As a senior engineering student, that has taken almost half of the courses in english, I can assure not only that I am proficient in this language, but also that I have the scientific and technical knowledge needed to write a science article in no matter which style of writing is needed, since I have written in technical, academic, colloquial and also fun style. In addition to that, I have a personal interest in quantum physics, astronomy and the universe in general, I have read many books and articles on this topic as a hobby, so I have a fair understanding of it.
Relating to my writing experience, I have participated as a guest writer on a launching academic blog (set up by two of my physics professors that chose me for my skills) addressed to professors seeking new methods and technologies to use at their classes. Apart from that I wrote two articles for a blog named society19, which is addressed to college students. Both articles went viral. So although this is my first project bet on this platform I have all the skills you need.
In my bet I stated that I needed 3 days to complete the article, but I can shorten that time to maybe just a day, depending on the background and the aims for the content.
