What randomness does not explain is why we would have a sense of it being a perfect explanation?
The most common explanation for the formation of planet Earth is that it formed by gravitational collapse from a cloud of particles (gas, ice, dust) swirling around the Sun. Specifically, the idea is that small planetesimals form as the various particles clump together (perhaps initially by cohesion, then by gravity), eventually growing into planets. Known Read More…
Slightly off topic from the regular fare, but firmly in the ‘cool science stuff’ category. Photo of the partial eclipse this afternoon, taken in front of our house, with massive sunspot region 12192 visible near center: Equipment: Panasonic DMC-ZS3 with a Starmax 127EQ telescope and solar filter. Also required: patience. I’m pretty happy with how Read More…
Having read the recent post here on where Earth’s water came from, I just stumbled across an interesting article over at ExtremeTech.com from June of this year, evidently commenting on a find that was originally reported in Science (at least, that’s what I’ve gathered from reading a bit about it elsewhere). I’m not sure if anything came Read More…
If it is interstellar, it means that our galaxy is chock full of water, and then every other planetary system that we’ve spotted could easily have water in it.
Pop culture rants, raves, and peeves have somehow found their expression today as “science.” This stuff doesn’t change; it just acquires science labels.
The Milky Way is part of a supercluster called Laniakea, it seems
More interesting than secularist myth.
This weekend, the Apollo 11 Moon Landing happened forty-five years ago to day and date. Video: [youtube lRwKUScppvQ] I remember sitting on the stone ledge of our patio after church on Sunday, July 20, 1969 sipping a drink as radio carried the story of the Apollo 11 Moon landing. Then, that evening my Dad tuned Read More…
David Weinberg: at least one thing we thought we knew about the present day universe isn’t true.
Something they possibly wouldn’t have done if the US had a viable space program as opposed to airy fairy theories about the multiverse.
NASA astronomers clearly very much want to believe so. But in wake of cosmic dust flap. caution is advised.
Sounds like somebody’s baby. Who’s your daddy?
We can draw reasonable conclusions from what we now know or continue to speculate.
Good news: No one has so far suggested that the simple explanation is that they are left over from the universe that predated this one.
