Do you guys ever...

Just watch the Nasa feed?

This is fainting to me that right after you see this mysterious floating object? The feed is cut.

I'm not a big conspiracy theorist, but often times I watch and nothing can be spotted and the feed isn't cut, but when something unidentifiable comes into view the feed ends shortly after and often stays down for an hour or so.

Hummmmm....any thoughts? To be honest, I'm not sure if I believe Aliens or Extraterrestrials to exist or not.

You have to put things into perspective.

The nearest star system to the solar system is called Alpha Centauri. It's 4 light years away. That means if you were to travel to Alpha Centauri from Earth at the cosmic speed limit of 670,000,000 mph or 300,000,000 m/s, it would take you 4 years (in the reference frame of the earth). At a more realistic speed, say about 250,000 mph, it would take 600,000 years.

So, why not just travel close to the speed of light? There are numerous complications with that. The simplest is impacting small particles in the interstellar medium. A more complex argument would involve calculating the energy and time required to accelerate close to the speed of light and then decelerate. The energy required to accelerate a car in space close to the speed of light is on the order of magnitude of 10^20 Joules, neglecting the weight of the fuel required. You would need a lot of fuel, a lot of energy and you won't be traveling close to the speed of light across the entire distance.

Furthermore, Alpha Centauri is a triple star system. It consists of three stars orbiting each other, and there is no hope of finding life there.

Additionally, traveling to objects just 4 light years away is not feasible. Even if you were to somehow arrive at the star, it would take 4 years to send a message back to Earth, and another 4 years for you to receive a response. If you were to travel to a star just 10 light years away (still among the closest stars to our own), the communication delay would be 20 years. There is no effective way of communicating across that vast of a distance.

One can argue that, even if alien beings did exist, it is not possible for them to travel to Earth. Even if you could travel at the speed of light, you may still have to travel hundreds or thousands of light years before finding a habitable planet, and if you could survive the mission, how are you going to inform the folks back home? For this reason, many scientists do not believe aliens are visiting Earth.

If they are, it would have to be by some extraordinary means. Not by "nuts-and-bolts spacecrafts," as the famous alien astronaut theorist and scam artist has claimed.

I can add that it is possible for a person to travel to the nearest galaxy, Andromeda, if he or she can approach the speed of light and utilize time dilation as described in the theory of special relativity. However, once he or she arrives at Andromeda, several millions years will have past on Earth, and he or she will have little chance of returning. So, it would be a suicide mission, but it is, at least, possible. Special relativity explains why particles with mass can not travel at the speed of or faster than light, and why information cannot travel faster than light.

there have been many UFO reports of unidentified ships.

so this blows a hole in your comments about aliens not visiting earth.

[yitzchak]

How?

I can easily say I saw an alien spacecraft, big foot, a leprechaun and a ghost. Do you think that implies that I actually saw any of those things, or that they exist?

The majority of big foot sightings are most likely people seeing bears walk on two legs. The majority of UFO sightings are probably due to similar ignorance.

Nevertheless, what I said is based off of physical measurements and laws, with just a few fair assumptions, like there probably isn't any intelligent life on Alpha Centauri or other nearby stars.

[dilbert firestorm]

I hate to break this to you. those UFO sightings are not borne out of ignorance.

I have seen a UFO. was I hallucinating? not bloody likely, nor was I ignorant.

Alcohol makes women prettier, and UFO'S more common.

Ever noticed how as our technology advances UFO'S become more advanced?

[yitzchak]

If you really saw a UFO, then let's hear more about it. What did you see?

disagree with that view UFOs being more advanced.

they really have not changed that much if at all.

Yea, it's kind of what this thread is about. There's no point in saying you saw a UFO without giving any details.

[Mr MojoRisin]

What if that object in the feed isn't a UFO at all but rather a Satellite. They say there are over two thousand satellites in low earth orbit same as the ISS. That feed certainly would pick up on an orbiting satellite, right?

Ever seen pics of the ones early 1900's. They were cigar shaped.

water balloon, weather balloon, satellite, bear walking on two legs
