    if we are seeing past from JWST then why are we people spends Billions of dollars to see life or water on other planets when it is already in the past like mars and also we can’t reach or neither if we can reach there would be extinction because we were seeing the past from JSWT not present.😂

    giving a speech at toastmasters club tomorrow and i came here looking for a speech which would help me understand how to not tense up like i naturally do during speeches. this being their most recent post showed up on top and i’m really glad because not only is this interesting, she delivers it in such a soothing tone. i aspire to be able to speak like she does!

      There are quadrillions of other potentially habitable worlds in the universe. Quadrillion is a big number. The odds are heavily in favor of it. Will we ever see it? Maybe, maybe not.

      @ We don’t know the odds for us being here. But we do know that potentially habitable worlds (and the ingredients for life) are very common, we have many in our own solar system. Forgive me for saying, but I think it is hubristic to think we are alone in the universe, and further that it’s a hubris born out of religious anthropocentrism, and simply the need to feel special. It’s the same reason we hang on to the idea that we are the only conscious animals, when that notion is obviously false.

    I am here to answer this question: no, we are not the only intelligent creatures in the whole universe. Even on Earth, some creatures exceed our imaginable intelligence by a great margin(THERE ARE CREATURES OTHER THAN HUMANS) who know more than HUMANITY has known from the beginning of time !

    Meanwhile, disclosures and hearings are happening on capital hill, ships are being reported all over the planet and hundreds of black project insiders have come out. Then there’s the majority of countries that have entirely disclosed all documents related to ufo’s/uap’s etc.

    Other intelligent beings exist but are extremely far away we cannot see, let alone make contact with them. Our existence is but a blink of an eye compared to the age of the universe. We are separated by unimaginable distances and time scales, a little daunting yet so fascinating. Possibly when one civilization is just starting out, another is on the verge of extinction.

Unboxing Apple’s New $549 AirPods Max 2 in Purple

At first glance, the AirPods Max 2 don’t seem like much of an upgrade from their predecessor. But when you factor in the improved noise canceling, sound quality, voice-calling performance and new features, they do seem to be about 20% better than the previous model. That may not seem like a huge difference, but it’s…
