Hypothetically possible, however very unlikely.
Read the book, The Physics of Startrek. It's a bit dated (more than a decade old) but it is relevant to the topic at hand.

No known life form could survive long enough to make an interstellar journey, crossing solar systems. Such a crossing would require many human lifetimes. This is just one example of an obstacle. Still we have 3 billion+ years before our sun goes red dwarf so we have time. I am betting on an external extinction though, which will likely occur many millions of years prior to that and in any event everyone alive today will be dead in a few decades so why worry too much about it.
Interesting discussion! Check this out:
Kurzweil is also an enthusiastic advocate of
using technology to achieve immortality. He advocates using nanobots to maintain the human body, but given their present non-existence he adheres instead to a strict daily routine involving ingesting "250 supplements, eight to 10 glasses of alkaline water and 10 cups of green tea" to extend his life until more effective technology is available.[30]
Futurism, as a philosophical or academic study, looks at the medium to long-term future in an attempt to predict based on current trends. Raymond Kurzweil states his belief that the future of humanity is being determined by an exponential expansion of knowledge, and that the very rate of the change of this exponential growth is driving our collective destiny irrespective of our narrow sightedness, clinging archaisms, or fear of change. Our biological evolution, according to Kurzweil, is on the verge of being superseded by our technological evolution.

Kurzweil gained a large amount of credibility as a futurist from his first book The Age of Intelligent Machines. Written from 1986 to 1989 and published in 1990, it correctly forecast the demise of the Soviet Union (1991) as new technologies such as cellular phones and fax machines critically disempowered authoritarian governments by removing state control over the flow of information. In the book Kurzweil also extrapolated preexisting trends in the improvement of computer chess software performance to predict correctly that computers would beat the best human players by 1998, and most likely in that year. In fact, the event occurred in May 1997 when chess World Champion Gary Kasparov was defeated by IBM's Deep Blue computer in a well-publicized chess tournament. Perhaps most significantly, Kurzweil foresaw the explosive growth in worldwide Internet use that began in the 1990s. At the time of the publication of The Age of Intelligent Machines, there were only 2.6 million Internet users in the world,[32] and the medium was unreliable, difficult to use, and deficient in content, making Kurzweil's realization of its future potential especially prescient given the technology's limitations at that time. He also stated that the Internet would explode not only in the number of users but in content as well, eventually granting users access "to international networks of libraries, data bases, and information services" (such as Wikipedia). Additionally, Kurzweil correctly foresaw that the preferred mode of Internet access would inevitably be through wireless systems, and he was also correct to estimate that the latter would become practical for widespread use in the early 21st century....MORE:
