy of the formulae for arriving at the number of Earth-like planets in the universe.
I have always believed that the number is exponentially high, and that Earth is exceedingly rare.
The reasons ought to be patently obvious but, then again, even some FReepers believe a journey and habitation of Mars is survivable today.
