I lost at level 2.

2. Samuel Okeke says:

Is there any explanation for toddlers, maybe I would understand that

3. Pastifier says:

Shouldn't it be T_m/T_s in the Teen level? Since 2L is the distance covered by the photon to measure a unit of time in the stationary clock, wouldn't T_s = 2L/c? Similarly, T_m = 2D/c. I think this also makes more sense, since as time increases for the clock in motion, it's perceived to be slower. More time = slower. I don't know though, the idea is still more or less the same, just wanted to check

4. stu Art says:

I can understand time way better than you. Its not difficult.

5. Kareem Tk says:

unfortunately, It seems surprising that the real problem of traveling back in time is not considered here

6. SRIDHARAN SRINIVASAN says:

He is nothing like sheldon

7. Ali Abbas says:

nice

8. shrinivas apte says:

The RIDICULOUS IDEA/CONCEPT Of time dialation cannot be proved because you cannot travel at or near the speed of light.

thanks but I'm not going past the kids level.😂😂😅😅
