Gel electrophoresis

Explanation:

What sort of information do you think should be sent to alien civilizations?

Answers

We could send aliens information that is good about us not the bad things. Don't share weaknesses, because that could probably lead to some bad things. We should share valuable info with the aliens.

Answer:

Information about how much we know.

Explanation:

If alien life ever gets a chance to communicate with us and we have a chance to communicate with them then we must show them how much knowledge we hold so they can better understand our customs and what to show us. We will probably show them the key sciences such as Math, Science, Biology, Phycology, Astrology, Astronomy, and our knowledge of technology. We will first show them simple problems we know like 2+4 and 1+1. After we will show them huge amounts of our psychological capabilities like our vast arrays of calculations and formulas. This is just a small fraction of our knowledge we will show them.
