Astronomy Q&A

[Halcyon Dayz]

Wegener literally died for science. He is a hero.
But when it comes to geology, he was a woo-woo who accidentally
happened to be (somewhat) right.
Continental drift is now accepted because we can see the continents
drifting. We also have a mechanism to explain it.
With all the thousands of crazy ideas going around, some of them are
bound to be close to the truth. But we only are going to know if we
have data to support these ideas.

From Wiki on Louis Pasteur:
"His experiments confirmed the germ theory of disease."
(Emphasis mine.) Pasteur gathered evidence that proved an idea.
Ideas alone isn't science, and doesn't get us any closer to the truth.

BTW, it was Antonie van Leeuwenhoek who thought us about bacteria.
He did that by observing them, as could anybody else with a microscope.

You are young, think you have knowledge you not given yet.
Anton more concerned with his lenses, you dug your own hole,
Pasteur did more than accept Antons observations of a microscope,
And Anton was very good in making lenses for microscopes. History
records it. Pasteur followed that up by showing a relationship between
bacteria and human health, Anton not concerned, his lenses showed
the bacteria, what they represented was not his concern.
Halcyon, if you want to succeed, you must evaluate better.
Science driven by reason and logic is one thing. Science driven by
hormones, is doomed to failure.

Care to repeat that in English?

[Nokton]

Yes, Halcyon, your grasp of concepts is confined by your age.
You make a great play of understanding and knowing.
Tell us what you are about. Do you conceive and understand
life, do you have any explanation of it? Think not, some in here do.
So in reason and logic, tell me your thoughts on crop circles....

Guys, please, this is Astronomy Q&A, not crop-circle Q&A.

Hi Guys,

Moved to Chit Chat forum under new thread called Crop Circles.

Ok, lets twist our brains a little with this strange question that came to my mind.......

Let's say (of course I know it is totally impossible by the way) that the planet Earth suddenly doubled its size.

What affects or changes would this cause? Not only on the Earth but the Moon etc.?

That's a whopper of a question. Honestly it's probably way over all of our heads, I can't do the math required for finding out gravitational differences, and I could only give you guesses as to what would happen.

Drop it in at BAUT for the scientific answers would be my suggestion. I would do it for you but I left BAUT today.

One thing I do know for sure, evolution would have to work double time to figure out some interesting problems. For example: Bird Migration.

[The Mangler]

Would the mass have doubled as well? (That probably matters... )
If it did, I think that the moon would probably crash into Earth. I have no clue how fast that would happen though.

The mass would be quadrupled, to be exact.
