Do increased extraterrestrial ambitions threaten the future of space?

Do increased extraterrestrial ambitions threaten the future of space?

Contrary to popular belief, "Outer space is not infinite as a resource," says Meaney. "Therefore, the space industry must develop agreed upon rules to coordinate the use of space."

Meaney, principal investigator (PI) of the project and Co-PIs; Zack Donohew of SRS and Lewis Groswald, program director at Smead Aerospace Engineering Sciences; are currently working on new research to determine how to accomplish that.

The team received one of CU Boulder's 2020 Research & Innovation Seed Grants to support the work. Their submission was accepted under the Grand Challenge: Our Space. Our Future. category. The Grand Challenge is a strategic initiative dedicated to spanning and connecting disciplines across campus.

How animals sense Earth's magnetic field

There are three basic theories for how magnetoreception works, and they might all be accurate, depending on the animal. The first involves magnetic minerals. Bacteria and phytoplankton generate biological magnetite crystals that allow them to sense Earth's magnetic field. Researchers also believe that birds have them in their beaks.

The second theory, electromagnetic induction , involves animals sensitive to electric charges, such as aquatic animals, that have an internal cellular or neural mechanism that converts electro-receptivity into magnetic sensitivity .

We Should Message Extraterrestrial Civilizations, Not Just Listen for Them - Scientific American

For one thing, most of them, like most intelligent species on our own planet, are probably not technological. Then, too, the span during which a high technology species both can and might wish to make contact with a relatively low-technology species such as our own may be limited. Technological species may even regularly destroy their capacity for interstellar contact, something that not inconceivably could be our own fate.

How relatively easy it is to study child development, with billions of children growing up all the time, each with a brief and comparable trajectory. How hard it is to study the development of a high-technology species, with an n of 1 so far and a developmental trajectory of tens of thousands of years.
