Yes, I Googled the mass of the Andromeda galaxy and found the wikipedia page on andromeda with the stated mass which is how I based the approximate twice the size statement. I'm looking for further insight into other studies that focus on the mass of our own galaxy as it is the one that is under...
I just read this article on phys.org, and am now looking for any further insight into this. The article claims that the milky way may have approximately 210 billion solar masses of matter within 60,000 ly of the galactic center. If this is true, wouldn't that make the milky way nearly twice the...
Now this has raised the question of why such a telescope couldn't be positioned on the lunar poles to allow for observations, communications, and power? It wouldn't be ideal, but it would allow for a very large telescope.
Not sure if it was already mentioned, but Ceres does have the added benefit of having launch window periods at a little more than a year over Mars' 26 months. Launches can be done at nearly twice the frequency for Ceres, even if it is double the distance of Mars. No matter what, any current...
Showing the phases of the moon with a tennis ball and flashlight should make things clear about how the moon goes through its phases, and why it does so. Visibly showing that it HAS to go between the Earth and the Sun at some point.
This concept is entirely possible, if the atmosphere didn't get in your way to stop your projectile from reaching space without completely disintegrating. If the atmosphere were magically removed, yes the objects you launch can certainly get into space. As everyone said before, it wouldn't...
This makes me wonder if the two types of matter have any effect on each other upon falling into a black hole. But a black hole will still pull in the things around it as it is a gravitational phenomenon.
I would recommend the Arduino microcontrollers (Arduino Micro if you want a smaller version) and the Raspberry Pi. They're both great for simple projects and won't break your wallet. Each one has various ethernet, wi-fi, and bluetooth hardware that you can add for connecting together.
I'm not sure if we can consider them a collisional family with the data we currently have on Pluto. Perhaps in the future when we obtain more data from the New Horizons probe, we could verify whether or not they originated from a common object.
I was reading an article about the recent type Ia supernova in the big dipper when the question popped into my head that I've forgotten about until now.
Since we use the Ia supernova as our candles to measure the expansion of the universe, how do we know that everything is accelerating...
As was stated before, a finite quantity cannot become infinite. Your example shows that you can get as close to 1 as possible, but it will never be 1 BECAUSE it is infinite.
The is the exact same idea as the curvature of your circle. You can increase the size of the circle infinitely, and it...
I've been watching this thread all day and have become impatient at waiting for the last puzzle to be confirmed. So I'm posting this puzzle to see if anyone can solve it. (Be sure to make your guesses in spoiler tags!)
What is the next line in this series?
If the angle of incidence was possibly off in the experiment, it might interfere with itself and give you data that may have some coherence with the surface it was being reflected off of. Unless the values you are talking about are only from the model.
Depending on the strength, I'm sure a laser could punch right through something. With today's technology, most industrial strength lasers would most likely set their target on fire if they're some distance away.
