Alan,
The lens of time, as Lee S put it, is also a benefit. The farther distance that we can see, the farther back in time that we can see. It means that we can look at galaxies soon after they formed after the big bang almost 14 billion years ago, and that is interesting, meaningful information. So, yes, 65 million years ago is not that long on the universe’s timeline, but it gives us additional meaningful data.

It may not affect the price of rice in Nice, but it helps to sate our curiosity about the universe, where we came from, and where we are going.

@ Alan….
We don’t have much choice…. If we want to study the universe, we must accept we do so through the lens of time.
Unless we have the rules of nature completely wrong, said rules were the same 65 million years ago as they are now .. so to say observations of distant astronomical objects and events mean nothing is nonsensical.

Is this serious? We are looking so far into the past, how ca we use this information? Near the center of the spiral galaxy NGC 3938, 65 million light-years away is NEARBY?!
ONE Light Year is 5,878,625,373,183.6 miles. That is about 5.88 trillion miles! What they saw happened 65 MILLION YEARS AGO and is so far away 65 million TIMES 5.88 trillion miles, nothing we observe at these mind bending distances means anything!

In reply to Will Smith. Will Smith: This was posted by me yesterday: Neutron star merger caused gravitational wave? You are not doing your homework and reading Behind the Black closely. :)

Bob did you saw this?
Gravitational waves spotted last year were created by merger of hyper-massive neutron star, scientists say
Researchers analyzed data from the LIGO and Virgo gravitational wave detector
The team initially thought the event led to the formation of a huge black hole
But, they instead found the two neutron stars merged to become one huge one.

In reply to Marcus Sammer. Marcus Sammer: Yup, from the point of view of astronomers, a galaxy only 65 million light years away is "nearby." Sounds strange, but when compared to the distances of most galaxies, in the billions of light years, this is practically next door.

I know space is big and nearby is relative, but referring to a star in another galaxy 65 million light-years away as a “nearby star” made me smile.
