Physicist explains Time Dilation #astrophysics

[Tommy-Tom-Tom]

That's the best explanation of space-time I've ever heard

[bernieflanders]

Best explanation. His books are incredible. The fabric of the cosmos is just amazing with plenty of comprehensible explanations to complex subjects. Try it out

[DiegoM]

It's like a x-y diagram where x is time and y is space. When you don't move in space you only move in time so you will have a line parallel to the time axis because the value of time is constant and the value of space is zero. When you start to move in space that line start to turn towards the space axis and when you reach the speed of light, you only move in space and not in time, the line is now parallel to the space axis because your time value is zero.

That's why running makes you younger 😂

This makes so much sense, but it still melts my brain 🤯

[sagarxedits]

That explains time stops at speed of light

[WebbCrypto]

If you were hypothetically moving at the speed of light, according to the theory of relativity, time as experienced by you would appear to stand still. This concept is known as time dilation.

To clarify, from the perspective of an observer moving at a slower speed relative to you, time would appear to pass slower for you as you approach the speed of light. As you approach the speed of light, the time experienced by an observer on Earth would appear to be passing faster relative to you. However, it's important to note that from your subjective experience, time would still appear to be moving at its normal pace.

It is also worth mentioning that it is impossible for objects with mass to reach or exceed the speed of light, according to our current understanding of physics. This is because as an object with mass approaches the speed of light, its relativistic mass increases, requiring an infinite amount of energy to continue accelerating.

I love Brian Greene. I could listen to him all day long 🤓💙

[vunnnamvarshini]

The most important principle for time travel to the future

[deadplex]

Bro so basically we have a finite amount of motion to use at any given point hence when we max out our speed time don’t exist and when we don’t move at all, time goes fastest

We're also sat on a rock hurtling through space.

[sachmuch]

At last i am able to grab this concept....thanks you....great regards for such a great again.

[KynaruHelio]

It all depends on your perspective we're constantly moving through space at incredible speeds

[maf]

I have so much questions like aren't we already moving faster than the speed of light with the expansion of the universe. And i was told if u were to move at the speed of light in a Rocket u would experience much less time passing by (it goes slower) but we already move at the speed of light. So where is the difference between moving with the milkyway or with a rocket and would time go much faster if the universe stopped expanding

[waynefisher]

Time only helps our days/months/years. Or to calculate, when you think about it. Only we know time

[SurinderKumar-osil]

Sir. Time
Motion of time mean in sphariclly in circullaly
Other in straight it may vary

[merovingian]

What happens if we were in a spacecraft outside the galaxy not exposed to effects planets, stars, or black holes? In a spacecraft sitting in the space time fabric.

[chasharris]

I have't thought about it like that before.

[jellyfrancis]

That's an evidence of 2nd law of thermodynamics and there's connection between entropy and time ❤
