What about radiation? I understand that with a red dwarf the goldilocks zone is going to be much closer since it doesn’t produce nearly the heat of the sun. But....how about radiation from the Red Dwarf? Would a planet close enough to be in its goldilocks zone be bathed in so much radiation that life would be impossible there?
Life is only possible on earth and we only have an atmosphere because our molten nickel-iron core forms a magnetic shield against solar radiation. I would assume that for life to be possible, this planet must also have a magnetic shield.
It is unclear if there is intelligent life in the universe...
Yes, it is. It certainly is.
The Voyager space probes are the fastest vehicle launched by man yet and they left our solar system a couple of years ago.
I thought that I read at the time they were moving at 17000+ miles per hour.
Its very questionable if they could even reach out that far without striking a meteor or something else.
We topped 200,000 mph before Voyager was even launched. We’re going to go 450,000 mph next year. With ion propulsion technology, we could probably go several million mph within a few years if we tried. Of course, light speed is something like 670 million mph
(Unless someone discovers a kind of quantum skip)
Now, using computer models similar to those used to study climate change on Earth, researchers have found that, under a wide range of conditions, Proxima Centauri b can sustain enormous areas of liquid water on its surface, potentially raising its prospects for harboring living organisms.
Aren’t they the same computer models that said that there are 3000 dead Puerto Rican’s from last years hurricane? Liberal first on the space ship!
#9 that happened in some science fiction story I read.
In the last 100 years we have gone from horse and buggy to cell phones in the generations that in will take the craft to get there FTL or something similar may well happen.
It would probably be more cost effective to create a megastructure in our solar system than to migrate any number of people to a distant inhospitable planet. Robots could build a living space to house thousands and it could orbit the earth or sun and be easy to get to.
