New theory suggests time is an illusion created by quantum entanglement - Lemmy.World

I thought it was widely agreed that time was a construct?
In relativity time is a real dimension like space , but of a different type, and your speed in time depends on your speed in space and on your proximity to big masses, like planets. This kind of physics is necessary to keep the satellites synchronised otherwise their clocks go at a different speed from those on earth, so this is all very real and confirmed.
The way i understand it is that a faster or heavier object has more energy, thus bends spacetime more.

It’s far stranger than that.

The problem that shows exactly how tangled the problem is, is this: accelerating is the same as gravity.

Not “they feel the same” or “We can compare them” or " They’re similar in many ways" no, I mean literally. They are the same thing. This has been proven.

The force that is making you stick the planet is the same as being in a car and driving constantly faster and faster forever.

If this makes zero sense to you, that’s good, it means you’re human. But it also means that our vision of the universe is radically different than whatever kind of objective reality is out there, if there is one.

(What gives is time. Time is what’s changing when you move through space AND when in a gravitational field. You can also study this field for decades and barely come closer to being able to visualize it. Our brains were not meant.)

But this is consistent with what i said? Not moving and no mass = frozen in spacetime. Which is why it needed big bang as external factor to spread spacetime. Right?

Not moving and no mass = frozen in spacetime

You’re always moving at the speed of light through time. When you accelerate, you are borrowing from your speed through time and converting it to speed through space. The faster you move through space, the slower you move through time. The faster you move through time, the slower you move through space.

What does it mean to move slower through time?
Time passes more slowly for you than for an outside observer, e.g., if you are moving to some place, for someone on the outside, your journey could take decades, while for yourself only minutes pass.
So moving faster at some point starts to become slower because everything around you has the benefit of having more time to move?

They’re talking about time dilation.

Objects with no mass traveling at light speed in a vacuum don’t experience time.

A photon, traveling through a vacuum for forty years, from its perspective, leaves the instant it arrives.

Likewise, if you can travel at the speed of light for forty years and came back to earth, your twin would age forty years and you wouldn’t age at all.

At a much smaller scale we have to use time dilation to keep clocks and space running at the same time as clocks on Earth. Because in geosynchronous orbit they are traveling faster than objects on the ground.
