General relativity, also known as the general theory of relativity, and as Einstein's theory of gravity, is the geometric theory of gravitation published by Albert Einstein in 1915 and is the current description of gravitation in modern physics.
[3] [4] [5] It introduced concepts including 4-dimensional spacetime as a unified entity of space and time, relativity of simultaneity, kinematic and gravitational time dilation, and length contraction. In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in the ...
Venture-backed startup Relativity Space, which aims to build the world's first fleet of 3D-printed rockets, said on Tuesday it has raised $650 million from a raft of new investors including ...
Relativity Space aims to vastly simplify the incredibly complex machine that is a launch vehicle by 3D-printing it from tip to tail fins. Co-founder and CEO Tim Ellis will be joining us at TC ...
3D-printed rocket startup Relativity Space has raised a $650 million Series E, bringing its total raised to more than $1.2 billion. Relativity’s post-money valuation now stands at $4.2 billion ...
In special relativity, energy is closely connected to momentum. In special relativity, just as space and time are different aspects of a more comprehensive entity called spacetime, energy and momentum are merely different aspects of a unified, four-dimensional quantity that physicists call four-momentum. In consequence, if energy is a source of ...
The theory of relativity does not have a concept of absolute time because there is a relativity of simultaneity. An event that is simultaneous with another event in one frame of reference may be in the past or future of that event in a different frame of reference, [ 6 ] : 59 which negates absolute simultaneity.
