The modern science speculates the possibility of human civilisation to spread beyond the Earth. And it is becoming a necessity in which we are not sure about whether the climatic conditions or some kinds of catastrophes force humans to abandon the Earth. The experts conduct study on how humanity may gradually develop a civilisation outer space. It is super excited for many to experience the science fictional stories in real. The impressive developments in robotics, biotechnology, and nanotechnology could enable us to construct habitable cities on Mars. Leading scientists predict the human future in many ways. Here are a few questions that need to be answered.
1. Is there any human life possible beyond Earth?
Famous British cosmologist and astrophysicist Martin Rees says that mass emigration from Earth to another planet is dangerous. Next century, people may start migrating to Mars and a post-human era will start gradually.
2. Which planet is likely suitable for human extraterrestrial life?
Carol E. Cleland, a philosophy professor from University of Colorado says that the life in Mars is possible in the coming 20 years if we have abundant microbial life there. He also added that the life in Titan will be different from Earth. Titan is very rich in organic molecules but very cold and no liquid water.
3. Will everyone on the Earth get sufficient health care in near future ?
Raj Panjabi, who is an instructor of Harvard Medical School answers that people who stay in remote place are still not aware of the proper health care. As per WHO, one billion people in their entire life time do not meet a health worker. In order to over come this crisis, health care departments in each country must deploy more health workers across the globe.
4. What is brain science? Will this change the criminal law?
Brain Science is a branch of study about the architecture of brains and how neuron works in each individual. Patricia Churchland, the professor of neuroscience from University of California, San Diego explains all the mammals and birds have the capacity for self-control especially while behaving in a social context. So it is impossible to change the criminal law based on people’s brain.
5. Will Homo sapiens survive another 500 years?
Carlton Caves, Professor in physics and astronomy from University of New Mexico says that the survival of Homo sapiens is possible since all the odds are good for it. No catastrophe will wipe out the life entirely.
6. Could we replace all the tissues in the human body one-day?
Robert Langer, David H. Koch Institute Professor from the Massachusetts Institute of Technology explained that in the coming centuries, it would be possible to replace all the tissues in our body by plastic tissues. The tissue in brain is quite complicated to understand and it may take an enormous time of research.
7. Will the human being be able to understand the nature of consciousness?
Consciousness mean the awareness of a particular person’s memories, unique thoughts, sensations, feelings, and environments. It means consciousness is the self-awareness and about the world around you. Christof Koch, president for from the Allen Institute Brain Science says it is really impossible to understand the true nature of consciousness.
8. How closer we are in preventing nuclear holocaust?
Even though many countries are equipped with nuclear weapons, they are now trying to remove them from main locations. Since the attack of 9/11 in U.S, they are trying to focus on reducing the danger of nuclear explosions. Each country is aware of the aftermath of nuclear war.
9. Is it possible to avoid sixth extinction?
Edward O. Wilson, the research Professor at Harvard University explains that the sixth extinction can be paused if we take quick action. The loss of habitat is the main reason of an extinction, he added.
10. How can we find out food without destroying our planet?
Pamela Ronald, the professor at the University of California says we must reduce crop waste, consumer waste and reduce the consumption of meat. Integration of proper seed technology and its management is another way to save our planet. We must understand the difficulties the farmers face.
11. Is colonizing outer space possible?
Catharine A. Conley from NASA says colonize means the way we interpret. If it means landing of robots, we had already done that. If sending microbes from Earth, that also tested on a long run. Human life to an extent is possible there in Mars. But reproduction is not possible. And the life will not be similar to the Earth.
12. Will we discover another Earth?
Scientists have researched the diversity of many other planets. They also found the crucial element in existence of human life is water- where many planets have the traces. And they assume that other planets may also have the necessary ingredients for species, all that we need to find out.
13. Will there be a permanent cure for Alzheimer’s?
Reisa Sperling, professor of neurology from Harvard Medical School confessed that the complete cure cannot be promised now. May be in the coming decade, delaying the symptoms can be possible. All the prevention trials have been started already.
14. What is dark matter all about?
Like normal matter, the dark matter is not interactive with the electromagnetic force. Hence the scientists say it is really difficult to spot it. But they are hopeful in more findings by conducting researches and experiments.
15. Will we ever able to control some of the serious brain conditions like schizophrenia or autism?
The modern medicine has not found a permanent cure to fix this. Multiple disputes have been raised based on different opinions. Our medical science is still conducting studies to find out an early detection for these diseases.
16. How can wearable technologies detect our emotions?
Neuroscience explains all decisions made by the individual are initially based out of emotions, even-though they justify them with logic or reasons. Suppressing emotions can cause brain to under performance. The scientists promise the emotion engineering technology can offer a major contribution to the human emotions and can stimulate the brain by wearing them in your body.
17. When will we able to stop animal testing in drug development?
The advance studies in biotechnology suggest we are able to create artificial human organs and mimic the psychology. If these techniques are better in providing the drug testing efficiency, experiments on animals can be stopped.
18. Will sex become less important?
Henry Greely, from Stanford University says sex for the purpose of reproduction will become least common. In the coming future, the science will be able to derive eggs and sperm from the stem cells. This can help in predetermination for genetic diagnosis on embryos widely.
19. Will gender equality be accomplished in science?
Gender equality in science is possible only if we act now, not just sit back wait for it to happen. We must hire more women in science and technology fields. We need to bring-out more family friendly policies.
20. Will the modern technologies help in detecting earthquakes and natural calamities days in advance?
All the natural calamities can be predicted earlier except earthquakes. We will not be able to predict the earthquakes days in advance, but can provide seconds-to-minute warning which will help people to move to a safe location.
