Our knowledge has increased in the past 50 years, more the entire previous 950 years.
Over the next 50 years how much will our knowledge grow? Not really clear we know how much, but it will seem what we now know, trivial.
Are we alone in the universe? Possibly, but we will not likely be able to find out, based on our existing knowledge of the laws of Physics.
We continue to "find" exoplanets that might be conducive to carbon-based life continues to grow. We base it on the following:
- An atmosphere rich in oxygen, nitrogen, and water vapor.
- The planet's temperature should allow for liquid water.
- A magnetic field is essential to protect the planet from harmful stellar radiation.
- Plate tectonics may play a role in stabilizing the climate and recycling essential chemicals.
- Neighborhood. Other planets in the neighborhood, form a "protective" zone, protecting with their gravitational "deflection", the planet from celestial bodies capable of smashing in, and destroying what life developed.
The closest exoplanet identified as potentially habitable (meeting the above conditions) is Proxima Centauri b. It Orbits Proxima Centauri, and is 4.2 light-years away from us.
If a civilization had developed on it, that's about as advanced as ours, and they could travel at half light speed, accounting for time dilation, by the time they reach us, 4.85 years would have elapsed. Not really do-able if their technology is equal with ours.
Assuming our fastest probe, the Parker Solar Probe (700,000 km/h), it would take more than 6,500 years to reach earth from Proxima Centauri b.
The faster we approach the speed of light, the bigger time dilution. If a vessel is traveling near the speed of light for 4.2 years or so, by the time you reach earth, 4.2 years would have elapsed for earthlings, but you would have only aged 1.7 months or so. If you return to your planet, by the time you arrive, you would have aged 3.5 months or so, but the people who were left behind, would have aged more than 9 years or so.
Perhaps, in 1,000 years, we would develop a better understanding, and techniques to nullify the effects of time dilation, or a better understanding of quantum entanglement, and instead of being there, we (or some aliens), would be able to instantly "observe" or "experience", regardless of distance.
But for now, this is probably why we don't have aliens running around, doing anal probes.
Just wondering how many of our beliefs and "knowledge" will have changed after another thousand years of scientific learning.

@Northwest Proxima Centauri is a red dwarf though, the type of star that just couldn't support life on any planets within its system, due to, among other things, the fact that any planet within the star's habitable zone would be far too close to the star, resulting in captured rotation (i.e. one side of the planet constantly facing it, in the way our moon always shows the same side to us).

Significant requirements for biological life on Earth ONLY.
And quite frankly the scientific theory of abiogenesis that life sprung up from none life is a very very long stretch......
The scientific theory of Panspermia makes more sense - that life came down from space.
I guess you haven't heard or ignore President Ronald Reagan saw an UFO ___ President Jimmy Carter saw an UFO ___ President Barack Obama said there's something flying around in the skies and we don't know what they are ___ heck Trump even started the space force ___.
Last year Medium Ranking military personnel testified before Congress of unidentified flying objects continually flying around their Air Bases ___ 2 to 3 years ago the Pentagon release radars where Air Force personnel were talking about unidentified flying objects - a fleet of them in one case doing maneuvers that no earthship could do. The whole hearing is on YouTube. It just don't link to this site.
[media=https://youtu.be/YnMjLD3sWQA?si=prCi-BmFbWiofA2W]
And what these objects do humans would not be able to withstand __ nor can any craft constructed by humans is capable of doing what these crafts do.
And there is much much more that could be discussed.

@Bel6EQUJ5 it's not magic. They ARE technologically more advanced. Only certain type of people would believe the earth is the only place in this universe that has life forms. Only certain type of people would ignore I witness accounts.
Please don't waste ANY MORE of your time by responding.
I won't

@Bel6EQUJ5 apparently you don't know the definition of the words extraterrestrial/alien alien ___& when you use alien as extraterrestrial both means not of this world - anything outside of Earth's atmosphere - coming from another world......... God - the Angels - the devil - even Jesus are not from Earth that makes them by the definition of the words which were coined in the past few centuries what man has coined as alien / extraterrestrial.
Fairies and Father Christmas heck I was read those stories as a child and didn't believe in them then and definitely don't believe in them now.
God and the angels on the other hand I believe in. My eyes have seen the glory of the coming of the Lord even when a child. And what my eyes have seen my heart believes.......
But you wouldn't know that - you've rejected his truth and so be it.
Now personally I don't care whether you believe or not believe that's your business....... I read a post commented on a post - you disagree with what I say fine that's your business........ conversation over on my part - I will not reply to you again .........

Let’s think logically, if there’s multiple universes, all including many galaxies, each galaxy including many solar systems, and not to mention that aliens might have different living conditions entirely, the LOGICAL answer is that aliens exist somewhere.
@Sometimesitsbetter2letsome1go It's possible I may win the lottery. Do you think it's actually going to happen though?
@Bel6EQUJ5 I believe in the multiverse, so yes, it probably has already happened in another universe, if that puts my statement into context.
@Bel6EQUJ5 yeah but it’s possible that you’ll die today, it’s inevitable that you’ll die eventually, I mean in that type of way, if it hasn’t happened it will, the universe has lasted for millions of years and will continue to do so, not to mention that there has been habitable planets found, to humans at least. Plus they don’t have to necessarily be “aliens” just a living organism on another planet.

That channel made a big L claiming we humans only became the [apex predators] of the planet only due to our intelligence. Wrong, we became superior over all other species due to our intelligence and adaptability (along with evolving to have opposable thumbs); no other species except maybe rats/mice can adapt as well as we can.
Also, absence of evidence does not equal to lack of evidence, which the channel sort of acknowledged. Let's not forget that scientists only conducted their research for nearby planets and star systems within the Milky Way. There could be advanced aliens that exist in a galaxy or even supercluster far, far away.
I'm willing to bet the Irish/Scottish guy also just read the abstract and conclusion, maybe the graphs/diagrams, without actually reading the entire journal articles. His accent is also really fucking annoying and cringe, I'm surprised I managed to watch the entire video without roasting his ass in the video comments.

@uikakarotuevegeta People can't help the accent they happen to have. There might be people who find your accent really annoying, whatever it may happen to be.

40 billion earth-like planets in our own galaxy aren't enough, huh?
@LordShadowfire No, they're not. A large universe may be a necessary requirement for life to appear, but on its own it is not sufficient.
LordShadowfire · 46-50, M
@Bel6EQUJ5 What did I just say? It's not about there just being a large universe. 40 billion planets in the Milky Way galaxy alone have the potential to support life as you and I know it. And let's be honest. That's a very narrow definition of life.

Argument from incredulity, a common mistake that people make in this debate.
Yes, he's right about the abundance of chemical elements that would have to go into the formation of any form of life that we'd recognise as such, and I'd also bet there are microbial aliens out there somewhere, but...
Advanced aliens? Nope. Are you familiar with the concept of "Great Filters"?

I don't accept that either; the belief that we're not important in the grand scheme of things, and simply because of our relative physical location (in this case, our distance from the centre of the galaxy). Location doesn't determine worth.
