The truth is that interstellar travel and exploration is technically possible. There's no law of physics that outright forbids it. But that doesn't necessarily make it easy, and it certainly doesn

https://en.wikipedia.org/wiki/Interstellar_travel
Interstellar travel is the hypothetical travel of spacecraft from one star system, solitary star, or planetary system to another. Interstellar travel is expected to prove much more difficult than interplanetary spaceflight due to the vast difference in the scale of the involved distances. Whereas the distance between any two planets in the Solar System is less than 55 astronomical units (AU

The author of a new research article in the International Journal of Astrobiology says that ETCs may not need starships to escape existential threats and travel to another star system. They could instead use free-floating planets, also known as rogue planets. The article is "Migrating extraterrestrial civilizations and interstellar colonization

Needing someone else to be there beforehand is not feasible for the first interstellar flight. Worse, the physical effects of traveling through a permanent or semi-permanent wormhole would warp and destroy any matter. You would arrive at your destination as a plasma. 9.

Problems with interstellar travel: Current technologies. Interstellar distances are of course immense, but it can be difficult to fathom quite how immense. Travelling to our closest other star, Proxima Centauri, would be equivalent to travelling to and back from Pluto at its furthest distance from us in its orbit 2667 times.

Interstellar journey: The aim of the Starshot project is to send a tiny spacecraft propelled by an enormous rectangular photon sail to the Alpha Centauri star system, where it would fly past the Earth-like planet Proxima Centauri b. The four red beams emitted from the corners of the sail depict laser pulses for communication with the Earth.

Proxima Centauri b seems to be the closest exoplanet in its habitable zone. At a distance of $4.2$ lightyears, travel to this planet within a human lifetime is not impossible prima facie, however doing so requires a mean velocity that is an appreciable fraction of the speed of light, i.e. around $0.1 c \approx 3 \times 10^4 \text{km/s}$.. My questions concern the problem to travelling at this

It's at least theoretically possible, unless the interstellar medium has a lot more particles and dust than we think. It's really just a question of whether or not the energy cost of traveling at 0.1-0.2c is practical. If it isn't, generational ships or automated ships with seed banks should still be doable.

A much easier solution is to develop the tech to copy the human brain to a machine, especially since that will be useful for many more than than just space travel, but will also eliminate the hostile environment problem and kind of allow for traveling at the speed of light in the form of electromagnetic data vs big old life support spaceship
