Final answer:
The question of whether human travel beyond our solar system is possible involves the science fields of astronomy and physics. While it is not currently feasible, ongoing research in space travel and technology keeps it as a topic of scientific exploration. Therefore correct option is A
Step-by-step explanation:
The question 'Is human travel beyond our solar system possible?' can be answered using science, specifically the field of astronomy and physics. The conceptual and practical feasibility of interstellar travel incorporates multiple scientific disciplines, including engineering and chemistry, to understand the challenges and develop potential technologies for such journey. While current technology does not allow for practical human travel beyond the solar system, advancements in propulsion systems, life support, and other space travel technologies are continuously researched. Scientifically, it's agreed that interstellar travel requires overcoming immense distances and would need significant technological progression.
Astronomy is at the forefront of exploring such questions, and with continuing research in space physics, the dream of human travel to distant stars remains a subject of scientific inquiry. Future developments in technology and our understanding of the universe could make this idea more plausible.
