This video looks at the earliest experiments to measure the speed of light, explaining the methods, challenges, and breakthroughs that shaped our understanding of physics. Defense Department says ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might ...

Here’s what you’ll learn in this story: Time might actually have 3 dimensions. But it also means that the space would actually be one-dimensional, instead of the three dimensions we’re familiar with.

Nearly 50 participants, representing 20 civil society organisations, community-based organisations, and grassroots groups working in Adivasi areas across Andhra Pradesh, participated in a workshop ...
