Science has discovered the “God spot” in people’s brains. Ecclesiates says that God “has put eternity into our foreheads”. Coincidence? Or a true intersection of science and theology....?

Impossible. You cannot change “settled science.”

I personally can’t understand how the Standard Model of cosmology manages to continue to be taken seriously after the amount of contradictory evidence that continues to pile up on top of it.

The truth is clearly elsewhere, even if we don’t know what that truth is yet. But we won’t get to the truth following a known-false path.

Wow! I’ve seen that before!

Every night, in fact when I take my glasses off outdoors. I’m extremely nearsighted.

True on all accounts.

And, the girl you were traveling to visit in that distant galaxy might already be an old woman, so you might have to take her granddaughter on that date instead.

Developing the technology to cross the oceans of space to other worlds would probably work out as well as when different cultures on earth developed the technology to cross the seas and oceans separating the continents.

That is to say it will likely be another cultural disaster like the one unfolding around the world today.

Perhaps the creator put us on different continents and in different galaxies separated by great distances for a reason.

OTOH - It could just be an 18 wheeler barrelling down a two lane highway right at you.

Maybe it’s because a lot of religionists favor Big Bang cosmology.

There is variability in the speed of accretion.

Given that difference and the variability of galactic matter distance and density, there is no constant rate of black hole formation.

Nothing ruins your day like a massive galaxy pile-up. I was stuck behind one for hours once.

How long did the light take to get here from this cluster, which is 12 bil LY away?

Is that a trick question?

How old is the universe per them?

How far away is this cluster, per them?

That brings a tangential question to mind: If warp drive someday becomes possible (or fictionally, in the world of Star Trek), how could ships using it navigate over extreme distances when the observed nature and location (or even the very existence) of various stars, planets, galaxies, etc. could be completely different than what was observed via light emanating from them that presented a picture that was millions or billions of years “out of date?” That planet that you’re heading for a million light years in the distance might not even exist anymore, or that star that it appears to be orbiting might actually now be a supernova, presenting a very nasty surprise upon arrival.

Depends upon how far you travel. If you are only looking at travelling within our own galaxy (Star Trek takes place almost entirely within our arm of the Milky Way.) If you're not travelling more than a few thousand light years, or even a few tens of thousands, the motion of the stars is well known and can be calculated even by today's computers. Now, if you're going tp be dealing with the entire galaxy, which contains a few hundred million stars, it's still pretty straightforward, as all you really need is a good map of the star's actual positions. Making such a map would be pretty easy if you've got warp drive, and can make observations from widely distant locations. A database of absolute locations and trajectories would be a few gigabytes of data, and again is something that can actually be handled by modern computers.

If you've got the juice to travel a really long way, like other galaxies, the problem becomes larger, as the distance means more light-delay of observations. Again though, it's all just a matter of compute power.

If you'd like to play with a really cool program for visualizing the issues, you might download a copy of Celestia. There are free versions for Linux, OSX, and Windows. If you play with that program for a while, and consider the speeds necessary to go anywhere, you will get a partial grasp at how freaking huge just this galaxy is. As an example, I plotted a course to Alpha Centauri, the closest star other than the Sun. Travelling at 1 AU/sec, that is, covering the distance between the sun and earth every second, it will still take weeks to get there.

For fun, you might check out this which is a webpage I put together on my personal website of rather fanciful possibilities of things to be discovered with Celestia

Why is it when there’s an unexpected astronomical observation that every FReeper with crackpot beliefs about cosmology somehow think their beliefs are now the absolute truth?


Well, it’s just a theory, but maybe they are impelled to discredit science, even though we’re soaking in it, because it is a barrier to believing in their mind-reading invisible man in the sky.

Tell your wife to keep her bra away from your face. That should do it.

I wish ... if that was really happening she would rarely be wearing that bra.
