Banyak prediksi relativitas umum yang berbeda dengan prediksi fisika klasik, utamanya prediksi mengenai berjalannya waktu, geometri ruang, gerak benda pada jatuh bebas, dan perambatan cahaya.
Contoh perbedaan ini meliputi dilasi waktu gravitasional, geseran merah gravitasional cahaya, dan tunda waktu gravitasional. Prediksi-prediksi relativitas umum telah dikonfirmasikan dalam semua percobaan dan pengamatan fisika.
Walaupun relativitas umum bukanlah satu-satunya teori relativistik gravitasi, ia merupakan teori paling sederhana yang konsisten dengan data-data eksperimen. Namun, masih terdapat banyak pertanyaan yang belum terjawab.
Secara mendasar, terdapat pertanyaan bagaimanakah relativitas umum ini dapat digabungkan dengan hukum-hukum fisika kuantum untuk menciptakan teori gravitasi kuantum yang lengkap dan swa-konsisten.
