California-based startup Relativity Space is one of many launch startups, but it stands out for its 3D-printing approach to manufacturing rockets while also pursuing fully reusable rockets. Relativity ...

Relativity Space Inc. co-founder Tim Ellis wanted to revolutionize the rocket industry with 3D printing. He persuaded big-name investors from BlackRock Inc. and Fidelity Investments to Mark Cuban and ...

Einstein's theory of general relativity, published in 1916, built upon his earlier work, including special relativity and the mass-energy equivalence, both published in his "Annus Mirabilis" in 1905.

A splashy California-based launch company named Relativity Space shared a photo of sleek-looking rocket hardware on its social media channels last week. The image featured an impressively large ...

When black holes collide, the impact radiates into space like the sound of a bell in the form of gravitational waves. But ...

When the theory of relativity appeared in the early 1900s, it upended centuries of science and gave physicists a new understanding of space and time. Isaac Newton saw space and time as fixed, but in ...

Engineers have found a way to shepherd microrobots with no wires, no radios, and no onboard computers. Instead, they steer them with light patterns designed using the same math physicists use to ...
