Do you know what's in the ocean or even if there are secret creatures in the Amazon well no one does that's why we shouldn't spend valuable resources on space exploration? Because if you are in space for too long it can cause brain damage, it can also cause extreme chronic boredom and there are many things on earth that have not been explored.

You can get seriously injured from being in space for too long this is how.....

Staying in space for a long time can cause brain damage, according to a new study.

Being in space has well-documented negative effects on the body. But the effect of being in space on the brain has been studied less. A recent study examined five Russian cosmonauts aboard the International Space Station for about five and a half months. The researchers found elevated levels of proteins in the blood that serve as biomarkers of brain damage.

The study, which was detailed Oct.11 in JAMA Neurology, was small, and the effects on the cosmonauts' brains did not seem to be major. Still, the research could lead to further examination of the effect of being in space on the brain, especially as people begin to spend even longer amounts of time in space.

"It's not like major traumatic brain injury or anything like that," Henrik Zetterberg, a neurochemist at the University of Gothenburg in Sweden and one the study's authors, told Space.com, adding that the damage was comparable to suffering a concussion. "But still, all of the cosmonauts have this pattern of biomarker change."

The researchers took blood samples from five male Russian cosmonauts 20 days before they left for the ISS to establish a baseline, then collected additional samples one day, one week and three weeks after they returned. They analyzed the blood for five different biomarkers associated with brain damage on Earth. The researchers looked at two types of amyloid-beta proteins, which build up and form clumps in the brains of people with Alzheimer's disease.

"It's a sticky protein," said Zetterberg. "It is important to get rid of it from the brain tissue. In young and healthy people, it is rapidly cleared from the brain."

Tau protein, another type of protein the researchers looked at, can also accumulate in neurodegenerative diseases like Alzheimer's and form tangles. The researchers also measured neurofilament light chain (NfL), a protein that increases when parts of the brain called axons are injured, and glial fibrillary acidic protein (GFAP), which helps form brain cells called astrocytes. These star-shaped cells are involved in clearing out waste and protecting the brain from harmful substances. An increase in GFAP essentially means that the cell is working harder to clear out waste.

The researchers found that NfL, GFAP and one type of amyloid protein were also significantly higher after the cosmonauts returned from space than before they left. The other type of amyloid was also elevated, but only slightly. The levels of these proteins increased one day and one week after the flight but started to decrease by three weeks post-flight, though they did not go down to preflight levels.

On the other hand, the total level of tau protein initially increased slightly, then decreased to below the initial level. Zetterberg says that this could be because tau protein is typically cleared more rapidly from cells, or it could be related to the test used to measure tau, which he says isn't as good as it is for some of the other biomarkers.

Though the study did not determine what caused the increase in these proteins, the researchers think it could have something to do with the effect of microgravity on the brain's waste elimination system.

"It looks like this system might have been dysfunctional," he said. "When you get back on Earth, then it starts to work again, and then all these proteins come out in the bloodstream and are degraded."

This could be related to abnormal impacts that microgravity has on fluid in the brain, Zetterberg said, which previous research looking at the brains and eyes of astronauts and cosmonauts has observed. The researchers also think that some of their results could reflect a brain injury as the result of these effects.

Though the study examined those who had been in space for a long period of time, Zetterberg said that it's likely a shorter stay in space would also impact the brain. The research is likely to be particularly important as humans begin to spend more time in space. For instance, landing on Mars, which NASA has said it intends to do as early as the 2030s, would require humans to spend almost two years in space.

"That's a very long time," wrote Zetterberg in an email. Most of us, he wrote, "need to make sure we can stay on Earth."

The Impact of Isolation on the Neuroanatomy and Neurobiology of the Brain

We shouldn't be spending money on space because we could be exploring space just we know more about space than the ocean. Also, there are many things that we could be doing on earth as we could be solving hunger problems we could give the homeless homes. I say this because we spend billions maybe even trillions of dollars on space exploration. And we could be solving world problems with those billions of dollars or exploring more of the ocean. Also, there is so much debris in space from rockets it could be a hazard because some of those debris could fall to earth and kill a lot of people.

Why should we explore space? Why should money, time and effort be spent researching something with apparently so few benefits? Why should resources be spent on space rather than on conditions and people on Earth?

Perhaps the best answer lies in our history. What made our ancestors move from the trees onto the plains? Did a wider distribution of our species offer a better chance of survival?

Nearly all successful civilisations have been willing to explore. In exploring, the dangers of surrounding areas may be identified and prepared for. Without knowledge, these dangers have the ability to harm us. With knowledge, their effects or consequences may be lessened.

While many resources are spent on what seems a small return, the exploration of space allows new resources to be created. Resources translate into success at survival. Resources may be more than physical assets.

Knowledge or techniques acquired in exploring or preparing to explore always filter from the developers to the general population.

Techniques may be medical applications, such as new drugs or ways of living to increase the quantity or the quality of time lived. Techniques may be social, allowing the people in a society to better understand those within or outside that culture.

ESA's space programme is a strategic asset. ESA does what individual European nations cannot do on their own.

Scientists from European nations can function at world-class level in their specialist fields, in co-operation rather than competition.

By studying alien worlds, such as Venus, Mars or Saturn's moon Titan, we can place our own world in context. ESA's exploration of the Solar System is focused on understanding the Earth's relationship with the other planets, essential stepping stones for exploring the wider Universe.

While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds dangers. The chance of a large asteroid or comet hitting the Earth is small. But given time, it will happen.

Some explanations for extinctions and evolution include strikes by asteroids or comets. Our technology is reaching the point where we can detect such a threat and might be able to do something about it.

The dangers exist and knowledge can allow us as a species to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.

Earth is the only planet known to sustain life, but our ability to adapt could eventually allow us to inhabit other planets and moons.

Our lifestyles would be different, but human life and cultures have adapted in the past and surely could in the future. Space allows us to expand and succeed.

That is why I believe that we should not spend valuable resources on space. Because we could be spending them on more important things like solving world problems. Exploring the ocean. Also exploring space can hurt the human body.
