Shouldn’t we be looking for life on planets that formed over 10 billion years ago as they’ve had more time for life to form?

Planets that formed over 10 billion years ago are about 5 billion light years from us, meaning that if we could somehow study planets that far away (we can’t) the light reaching us from there would have taken 5 billion years to reach us. Therefore, we’d be seeing what the planet looked like 5 billion... Continue Reading →

How can we believe in God, but not in alien/extraterrestrial life or vice versa? This seems like a paradox to me.

I don’t see either as being dependent on the other. In other words, you can believe in God and not in extraterrestrial life. Many religious people do in fact hold that view. On the other hand, you can believe in extraterrestrial life and not believe in God. I know many people who hold that view.... Continue Reading →

Assuming that there were humans on Mars, how long would it take for a voice transmission from Earth to reach them? Would the times be different for other electronic forms of communication?

Transmissions from Mars to Earth and visa versa happen at the speed of light. However, Mars is sometimes near Earth and sometimes on the other side of the sun. Therefore, depending on where Mars is in relation to Earth in our orbit around the sun, transmission times change from 4 minutes to 24 minutes. If... Continue Reading →

If an astronomer on a planet in the Galaxy MACS0647-JD (13.5 billion light years away) were to point their telescope toward our Galaxy, what would they see?

When you look into a telescope at the galaxies and stars you are looking back in time, because it took time for the light of those objects to reach you. If it took 13 billion years to get you then you'd be seeing light that originated 13 billion years ago. If you could see clearly,... Continue Reading →

Why are we so obsessed with finding the smallest amount of life on another planet when we have amazing life that we take for granted here on Earth and we destroy it?

We have no proof life exists anywhere in the universe other than Earth. Given a planet with the right conditions, life can spring from matter and eventually evolve into something greater is the wet dream of science, but still an unproven theory.

How long would it take to travel to the nearest star?

Proxima Centauri, is our nearest star, about 4 light years away. A light year is the distance light travels in one year, or 9,460,730,472,581 kilometers. That's 9.46 trillion kilometers, or about 5.88 trillion miles. The fastest space ship we ever built was the Juno spacecraft, which in 2016 broke all speed records in space with a...
