UFOs are real.
Alien spacecraft on earth are not.
The distances between stars make interstellar travel a pipe dream.

It reminded me of Interstellar.

Have you by chance read Ender's Game? It's been a while for me, but I believe those books used this technique for interstellar communication, think it was called the Ansible.

Perhaps (interstellar steam rockets excluded), but it is often effectively removed from use.
The natural replenishment rate is well below our use rate. That's why central California is sinking, we pulled so much water from the ground that it's collapsing beneath the farm belt, while also taking so much river water the fish can't survive.

Using it usually means contaminating or evaporating it. The latter will be recouped eventually by simple condensation, but the former is often a difficult process to reverse and often can be permanent.

This achievement has earned you your "Golden One" Level 77 Badge!

Uh, what? Nobody said that at all. It is neither a "classic example" nor an assumption. The trajectory has been tracked since it was discovered, which is hyperbolic around the sun, and the speed of the object is such that there is no way it could have accelerated to its current velocity due to the gravity of our sun alone, hence it has to be interstellar, picking up kinetic energy from another system outside of our own. The orbit is not improbable, it is unusual compared to trajectories of asteroids that exist within our own solar system. Sharpen your crayon there bud, and stop trying to impress people with your new thesaurus for hipsters (come on, "undergird"?? Really?)

They said they believe it is interstellar because of its improbable orbit. This is a classic example of the assumptions that undergird much of modern cosmology

Thought Cafe - Is Interstellar Travel Possible? has been added as a related post - related requested by ChaosEngine on that post.

That got pretty deep *quality

Kinda like Interstellar but BETTER!

As he mentioned the problems are numerous and extremely difficult to solve. One of the problems he didn't mention was navigation. Stars are so far way that if the trajectory of the probe is off by even by a fraction of a fraction at the start of its journey it could miss its target by light years. Don't even get me started on interstellar radiation and the shielding technology we don't have.

Your video, Going Interstellar - Photonic Propulsion, has made it into the Top 15 New Videos listing. Congratulations on your achievement. For your contribution you have been awarded 1 Power Point.

I'm confused. They imply a 3 day trip to mars is possible, but is that at the maximum speed photonic propulsion can deliver, or do they include the acceleration and deceleration times? As I understood it, photonic propulsion can deliver extreme speeds, but only at a minimal acceleration. That means that maximum speed is much faster, but accelerating to that speed takes immensely longer, and the same goes for deceleration. Maybe they've invented a new method I've not heard of with much higher acceleration, but that's not really mentioned in the video.
They actually seem to imply they plan to use the same tech as cyclotrons, which means essentially a huge rail gun (and that's not photonic propulsion BTW, it's magnetic). Again, the amount of propulsion is miniscule, but the top speed is high with that method. Yes, you can expel matter at near speed of light, but only in tiny amounts and using huge amounts of energy.
Yes, it may take 10 minutes to achieve 30% the speed of light....with single molecules or atoms.
There are MANY reasons why we can't do this at macro sizes. Just look at the size of a cyclotron needed to accelerate an atom to those relativistic speeds. Now think about sizing that up to accelerate enough matter to move a spaceship instead of a single atom and it's likely near the size of the entire planet. We won't be building a cyclotron that size ever, nor will we likely ever shrink the accelerators to a size where they can fit inside a spaceship to shoot trillions of atoms out like a light speed gun. They are just too big and use too much power. Maybe once fusion is perfected and miniaturization also perfected it could work for interstellar travel, but never for local space travel, the acceleration levels are just too small.
Also, it seems solar sails give the same or better acceleration to the same top speeds without the impossible technology....but they don't work too well for stopping except at other stars.

Very other-worldly, dude.

Reminds me of Interstellar.

We are a known quantity on many interstellar maps if the evolutionary paradigm is true. It wouldn't take that long for a sufficiently advanced civilization to locate every planet that has life on it, especially if they could use inter-dimensional travel. They could automate everything using robotics, or by some other means unknown to us. Perhaps they could even instantly colonize those planets using sentient robots.

The point is that we are a resource to be exploited and after an estimated 15 billion years of the Universe existing, according to the secular narrative, there should be many civilizations out there capable of doing just that. That we haven't been contacted or seen any activity at all is more than curious; it is dramatic evidence that we are in fact alone in the cosmos.
