Technically the solar system is a multi-body system, and everything nudges everything else, but the mass of the earth is far greater than the mass of the asteroid, to the point that it doesn’t matter.
In a certain way, it does feel close. We can’t figure out how to go faster than light, but we could theoretically get to a significant fraction of c and 20 years isn’t such a long time to plan for in terms of getting a probe there to start relaying messages that take 20 years to get back.
I mean, it’s the span of a career, but people could conceivably work on the launch and live to see it return data.
The planetary alignment is a celestial event that occurs periodically within the solar system where Gaia and the other five planet gods known as the Astra Planeta align. The event was prophesied by the Fates to occur again 18 years after Hercules’ birth and would allow Hades to conduct a “hostile takeover” against Mt. Olympus with the help of the Titans.
Energy released by the planets lining up created a vortex that moved the water away from the place in the ocean where the Titans had been imprisoned by Zeus back when the Earth was new. Hades then broke the energy gate covering their prison and the Titans climbed free to begin an assault on the home of the gods. However, in their anger, they initially headed in the wrong direction until Hades got them turned around.
Putting on my sci-fi hat; a distant galaxy that is likely a billion years older than ours, very likely has had enough time to develop life somewhere in the trillions of stars that formed within it, by the time the photons of that galaxy finally reached us and hit that very specific telescope sensor at that very specific moment the JWT engineers were observing.
Barnard b [2], as the newly discovered exoplanet is called, is twenty times closer to Barnard’s star than Mercury is to the Sun. It orbits its star in 3.15 Earth days and has a surface temperature around 125 °C. “Barnard b is one of the lowest-mass exoplanets known and one of the few known with a mass less than that of Earth. But the planet is too close to the host star, closer than the habitable zone,” explains González Hernández. “Even if the star is about 2500 degrees cooler than our Sun, it is too hot there to maintain liquid water on the surface.”
Mathematically, it’s possible, but scientists are still skeptical about whether or not they are real. They’re called white holes and you can actually create a model of one in your kitchen sink. If you let the water just hit the bottom and spread out evenly in all directions, you can kind of visualize the way it’s supposed to work. Action Lab on YouTube actually has a pretty good video about it which I suggest watching if you’re interested. youtu.be/p3P4iKb24Ng?si=b3_RHuj0J3F_7DC1
Tangent, but you don’t need to include the question mark or anything after in most urls. Definitely not YouTube links. It’s just YouTube telling itself who shared the info (you) and they use that to track shit. But the link works just as well without it, and you’re not voluntary spying on yourself.
I have not heard a car for a few hours. Not even the rumble of traffic in the distance and I can see the night sky without light pollution. It is a very privileged experience in some ways and while it has its advantages we are measurably disadvantaged in most human development metrics: health, education, income etc compared to people living in urban areas of our own country. The disadvantage is real and pops up everywhere from cancer survivability to suicide rates. Equitable internet access is more important than many people appreciate. If we can improve services to everyone AND protect radio astronomy that is a worthy goal.
How does fiber being cheap help them if no ISP is willing to dig miles and miles of trenches to lay it and connect to their home? I live in the middle of suburbia and don’t have access to fiber.
Your comment about subsidizing their lifestyle doesn’t really make sense. What are you subsidizing exactly? This tech is also useful in poorer countries that don’t have the infrastructure at all.
Any chance the Starlink satellites could be built to double as a sort of large-array telescope themselves, to compensate for the ground-based interference?
What’s more likely to happen is Starship’s will be launched where the entire ship becomes the telescope, and then we’ll have arrays of these much further away.
Not sure if it’s the same for radio, but for optical that means we can get a 9 meter mirror up there without any expensive folding mechanism, and who knows how big if we fold them as the fairing is not only wider but also longer.
Cost would go from billions to hundreds of millions or less. James Webb cost 10b.
The James Webb folding mirror is 6.5m and was folded into a 4.5m fairing…
From my brief look into the topic, interferometry tech is not quite there yet, but might be in the next few decades. Interferometry is more difficult with shorter wavelengths.
