The energy requirements are impossible. Imagine a spacecraft for interstellar space weighing 10,000 kg. By way of comparison, the Apollo Lunar Module weighed 15,103 kg.

How much energy would it take to accelerate it to 100,000 km/s, or a third of the speed of light? No matter how quickly this speed is reached, this total energy needed is:

E = ½mv²
= ½ × 10,000 kg × (100,000,000 m/s)²
= 50 exajoules (5 × 10¹⁹ J)
Or about the entire world’s consumption of energy for a month. What possible source could produce such an enormous amount of energy? How could that energy source be stored in so small a space as the Lunar Lander?

She's a reliable source (and she discussed this). You're not.

You’re going to need more crystals.

Or how about the expansion of the Universe in the first place added to the distance between galaxies? You know, billions of light years... And I thought Kamala Harris getting a law degree was not possible LOL!

Going FTL is only theoretical (right now) and it is done in massless or nearly massless objects. Anything larger than a grain of sand becomes exponentially problematic in energy terms

You should watch the video. She explains that.
