The fact that we are feeling online, in our mobile phones, is interfering with the work of astronomers-they want to detect black holes and know exactly where we are in the universe, but we are always blocking your vision.
Scientists who accurately measure the position of the earth are in trouble. Its measurements are essential for the satellites we use every day for earth’s navigation, communication and observation.
The realization of these measurements – using the science of geodesia – depends on the location of black holes in distant galaxies.
The problem is that scientists need to use specific frequency ranges on the highlighted radio spectrum to locate these black holes.
And with the increased wifi, mobile phones and satellite internettraveling in this highway begins to look like a traffic jam that is making irritated The scientists.
It is urgent to see the black holes
Os satellites and the services they provide became essential to modern life. From accuracy navigation in our pockets to the measurement of climate change, through the management of global supply chains and making power networks and banking services possible, Our civilization cannot work without your companions in orbit.
To use the satellites, we have to know exactly where they are at a given moment. The exact positioning of satellites depends on the so -called “Global geodesy supply chain”.
This supply chain begins by establishing a reliable framework as a basis for all other measurements. Since satellites are constantly moving around the earth, the earth is constantly moving around the sun and the sun is constantly moving through the galaxy, it reference frame must be carefully calibrated through some relatively fixed external objects.
It turns out that the best anchor points for the system are the black holes in the heart of distant galaxies, which expel radiation flows as they devour stars and gas.
These black holes are the most distant and stable objects we know. Using a technique called interferometria Very long base line, we can use a network of radiotlescopes to fix the signs of black holes and separate the rotation and oscillation of the earth from the satellite movement space.
Different roads on the Radio
We use radiotlescopes because we want to detect radio waves from black holes. Radio waves cross the atmosphere smoothly and we can receive them by day and night and in all weather conditions.
Radio waves are also used for communication on Earth – including things like WiFi and mobile phones. The use of different radio frequencies – different tracks on the highway of the radio – is closely regulated and some narrow bands are reserved for radioastronomy.
However, rather, the highway of the radio had relatively little traffic. Scientists often deviated from the radio astronomy ranges to receive the signs of black holes.
To achieve the very high accuracy necessary for modern technology, geodesia currently depends on more than just the tracks reserved exclusively for astronomy.
Radioelectric traffic is increasing
In recent years, the Electromagnetic pollution provoked by man increased considerably. When Wi-Fi and mobile phones arose, scientists reacted changing to higher frequencies.
However, Frequency ranges are exhausted. Six generations of mobile telephone services (each occupying a new track) are occupying the spectrum, not to mention the internet calls sent directly by a fleet of thousands of satellites.
Currently, the multiplicity of signs is often too strong for geodetic observatories to be able to see through them the very weak signs emitted by black holes. This endangers many satellite services.
What can you do?
To continue working in the future – To maintain the services we all depend on – Geodesia needs a few more tracks on the highway of the radio. When the spectrum is divided through international treaties at world radio conferences, Geodesists need a place at the table.
Other potential solutions may include Radioelectric silence zones around our essential radiotlescopes.
Works with satellite suppliers are also underway for Avoid pointing radio emissions directly to the radiotelescopes.
Any solution has to be global. But the radio frequency spectrum is regulated mainly by each nation individually, which makes this a huge challenge.
Perhaps the first step is to increase awareness.
If we want satellite navigation to work, our supermarkets are fueled and our money transfers in line will be safe, we have to Ensure that we have a clear view of black holes in distant galaxies. This means cleaning the highway of the radio.
