00:00If you ever look up at the night sky on a clear night, far away from city pollution,

00:05one thing becomes obvious.

00:07The universe is vast, unimaginably vast.

00:10We see thousands, even millions of stars shining above us.

00:14So, the question arises, just how big is our solar system?

00:20It takes sunlight only 8 minutes and 25 seconds to reach Earth from the sun.

00:25But to reach the far edge of our solar system, that same light takes around 545 days.

00:31That means even a beam of light takes nearly a year and a half to travel across the solar system.

00:37Can you believe it?

00:38The diameter of our solar system is about 100,000 times the distance between the sun and Earth.

00:45For example, Jupiter is so massive that you could fit 11 Earths across its diameter.

00:50But it's not just the size, it's the distance that's truly mind-blowing.

00:54If someone were to travel at an average speed, it would take them around 570 years to reach Neptune.

01:01And this shows just how small we are in this vast cosmos.

01:04A spacecraft named Voyager 2 was launched back in 1977.

01:09In 2018, NASA announced that it had crossed the boundary of our solar system and entered interstellar space.

01:15It's twin, Voyager 1, is currently the farthest human-made object, located nearly 22.2 billion kilometers away.

01:24And still, it hasn't completely escaped the sun's influence.

01:27So, what does it all mean?

01:29Even with modern technology, it's impossible for a single generation to cross this solar system.

01:35Some scientists say that in order to fully break free from the sun's influence,

01:40we may have to travel halfway to Proxima Centauri.

01:44This is our closest star, whose light takes 4.24 years to reach us.

01:49From this, we can understand that the sun's influence extends 2.12 light-years away.

01:55That's nearly 13 trillion miles.

01:58It's simply unbelievable.

01:59In the face of such vastness, we humans are really so small, aren't we?

02:05To travel from one end of the solar system to the other with our current technology would take about 30,000 years.

02:12Can you imagine?

02:13A journey of that length, most of which would likely be lonely, silent, and lifeless.

02:19But there is hope.

02:20We're on the verge of Mars exploration.

02:23In the next decade, we may see the first black woman and man land on the moon,

02:27and the first human footprint on Mars.

02:30That will mark the beginning of a new era for humanity.

02:33And what if we used the fastest spacecraft like the Parker Solar Probe?

02:38If that speed were directed toward Mars, it would take only 16 days.

02:43But the planets aren't stationary.

02:45They're constantly orbiting.

02:47And paths in space aren't always straight.

02:50They often bend due to gravity.

02:52So, in reality, any journey depends on where the planets are at that specific time.

02:58Now, scientists are looking toward a future technology called photon propulsion.

03:03If this technology is realized, one day, we might be able to travel through space at one-third the speed of light.

03:10That's our power, after all.

03:12We don't know what stopping means.

03:14We don't know what limits are.

03:15At present, with current technology, it would take us 30,000 years to exit our solar system.

03:22But in the future, technology might change everything.

03:25For instance, a new concept called photon propulsion uses light itself to push a spacecraft forward.

03:32If this technology becomes practical, we might one day achieve one-third the speed of light.

03:37That's all for today.

03:39Just thinking about how vast our solar system is can make your head spin.

03:43But within that vastness lies humanity's endless curiosity, the desire to explore, and the boundless potential of technology.

03:52If you enjoyed this, be sure to share it.

03:55And I'll see you in the next video.
