If the sun was 1% further than the total distance from us what would the temperature would be on Earth?

No change. Here in the northern hemisphere, the sun is closest during our winter and further away during our summer because of the elliptical nature of our orbit around the sun. It’s not the closeness to the sun that causes summer or winter, but the tilt of the earth. That tilt causes summer days to... Continue Reading →

What are the chances that the existence of intelligent alien life is acknowledged within the next decade?

A decade is only 10 years. It is highly unlikely that even microbial life of extraterrestrial origin will be identified by 2028. Our best chance of finding life comes from two realms. Within our own solar system on the moons of Jupiter and Saturn, and from space from the SETI program (Search for extraterrestrial intelligence),... Continue Reading →

Why would we believe that if there is life on other planets that it would evolve to something intelligent?

What is intelligent life? When we speak of “intelligent life” we need to define what that entails. For example, bacterial life is not intelligent. But what about a dog? Suppose we found a dog like creature on a planet. It can respond, be happy, be angry, even be loyal. A dog is certainly not a... Continue Reading →

What’s the difference between an alien, a martian, and an extraterrestrial?

Aliens have a dual definition: the people Trump wants out of the USA and the people from outer space. Since people from outer space are called aliens, then it matters not whether they are from Mars or somewhere else. They are aliens. Therefore, "alien", "Martian" and "extraterrestrial" are synonymous, except not all aliens come from... Continue Reading →

How “Goldilocks” is our orbit? Wouldn’t we still be fine if we were as far away from the Sun as Mars is?

Curiously, in the northern hemisphere our winter is when the sun is closest to the sun and our summer is when we are farthest from the sun. Winter and summer seem more about what angle the sun is rather than how close it is. That being said, Mars has no atmosphere or magnetosphere to speak of, while... Continue Reading →

What would happen to the earth if the sun disappeared?

If you mean the sun just went “poof” and vanished forever, that would mean Everyone Dies™. The whole solar system would just fall apart. The moon would still orbit Earth, but all the planets orbiting the sun, including Earth, would be flung into deep space and become rogue planets. Without light or heat from the sun,...
