I think you’re probably misremebering what you read, so let’s first set it right.

The time always depends on the observer. If you’re going at the speed close to the speed of light (let’s say 0.99c, that is 99% of the speed of light), the time will slow down for you from the point of view of others who aren’t moving. If you go this fast, it will look like you were slowed down to the others. You yourself will feel normal and everyone else will look sped up. This effect is the larger the closer to the speed of light you go. We’ll get to the speed of light and faster in a minute.

If you went to the moon and back at 0.99c, to everyone on earth, it will look like it took you just a tiny bit less timw then it would take light, I think 2.5 seconds or so. To you, it would feel much faster, I didn’t calculate it but let’s say 0.1 second. There’s no way you would come back to distant future of Earth after a single trip to the moon.

You could come back to the distant future if you went much further. If you spent a year at 0.99c, much more time would pass on earth. If you kept looking, you would spend a year watching earth at fast forward. In the meantime, earthlings will spend many years wathing you slowed down from their point of view. For you it would feel like a year, for Earth, it would feel like many years, because the flow of time depends on your speed and there is no universal reference time.

Now let’s get to the speed of light. First of all, it is impossible for anything with mass to reach the speed of light. As you approach speed of light, the amount of energy needed to accelerate increases and you need infinite amount of energy to reach the speed of light, which you obviously can’t have. Massless particles, like photons, that is light, move at the speed of light. Hence speed of light :-) It is said that they don’t percieve time, they are sort of simultaneously everywhere along their path from their point of view. Easy to say, hard to imagine. But no dip is happening. From the point of view of someone not moving, just standing on Earth, if you are speeding up, you appear to be moving slower and slower and if you reached the speed of light, you would appear to stop moving altogether. From your point of view, you would feel normal, but Earth would be more and more sped up and then I guess you would be everywhere at once and time would stop to have a meaning? BTW, observing stuff would in fact be problematic, since you need light for that and getting light at the speed of light doesn’t quite work and there’s a bunch of interesting other complications even before that.

To get to speeds faster than speed of light is even more impossible. But there is a theoretical framework for particles faster than speed of light called tachyons. In a way, they are an opposite. They have to be faster, never can reach the speed of light and the closer to the speed of light they are (and therefore the slower they are), the more energy they need to slow down further. They are said to move backwards in time. They have not been showed to exist (once it looked like they might, but it was a technical issue with measurements). I know very little about them.

BTC? No way, that’s way too sane. It’s going to be DOGE.

It says you still need eggs. Can you replace them and make it from blood, beer, flour and blood?

Cool, so far, I only heard about “dy”

Tell me more!
